What do you need to start working with MySQL
Manager
EMS MySQL Manager is developed for working with the MySQL Server, so first of all you must
have a possibility to connect to some local or remote MySQL Server to work with MySQL
Manager. Besides you need your computer to meet the minimal system requirements. Pentium 166
and 32 MB RAM recommended.
What is MySQL?
MySQL is the world's most popular Open Source Database, designed for speed, power and
precision in mission critical, heavy load use. The MySQL database server embodies an ingenious
software architecture that maximizes speed and customizability. Extensive reuse of pieces of code
within the software and an ambition to produce minimalistic but functionally rich features has
resulted in a database management system unmatched in speed, compactness, stability and ease of
deployment. The unique separation of the core server from the table handler makes it possible to
run MySQL under strict transaction control or with ultra fast transactionless disk access, whichever
is most appropriate for the situation.
Today MySQL is the most popular open source database server in the world with more than 2
million installations powering websites, datawarehouses, business applications, logging systems
and more. Customers such as Yahoo! Finance, MP3.com, Motorola, NASA, Silicon Graphics, and
Texas Instruments use the MySQL server in mission-critical applications.
You can download MySQL Server from http://www.mysql.com/downloads/index.html (download
is free).

CHAPTER 2
DATABASE MANAGEMENT
Creating Database
If you have no database on local or
remote server, you can create a new
database right from the MySQL
Manager. To do this click button
Create Database on the control
panel or choose the menu item
Database | Create Database.
The first step of the Create
Database Wizard is General
Options.
Set the name of the new database,
and then set the following database
properties:
?? Host - the server, where your
database will be situated (default
localhost means that the server
is situated on your machine);
?? Port the TCP/IP port for
connecting to the server;
?? Login the name, by which you
are registered on server;
?? Password - your password for
connecting to the server.
The Register After Creating option
indicates, that the Register Database
Dialog for the new database will
15
appear right after creating the database (you need to register the database to start working with it in
MySQL Manager). If you want to register your database later, uncheck this option.
When you are done, click Next to continue.
On the last step of the wizard you can view the result SQL statement for creating the database. You
cant edit it. To finish the wizard and start creating the database, click Create.
Registering Database
To make the database you created or an already existing database available for working in MySQL
Manager, you should register it. If you created this database in MySQL Manager, and Register
after creating was checked, then the Register Database Dialog is displayed automatically,
otherwise you should click button Register Database on the control panel or choose the menu
item Database | Register Database.
This is the General tab of the Register Database window.
On the Connection Info panel the database
server connection parameters are set: host, port,
user name and password. These parameters
should correspond to those set on creating the
database.
Select the database name from the Database
Name drop-down list of all the databases
available on the server and set the database alias
in the Database Alias edit field (choose any
alias that suits you; the default alias is
<database_name> on <host>). Set the
character set to use in the data grids in the
Database Font Charset edit field. If you choose
NONE (default), then the default Windows
charset will be used.
The following options are also available:
?? Login Prompt Before Connection - if this option is checked, MySQL Manager will ask you to
enter your login and password on each connection to the database.
?? Quote Identifiers - if this option is checked, all the identifiers will be quoted by the back quote
symbol ('`'). To make SQL scripts, obtained with the Extract Metadata Wizard, compatible
with elder versions of MySQL, uncheck this option. Note that this option will work only with
those servers that support quoting names.
?? Use SSL protocol - check this option to use the encrypted protocol when connecting to the
database server. Your version of MySQL Server must support SSL protocols for you could use
this option.
?? Use compression protocol - check this option to use the compressed data protocol when
connecting to the database server.
16
On the Directories tab you can set the default directories for extracting database metadata,
exporting data from the table or query result, and importing Excel, DBF or text files to the table.
On the Logs tab you can enable logging changes in the database
metadata (Enable log of metadata changes option) and enable logging
queries executed in the SQL Editor or Visual Query Builder. After
checking these options you should set filenames for storing this
information in the Metadata log file and the SQL Editor log file edit
fields.
Click button Test Connect to check the connection with the database
server. Button Copy Alias from allows you to copy the registration
parameters from one of the already registered databases and apply them
to the current database.
When you are done, click Register. If everything was correct, your
database will be registered, and its icon and alias will appear in the DB
Explorer window, on the Databases tab.
To unregister database, click button Unregister Database on the control panel or choose the
menu item Database | Unregister Database.
17
Connecting to the Database
To start working with the registered database, you should
connect to it. Just double-click the database alias in the DB
Explorer or click button Connect to Database on the
control panel to start connecting.
If connection is successful, the database alias changes its
appearance, and the Tables and UDFs branches become
available. These branches contain lists of database tables
and UDFs. After connecting to the database you can create
new objects or edit the existing through the popup menu of
DB Explorer.
To disconnect from the database, click button Disconnect
from Database on the control panel.
Register Host Wizard
If you need to register several
databases on one server, you can
register all them at once, not
registering them one by one. To do
that you should use the Register
Host Wizard. This wizard allows
you to register packs of databases
on one server.
To activate the wizard, click button
Register Host on the toolbar or
choose the menu item
Database | Register Host.
On the first step the wizard - Connection Info - you should set the server connection properties,
which are common for all the databases you register:
?? Host - server, where your databases are situated;
?? Port TCP/IP port for connecting to the server;
?? Login name, by which you are registered on server;
?? Password - your password for connecting to the server.
On the Databases step select the databases to register from those available on the server by
moving them from the Available Databases list to the Selected Databases.
18
To move all the databases from one list to another use buttons >>, <<; to move the selected
databases, use buttons >, < or drag the databases; to move one database, just double-click it.
The last step of the wizard is Registration Options. Select databases in the list and set the
following registration options for each of them. These properties are the same as in the Register
Database Dialog (see above).
Click Register when you are done to register all the databases on the host.
To unregister host, click button Unregister Host on the control panel or choose the menu item

21
CHAPTER 3
DATABASE OBJECTS :
TABLES AND UDFS
Creating Table
To create a table, select the Tables branch in the database
tree on the Databases tab of the DB Explorer, right-click and
choose item New object from the popup menu.
On the first step of the Create Table Dialog you should set
various table parameters.
Set the table name in the Table edit field. Choose the table type using the Table Type Preference
switch and the Table Type drop-down list. The following table types are available:
Non-transaction-safe types
?? MyISAM - the new binary portable table handler
that is replacing ISAM;
?? ISAM - the original table handler;
?? HEAP - the data for this table is only stored in
memory;
?? MRG_MyISAM - a collection of MyISAM tables
used as one table.
Transaction-safe types
?? Berkeley_db - transaction-safe tables with page
locking;
?? InnoDB - transaction-safe tables with row locking;
?? GEMINI - table type, developed by NuSphere Company. It is not supported in the last versions
of MySQL.
Select the row format in the Row Format edit field: default, fixed, dynamic, or compressed.
22
Set the following table options:
?? Check Sum (MyISAM only) - check this option if you want MySQL Manager to maintain a
checksum for all rows (makes table a little slower to update but makes it easier to find the
corrupted tables);
?? Delay Key Write (MyISAM only) - check this option to delay key table updates until the table
is closed;
?? Pack Keys (MyISAM, ISAM only) - set this to 1 if you want to have a smaller index. This
usually makes updates slower and reads faster;
?? Min. Rows - minimum number of rows you plan to store in the table;
?? Max. Rows - max number of rows you plan to store in the table;
?? Temporary check this option to create a temporary table.
A temporary table will automatically be deleted if a connection dies and the name is per connection.
This means that two different connections can both use the same temporary table name without
conflicting with each other or with an existing table of the same name. (The existing table is hidden
until the temporary table is deleted).
Use Union Tables when you want to use a collection of
identical tables as one. This only works with
MRG_MyISAM tables. Click the button next to the Union
Tables edit field. In the Union Tables List window you
can add a new table from the current database to the Union
Tables list by selecting it from the Union Table dropdown
list and clicking 'Add'. You can edit the list by
removing the tables ('Remove' button), replacing them with
the new ones ('Replace' button), and changing their order
('Up' and 'Down' buttons).
On the second step of the dialog you should set the
properties of the first table field. Set the field name in
the Column edit field, and select the data type for the
field from the Type drop-down list. For some of the
types size and precision can also be set. Check Not
null to forbid an empty field value. Set the following
field properties, if necessary:
?? Unsigned
check this
option to
give the
UNSIGNED attribute to the field;
?? Zerofill - check this option to give the ZEROFILL
attribute to the field;
?? Binary - check this option to give the BINARY attribute
to the field;
?? Unique - check this option to include the field to the
unique key (index);
?? Autoincrement - check this option to give the AUTO_INCREMENT attribute to the field;
?? Primary Key - check this option to include the field to the primary key.
In the Default Value edit field you can set the default field value.
23
If you have chosen the SET field type (see above), you can create a list of possible field values,
using the Values edit field. Click the button next to the edit field to activate the Values List
window. Enter the value in the Value edit field and click Add to add new value to the set. You
can edit the Values list by removing the values ('Remove' button), replacing them with the new
ones ('Replace' button), and changing their order ('Up' and 'Down' buttons).
Click OK when you are done to create the new table with the parameters you set.
The created table will be opened in the Table Editor, where you can create and edit table fields and
indices, manage table data, and so on (see below).
The table will also become available in the database tree of
the DB Explorer.
Any time you want to edit the table, you can open it in the
Table Editor by right-clicking the table alias in the database
tree of DB Explorer and choosing item Edit table
<table_name> in the popup menu. Using this popup menu you can also rename or drop the table.
Table Editor
Table Editor is a
powerful tool,
allowing you to
create, edit and drop
table fields and
indices, manage
table data and set
other table
properties. From the
Table Editor you
can activate various
MySQL Manager
tools for working
with the database table: Grant Manager, Print Metadata Dialog, BLOB Viewer/Editor and more.
In the left part of the window there is a tree of tables
subobjects: fields and indices. It allows you to access the
required object quickly. Using the Databases dropdown
button on the editor toolbar you can switch between
the active databases. The drop-down list of all the
database tables on the toolbar allows you to change the
edited database.
To manage the table fields use the Fields tab of the
Table Editor.
This tab displays all the table fields and their basic
properties (type, size, precision, etc.). To create a new
24
field right-click and choose item New Field or Insert Field (this item inserts new field after the
selected field).
To edit the field, double-click the field in the list, or select the field and choose item Edit Field
<Field_Name> in the popup menu.
To drop the selected field, choose item Drop Field <Field_Name> in the popup menu.
To create a new field with the same properties as the
selected field has, choose item Duplicate. You will be
asked for a new field name, and the field will be created.
To change the field order, choose item Reorder Fields
and set the new field order in the dialog window. Item
Copy List of Field Names to Clipboard allows you to
copy all the table field names to Windows Clipboard.
The properties of the field are set and edited in the Field
Editor. The edit fields of the editor correspond to the
edit fields of the Create Table Dialog, Step 2 (see
above). The only difference is that you can choose the
insert mode (insert the field last, first or after the field,
specified as Insert After).
When you are done, click OK to create a new field for the table or to change its properties.
The Indices tab of the Table Editor works in the same
way as the Fields one. To create a new index for the
table, open this tab, right-click in the main area and
choose item New Index from the popup menu. The
Index Editor will appear. Set the index name in the
Index Name edit field and select the fields for the index
by moving the fields from the Available Fields list to
the Included Fields. To move the fields use buttons
between the lists, drag the selected fields, or double-click
one of the fields. Choose the index order (Ascending or
Not ordered), set other index properties and click OK.
Foreign
keys tab are
available for InnoDB tables only and are supported
since MySQL version 3.23.44 (3.23.50 or higher
recommended). To view or change table type, use the
Table Properties dialog. To add the foreign key to table,
open Foreign key tab, right-click and select Add
Foreign Key item from the popup menu. This opens
the Foreign Key Editor dialog, where you can select
fields for the key.
The Foreign Key Editor allows you to select fields for
the foreign key, when you add a foreign key to the
InnoDB table.
Select fields to include into the key by moving them
25
from the Available Fields list box to the Selected Fields.
Select a table to link with the fields selected above from the Foreign Table Name drop-down list.
Select foreign fields to link with the fields selected above by moving them from the Available
Fields list box to the Selected Fields.
Note that all fields included into the foreign key must be unique, i.e. included into the primary keys
first. If there are several fields included into the primary key, the field must be the first one in the
list.
The On Delete Rule drop-down list allows you to define an action for deleting one of the fields.
The following values are available:
?? CASCADE - deletes the corresponding foreign key;
?? SET NULL - sets all the columns of the corresponding foreign key to NULL.
The On Update Rule drop-down list allows you to define action for updating one of the fields. The
following values are available:
?? NO ACTION - does not change the foreign key; may cause the primary key update to fail
due to referential integrity checks.
?? RESTRICT - produces an error indicating that the update would create a foreign key
constraint violation.
?? CASCADE - updates the corresponding foreign key to the new value of the primary key.
?? SET NULL - sets all the columns of the corresponding foreign key to NULL.
Currently you can't edit or drop foreign keys. This isn't the limitation of MySQL Manager, but the
limitation of InnoDB foreign keys.
The Description tab displays a simple edit area, where you can set optional text, describing the
current table.
The DDL tab displays the SQL text for creating the current table with all the parameters you set:
fields, keys, table type, etc. This text can't be edited, but it can be copied to the clipboard.
The control panel of the Table Editor provides the following functions:
Databases - use this drop-down menu to switch between the databases. If you switch to the
database, which is not currently active, youll be offered to connect to it. After you switch to the
new database, the first table of this database becomes active in the Table Editor. To switch
between the tables, use the drop-down list of the current database tables in the middle of the panel.
Grants On Table - use this button to activate the Grant Manager for the current table, where
you can set the access grants for the table.
Save Description - this button saves the table description, set on the Description tab.
Help on SQL - this button runs the MySQL Reference Help file mysql.chm, which is included
into the MySQL Manager installation package.
Print Table Metadata - this button allows you to print the table metadata: fields, indices,
description and DDL. The dialog window that appears after clicking this button also allows you to
preview the report before printing or design it, using the FastReport report designer.
26
Default Size - this button brings the window to its default size (restricted by the main window
and the DB Explorer).
Table Properties - this button allows you to edit the table properties, set on its creation: table
type, attributes, etc.
Commit Transaction / Rollback Transaction - use these buttons to commit or rollback the
current transaction.
Table Data Management
Table data are managed on the Data tab of the Table Editor. Data can be displayed in three
modes:
?? Grid View - view data as a
grid. The columns
correspond to the fields,
rows - to the records. To
navigate through the table
data use navigation buttons
at the top of the area. Button
+ inserts a record at a current
position, button ? deletes the
record. To edit the record,
click it in the grid and enter
the new value. To confirm
the changes you made, click
button ??, to cancel them
click ??. Clicking the field title allows you to switch the mode of sorting records by this field
(ascending or descending). You can multi-select the fields by click the row captions with the
buttons Shift or Ctrl down. It allows you to delete several records at once.
?? Form View - view data as a form. On the form a current record is displayed: field name and its
value. This view mode also has a control panel, which allows you to switch the records. If these
data are available for editing, you can do it on this form. Each field has a Null switch, which
allows you to clear the field value quickly; near each number field a calculator button is placed
(calculator field automatically fills the current field); near each date field calendar button is
placed (date, selected in the calendar, automatically fills the current field); near each BLOB
field the button for calling the BLOB Editor (see below) is placed.
?? Print Data - data are displayed in the way they will be printed, in WYSIWYG mode. You can
change the view scope, save a report to file and set page parameters.
To switch these modes use buttons at the bottom of the main area.
Button Export Data on the toolbar allows you to export table data to file (14 formats are
supported: MS Excel, HTML, TXT, DBF, RTF and more). Button Export Data as INSERT
Statements allows you to export data to the SQL script as SQL statement INSERT.
27
Using button Import Data
you can import data from MS
Excel, MS Access, DBF, TXT or
CSV file. Load Data reads
rows to the table from the text file.
If there are BLOB fields in the
table, you can edit them, using
the BLOB Viewer/Editor. The
editor is called by clicking button
BLOB Editor on the control
panel.
The window of the editor is divided into two areas: object tree area and data view/edit area. In the
object tree you can view the current database and the database table, edited field belongs to, and in
the data area you can view BLOB data in different formats by choosing the proper tab
(Hexadecimal, Text, Rich Text, Image and HTML).
Data, performed as Image or HTML are not available for editing. Image tab supports the following
image formats: bitmaps, WMF, icons, JPEG and GIF.
The toolbars of the editor allows you to load and save files (buttons Load from File and Save to
File ), navigate through records (the navigation panel is the same as on the Data tab of the
Table Editor) and provide various tools for editing text.
When you are done editing BLOB, just confirm the changes you made and close the editor.
BLOB Viewer/Editor is available only in the Professional Edition of MySQL Manager.
UDF Editor
The UDF Editor allows you to declare new UDFs and
to edit the existing declarations. To declare new UDF,
right-click on the UDFs branch in the database tree of
the DB Explorer and choose item New Object in the
popup menu. To edit the existing UDF, right-click the
UDF alias in the database tree of the DB Explorer and
choose item Edit UDF <UDF_name> in the popup
menu.
Set the name of the new UDF in the Name edit field.
Select the type of the returned value (STRING, REAL or INTEGER) from the Returns drop-down
list. Set the filename, identifying the library that contains the UDF in the Library Name edit field.
Note that in the current MySQL Server version UDF libraries are supported only by UNIX systems.
Check Aggregate to make the UDF aggregate. Aggregate functions work exactly like the native
MySQL GROUP functions like SUM or COUNT ().
28
On the DDL tab you can view the SQL
text for creating the UDF with the
properties you set. This text cant be
edited, but can be copied to the clipboard.
When you are done, click button
Compile on the toolbar to compile the
UDF.
To call the MySQL Reference, click button Help on SQL on the toolbar.
Button Default Size brings the window to the default size (restricted by the main window and
the DB Explorer).
The drop-down list of the current database UDFs on the toolbar allows you to switch the edited
UDF.

CHAPTER 4
DATA MANIPULATION
Export Data Dialog
You can export data from table or query result to
any of 14 available formats (MS Excel, MS
Access, MS Word, RTF, HTML, PDF, TXT and
more). Export Data Dialog is a very powerful
tool, allowing you to export data easily and
quickly, and set various export options. It is based
on EMS QuickExport Component Suite (check
http://www.ems-hitech.com/quickexport/ for
details).
To call the Export Data Dialog, select the table in
the DB Explorer, right-click and choose item
Export Data from the Data Manipulation
submenu or open the Data (Results) tab of the
Table Editor (SQL Editor or Query Builder),
click button Export Data on the toolbar or right-click and choose item Export Data.
On the Export Type tab choose the file type to
export data to and set the filename in the
Destination file edit field (use button to
browse for files). Check Open file after export to
open the result file in the appropriate program
right after export.
If you dont want all the fields to be exported,
select the fields to export on the Fields tab. Note,
that if your table contains BLOB fields, they will
be not exported default.
To choose the fields for export, move them from
30
the Available Fields list to the Included Fields one. To move the field from one list to another
double-click it or select it (use Ctrl or Shift to select multiple fields) and click button > or <. To
move all the fields click button >> or <<.
On the Formats tab you can change the formats
of the exported fields, if necessary. You can also
define your own formats for numeric and
Date/Time fields, using the User tab. These
fields (if there are any in your table) are available
in the list. Choose the format of the field from the
drop-down list of the Formats column and edit it
if necessary. You can see the example of the result
value if the Sample column.
The default column captions in the result table
correspond to the field names of the source table,
but you can edit these captions on the Captions
tab of the dialog, if necessary. This tab is
unavailable for DBF export type.
The last tab of the dialog contains specific options for the selected export type. The following
options are available:
HTML Options
Preview. This tab allows you to define the colors
of various elements of the result HTML document,
such as: default font color, header font color, table
font color, background colors and link colors. To
change the color of some element, just click this
element and set the color you need. You can also
use various HTML templates to make the result
document look in the way you need. Select a
template from the Template drop-down list or
click Load template to browse for templates. If
you have changed some HTML elements
manually and you like the result, you can save it
as a template for future using by clicking Save as
template button.
?? Basic. This tab allows you to define the title of the result document and set the mode of the CSS
(Cascade Style Sheets) using. The default CSS using is internal, but you can set to external and
define your own CSS file in the CSS file name edit field.
?? Advanced. On the Body options panel you can set the default font name of the result document
and set the document background. In the Advanced attributes edit field you can define any
attribute values for the HTML tag <BODY>.
?? The Table options panel allows you to define such attributed as Cell padding,
Cell Spacing and Border. In the Advanced attributes edit field you can define
any attribute values for the HTML tag <TABLE>.
?? The Multi-file export panel allows you to export your data not to a single
HTML document, but to a number of documents. Check option Use multi-file
export to enable this mode and define the maximum number of records in each
result file in the appropriate edit field.
31
Excel Options
The Data Format tab allows you to define a
specific format for each data column, header,
footer, column captions and aggregate functions.
Select the field from the Fields list or select an
element of the result Excel sheet (captions, footer,
etc.) from the Options list and set its font, borders
and fill. All the changes you make are displayed in
the sample cell. For data columns you can also
define aggregate functions ('Aggregate' tab): AVG
(average value), MAX (maximum value), SUM
(sum of the values), and MIN (minimum value).
The aggregate function is added to the cell under
the column. Click 'Reset item' to reset all format
setting for the current item, click 'Reset all' to reset format settings for all items.
You can also define repeating styles for data columns or rows on the Styles tab. Click button to
add a style and set its format. After you define all the styles, set the strip style to 'Col' or 'Row' (on
this depends if these styles will be applied to columns or rows). To delete a style, use button . To
load and save styles use buttons and .
The Advanced tab allows you to define headers and footers of the result document pages (the
default page footer is page number) and the sheet title.
Access Options
This tab allows you to set the MS Access export
options. There you can set the Table Name in
appropriate field, and check the Create table if it
does not exist in database option to enable
creating new table, if it does not exists.
RTF Options
This tab is available only if the chosen export type
is MS Word or RTF. It allows you to define
properties of the default document font and row
header font.
PDF Options
This tab allows you to select the document font in
the list at the left (Header Font, Caption Font, Data Font, Footer Font) and set its properties at the
right - font name, encoding, size and color. The Sample box shows how the selected element will
look like in the result PDF document.
Set options for displaying the table in the result PDF document in the Grid Options.
XML Options
This tab allows you to set the encoding of the result XML document and define if the result
document will be standalone by checking/unchecking the 'Standalone' option.
When you are done click Start Export to start export. If Open file after export was checked, the
result file will be opened in the appropriate program.
Export Data Dialog is available only in the Professional Edition of MySQL Manager.
32
Export Data as INSERT Dialog
You can export data from table or query result as SQL statement INSERT to the SQL script. After
that youll be able to execute this script and load all the exported data to another table. This can be
useful for data transfer, e.g. from one database to another.
To call the Export Data as INSERT Dialog, select
the table in the DB Explorer, right-click and choose
item Export Data as INSERT from the Data
Manipulation submenu or open the Data (Results)
tab of the Table Editor (SQL Editor or Query
Builder), click button Export Data as INSERT
Statements on the toolbar or right-click and
choose item Export As INSERT.
First of all you should set the filename for the result
script in the File Name edit field (use button to
browse for files). The default file name corresponds
to the source table name and has the extension 'sql'.
The field Table Name contains the name of the
table to use in the result INSERT statement (e.g.
INSERT into countries). This name does not result
the source table, it changes only the result SQL statement.
The Add CREATE TABLE statement option inserts the SQL statement CREATE TABLE
<table_name> to the result script before the INSERT statement. The name of the created name is
defined in the Table Name edit field. After checking this option the Create Table tab becomes
visible and active, where you can edit the statement.
On the Fields tab the list of fields for export is set. All the table fields are included to the
Included Fields list default; if you dont want some fields to be exported, move them back to the
Available Fields list. To move the field from one list to another double-click it or select it (use
Ctrl or Shift to select multiple fields) and click button > or <. To move all the fields click button >>
or <<.
The Options tab allows you to define the following export options:
?? Replace non-print characters in strings with spaces - if this option is checked, all the nonprint
symbols will be replaced with spaces in the created file.
?? Insert 'COMMIT' after each ... records - this option allows you to define the number of
records, after exporting which the COMMIT statement will be automatically inserted to the
created file.
?? Load script into Script Editor after export - if this option is checked, the created file will be
opened in the Script Editor after export.
When you are done, click Export to start export. If Load script into Script Editor after export
was checked, the result SQL file will be opened in the SQL Script Editor.
Export Data as INSERT Dialog is available only in the Professional Edition of MySQL Manager.
33
Import Data Wizard
You can import data to the table from MS Excel, MS Access, DBF, TXT or CSV file, using the
Import Data Wizard. This wizard is a very powerful tool, allowing you to import data easily and
quickly, and set various import options. It is based on the EMS QuickImport Component Suite
(check http://www.ems-hitech.com/quickimport/ for details).
To activate the Import Data Wizard,
select the table in the DB Explorer,
right-click and choose item Import
Data from the Data Manipulation
submenu or open the Data tab of
the Table Editor, click button
Import Data on the toolbar or
right-click in the grid and choose
item Import Data in the popup
menu.
On the first step of the wizard you
should choose the file type and set
the filename of the source file (use
button to browse for files). If you
choose Import from CSV then you should also select the character, delimiting columns in the
source table. Click Next to proceed to the next step.
Step 2 allows you to set the correspondence between the source table columns and the database
table fields. It varies for each import type.
Import from Excel
Select the database table field from
the Fields drop down-list and select
the cells to import to this field in the
grid. To select column or row in the
grid, just click its caption. You can
also set this value manually in the
Cells edit field. Then select the next
field and set the cells for this field. If
the source table columns (or rows)
and the database table fields are
ordered in the same way, you can set
the correspondence automatically by
clicking button Auto fill cols (or Auto fill rows). The first table field will correspond to the first
source table column (or row); second field to the second column (row), etc. If the first rows (or
columns) of the source table contains data, not intended for import, you can skip them by setting the
appropriate value in the Skip row(s) (or Skip col(s)) edit field.
34
Import from Access
When you choose import from the
MS Access file, the Select Source
tab becomes available.
First select the data source for import
- MS Access table or SQL query. If
you choose import from a table, then
you should select a table name from
the list, if you choose to import from
a query, you should set the query
SQL text in the lower area, e.g.:
SELECT Name, Capital FROM COUNTRY WHERE CONTINENT='South America'
This text can be saved or loaded to/from SQL flea, using the Save and Load buttons at the
right respectively.
Import from DBF
First select the database field from
the Table fields list. Then select the
corresponding field in the
<table_name>.dbf list.
Click button Add to link these
fields. These fields will be added to
the list at the bottom of the window.
Repeat these operations for each
database table field. If you want to
remove the accordance you set,
select the linked fields in the bottom
list and click button Remove. If the source table fields and the database table fields are ordered in
the same way, you can set the correspondence automatically by clicking button Auto fill. First
field of the source table will correspond to the first field of the database table, second field to the
second field, etc.
Import from TXT
First select the database table field
from the 'Fields' drop-down list.
Then set two separator lines to
delimit the source table column.
Click to add a separator, double-click
to delete one. Drag separators to
change the column width. You can
also set the column starting position
and the column width manually in
the edit fields 'Pos' and 'Size'. When
you set the separators correctly,
proceed to another field and repeat
35
these operations for each database table field. If you don't want some first rows of the source table
to be imported set the number of such rows in the 'Skip ... first line(s)' edit field.
Import from CSV
If the delimiter you have defined on
the first step was found in the source
table, then you will find the table
columns already separated and
delimited. Select the database table
field from the 'Fields' drop-down list.
Then click the corresponding source
table column or set the 'Col' value
manually. Repeat these operations
for each database table field. If the
source table fields and the database
table fields are ordered in the same
way, you can set the correspondence automatically by clicking button Auto fill. First field of the
source table will correspond to the first field of the database table, second field to the second field,
etc. If you don't want some first rows of the source table to be imported set the number of such rows
in the 'Skip ... first line(s)' edit field.
When you are done, click Next to proceed to the next step.
On the step 3 of the wizard you can edit the formats of the imported fields.
On the Base Formats tab the following format options are available:
Decimal separator - set a character,
which delimits the decimal parts of
the imported numbers.
Thousand separator - set a
character, which separates the digit
groups in the imported numbers.
?? Short date format, Long date
format, Short time format,
Long time format - use these
edit fields to set the date and time
formats.
?? Left quotation - set a character
or a number of characters, which
denote quoting in the imported strings.
?? Right quotation - set a character or a number of characters, which denote unquoting in the
imported strings.
?? Quotation action - you can select 'Add' to add quotation marks to each imported string or
'Remove' to remove all the quotation marks from the imported strings. 'As is' saves the original
quotation marks.
?? Boolean true - set some variants of TRUE value representation in the imported table, e.g. 'Yes'
or '+'. Use new line for each new variant.
36
?? Boolean false - set some variants of FALSE value representation in the imported table, e.g. 'No'
or '-'. Use new line for each new variant.
On the Data Formats tab you can customize the format of each imported field in case when
additional formatting is required. Select the field in the 'Field Name' list and set its format in the
proper edit fields.
Generator
?? Value - use this edit field to set
the initial value of the
autoincrement field.
?? Step - set the step of the
autoincrement field. If it is 0 then
the value of the generator will be
ignored.
Constant
Value - use this edit field to set the
constant value of the field.
Default
?? Null - set the value, which will be understood as NULL to set the default value.
?? Default - set the default value of the NULL field.
Quotation
?? Left quotation - set a character or a number of characters, which denote quoting in the
imported string.
?? Right quotation - set a character or a number of characters, which denote unquoting in the
imported string.
?? Quotation action - you can select 'Add' to add quotation marks to the imported string, 'Remove'
to remove all the quotation marks from the imported string or 'As is' to save the original
quotation marks.
String conversion
Char case - set the case of the imported string. 'As is' saves the original string case, 'Upper' sets the
whole string to upper case, 'Lower' sets the whole string to lower case, 'UpperFirst' sets the first
letter of the string to upper case, 'UpperFirstWord' sets the first letter of each word to upper case.
Char set - set the char set of the imported string to ANSI or OEM. 'As is' saves the original string
char set.
Click 'Next' to proceed to the next step.
On the last step of the wizard the following import options are set:
?? Commit after done - check this option to commit the transaction after import is finished.
?? Commit after ... records - set a number of records, after importing which the transaction shall
be committed.
?? Import all records - check this option to import all records from the source table.
?? Import only ... first record(s) - if you don't want all the records to be imported, set a number of
records to import them from the source file. In this case only this number of records (beginning
from the first one) will be imported.
37
Note, that on each step of the wizard you can use buttons Load Template and Save Template on
the left panel, which allow you to save/restore all the import settings (file type and name, field
correspondence, format options, etc.) to/from the template file. This is very useful, if you often use
the same import configuration: you dont have to choose fields or edit field formats on each import
session you can simply load a previously saved template and skip all the unneeded steps.
When you are done, click 'Finish' to start import.
Import Data Wizard is available only in the Professional Edition of MySQL Manager.
Load Data Wizard
Load Data is a native MySQL function, which allows you to read rows from a text file to the table
at a very high speed. The Load Data Wizard guides you through the process of loading data from
file.
To call the Load Data Wizard,
select the table in the DB Explorer,
right-click and choose item Load
Data from the Data Manipulation
submenu or open the Data tab of
the Table Editor, click button Load
Data on the toolbar or right-click
and choose item Load Data.
On the first step of the wizard you
should set the name of the loaded
text file in the Filename edit field
(use button to browse for files).
Set the function attributes by
checking the following options:
?? Local - if this option is checked, the file is read from the client host. Otherwise, the file must be
located on the server.
?? Low priority - if this option is checked, loading data is delayed until no other clients are
reading from the table.
?? Concurrent - if this option is checked, other threads can retrieve data from the table while
loading data is executed.
?? Replace - if this option is checked, new rows replace existing rows that have the same unique
key value.
?? Ignore - if this option is checked, input rows that duplicate an existing row on a unique key
value are skipped. If you don't specify either option, an error occurs when a duplicate key value
is found, and the rest of the text file is ignored.
Step 2 allows you to define fields to load data to by moving them from the Available Fields list to
the Included Fields. To move the field from one list to another double-click it or select it (use Ctrl
or Shift to select multiple fields) and click button > or <. To move all the fields click button >> or
<<.
38
On the step 3 you can specify the characters, used in the data file for delimiting fields and lines.
Option 'Ignore Lines Count' allows you to specify the number of the first file lines, which will be
not loaded into the table.
When you are done, click Load to start loading. The Load Data step is automatically activated,
where you can view the operation log of the process.

CHAPTER 5
DATABASE TOOLS
SQL Editor
SQL Editor is the basic MySQL Manager tool for creating and executing database queries. It
allows you to create and edit SQL text for the query, prepare and execute queries and view the
results of execution. SQL Editor supports Quick Code and Syntax Highlight systems, which make
your work much easier.
The main area of the editor is situated on the Edit
tab. This area is provided for working with the text of
the query. For your convenience the Quick Code
system is enabled, i.e. when you type first word
symbols in the SQL text editor you are offered some
variants for the word completion in a popup list

Visual Query Builder
Visual Query Builder is a powerful tool, provided for visual building database queries. Using
Query Builder you can select tables and fields, join tables, set conditions for the selection and
perform many more query operations without knowledge of SQL. Visual Query Builder is based
on the EMS QueryBuilder Component (check http://www.ems-hitech.com/querybuilder/ for
details).
The main area of the Query Builder is the Builder area.
Here you can build your query by placing the database
tables on the area, selecting the required data and setting
links between objects.
To add a table to the query, choose it in the table list at the
right, then double-click it or drag it to the Builder area.
The selected table will appear on the Builder area with
the list of its fields. To include the table field to the query,
click at the left of the field name in the list or double-click
it to set the blue icon next to the field name. To include all
the fields, set a flag at the left of the table alias. To
remove the fields from the query, uncheck the fields; to
remove the table, close it by clicking the button ? next
to the table alias. To edit the table alias, double-click it.
To associate tables by two fields, just drag one field from
the table field list to another. This will set a link between
these tables by the selected fields. When you drop a field,
a line will appear between the linked fields. You can view and edit the properties of object
association. To view the properties, just aim cursor to the link line and a hint, containing the
association condition, will appear. To edit the properties, double click the line or right-click and
choose 'Properties' item from the popup menu. A dialog window will appear, where you can change
the association condition by choosing it from the list (=, >, <, >=, <=, <>). Also you can check or
uncheck 'Include all from <table_name>' option for each object, included into the association. Click
'OK' to confirm the changes you made. To drop a link between the tables, right-click on the link line
and choose 'Delete Link' item from the popup menu. To delete all the links of the table, click button
- next to the table alias. To insert a point to the link line, right-click on the line and choose 'Insert
Point' item from the popup menu. A new point will appear, using which you can move the link line.
It doesn't cause any changes in the query but
makes the diagram performing more obvious
and the visual building handler.
In the Criterions area you can set the selection
conditions. To add a condition, click button at
the left and select Add condition in the popup
menu. Edit the condition by clicking its parts and setting their values. Clicking the button at the left
of the condition string activates the popup menu, which allows you to add a new condition of the
42
same enclosure level, add a new enclosure level, delete the current condition, open or close the
condition, if it is composite. A simple condition string contains three fields: an argument, a
condition and a second argument (if required for the condition). Clicking each field allows you to
set its value. Clicking the argument field allows editing it as a text field. You can set a table name or
a definite value in this field. Right-clicking the field in the edit mode activates the popup menu,
which contains the 'Insert Field' function (also called by Shift+Enter). This function allows you to
choose a field from the list of all the table fields, available in the query. Clicking the condition field
activates the popup menu, where you choose the condition you need. The way of processing the
condition is set in the upper string of the area (All, Any, None, or Not all of the following are met).
Click the underlined word to change it.
The Selection area displays the output fields
of the query. It allows you to edit the names of
the query output fields, set their displaying
order and set the aggregate functions (SUM,
MIN, MAX, AVG, COUNT) for each field. To
remove the field from the list, right-click the
field row and choose Delete current row from
the popup menu. To change the input query field, double click it and then type the field name on the
keyboard or choose it from the drop-down list.
To change the output query field name, double click it and type the field name on the keyboard.
To set the aggregate function for the field, double click the field row in the 'Aggregate' column and
then type the function name on the keyboard or choose it from the drop-down list.
If you check option Include only unique records then the repeated records will not be included
into the query result.
In the Grouping Criterions area you can set
the conditions for grouping the query records.
They are set in the same way as the selection
conditions (see above). These conditions will
be included into the HAVING statement of the
current query.
Set the way of sorting the query records in the Sorting area. The field list at the left represents all
the output query fields; the list at the right contains fields, by which the query records will be sorted.
To move the field from one list to another, drag the selected field or use buttons Add and
Remove. To change the sorting order, select a field in the right list and move it using buttons 'Up'
and 'Down'. To change the sorting direction, select a filed in the right list and switch the direction
(Ascending, Descending) using button A..Z/'Z..A'.
When the query is ready, click button Prepare Query on the toolbar or press Ctrl+F9 to check
the query for errors. If there were any errors in building the query text, you will get the appropriate
message, describing the error. If everything is correct, you can execute the query by clicking button
Execute on the toolbar. This will display the Results area.
This area displays the result data returned by the query. They can be viewed in three modes (chosen
by clicking the according button at the bottom of the window):
?? Grid View - view data as a grid;
?? Form View - view data as a form: there is only one record displayed at the time, to view
another record use the navigation buttons.
?? Print Data - view data in WYSIWYG mode, ready for printing. The acquired query can be
saved to filed and/or printed.
43
These data cant be edited,
but can be exported
(Export Data item in the
popup menu or button
on the toolbar) or exported
as INSERT statement to the
SQL Script (Export as
Insert item in the popup
menu or button on the
toolbar).
The status bar displays the
number of records, acquired
while executing the query.
In the Edit area the query
text is automatically
generated while you build
query. You can edit this text
according to the rules of
SQL, and all the changes
will be displayed on the
other pages of the Query Builder.
To select the database for the query, click button Databases on the toolbar and select the
required database from the drop-down list of the available databases. The alias of the selected
database will be displayed in the window caption.
You can load a query from file by clicking button Load Query on the toolbar. To save the query
to file, click button Save Query .
To commit or rollback the current transaction, click button Commit Transaction or Rollback
Transaction in accordance.
To clear the current query, click button Clear Current Query on the toolbar.

CHAPTER 6
DATABASE SERVICES
Backup Tables
The Backup Tables Wizard allows
you to make a copy of all the table
files to the backup directory.
Currently MySQL supports backup
only for MyISAM tables and
transaction-safe type tables. Backup
Tables copies .frm (definition)
and .MYD (data) files. The index file
can be rebuilt from those two.
Note, that you cant backup tables on
remote server; backup only works on
local host. To backup tables from the
remote server, use Extract
Metadata, and then restore them using Script Editor.
To activate the Backup Tables Wizard use the menu item Services | Backup Tables.
Step 1 - Backup Path
Database - select the database from the drop-down list to backup its tables.
Backup Directory - set a path to the directory, where the database tables should be saved.
Step 2 - Backup Tables
Available Tables - a list of tables, available for backup. It is the list of all the tables, included into
the database you set on the 'Backup Path' step.
Selected Tables - a list of tables to backup.
53
To move the table from one list to another, double-click it or select it (use Ctrl or Shift to select
multiple tables) and click button > or <. To move all the tables click button >> or <<.
Step 3 - Run Backup
This page is activated automatically on clicking button 'Backup'. It displays the backup process
(Operation log) and its results (Results).
Restore Tables
The Restore Tables Wizard allows you to restore database tables, saved in advance with Backup
Tables.
To activate the Restore Tables
Wizard use the menu item Services |
Restore Tables.
Step 1 - Restore Path
Restore Directory - type the
directory name, where the database
tables are stored, or select it from the
drop-down list.
Registered database check this
option to restore the tables into the
database, registered in MySQL
Manager. Select the host and the database name from the proper drop-down lists.
Unregistered database check this option to restore the tables into the database, not registered in
MySQL Manager. Type the host and the database name or select them from the drop-down lists. Set
the Port (default 3306), login and password.
Step 2 - Restore Tables
Available Tables - a list of tables, available for restoring. It is the list of all the tables, stored in the
directory you set on the 'Restore Path' step.

54
Flush
Use the Services | Flush menu if you want to clear some of the internal caches MySQL uses. To
execute FLUSH, you must have the RELOAD privilege.
The following table illustrates the use of FLUSH:
HOSTS
Empties the host cache tables. You should flush the host tables if some of your
hosts change IP number or if you get the error message Host ... is blocked.
When more than max_connect_errors errors occur in a row for a given host
while connection to the MySQL server, MySQL assumes something is wrong
and blocks the host from further connection requests. Flushing the host tables
allows the host to attempt to connect again.
LOGS
Closes and reopens all log files. If you have specified the update log file or a
binary log file without an extension, the extension number of the log file will
be incremented by one relative to the previous file. If you have used an
extension in the file name, MySQL will close and reopen the update log file.
PRIVILEGES Reloads the privileges from the grant tables in the MySQL database.
TABLES Closes all open tables and force all tables in use to be closed.
TABLES WITH
READ LOCK
Closes all open tables and locks all tables for all databases with a read until
one executes UNLOCK TABLES. This is very convenient way to get backups
if you have a file system, like Veritas, that can take snapshots in time.
STATUS Resets most status variables to zero. This is something one should only use
when debugging a query.
Analyze Tables
The Analyze Tables Wizard allows
you to analyze and store the key
distribution for the table. During the
analysis the table is locked with a
read lock. Currently MySQL
supports analyzing only for
MyISAM tables and transaction-safe
type tables. MySQL uses the stored
key distribution to decide in which
order tables should be joined when
one does a join on something else
than a constant.
To activate the Analyze Tables
Wizard use the menu item Services | Analyze Tables.
55
Step 1 - Location
Host - select the host, where the database to analyze its tables is situated, from the drop-down list.

multiple tables) and click button > or <. To move all the tables click button >> or <<.
Step 3 - Analyze Tables
This page is activated automatically on clicking button 'Analyze'. It displays the analysis process
(Operation log) and its results (Results).
Check Tables
The Check Tables Wizard allows
you to check the database tables on
errors. Currently works only for

To activate the Check Tables
Wizard use the menu item Services |
Check Tables.
Step 1 - Location
Host - select the host, where the
database to check its tables is
situated, from the drop-down list.
Database - select the database from the drop-down list to check its tables.
Check Options
?? Quick - don't scan the rows to check for wrong links.
?? Fast - only check tables which haven't been closed properly.
?? Changed - only check tables which have been changed since last check or haven't been closed
properly.
?? Medium - scan rows to verify that deleted links are ok. This also calculates a key checksum for
the rows and verifies this with a calculated checksum for the keys.
?? Extended - do a full key lookup for all keys for each row. This ensures that the table is 100 %
consistent, but will take a long time!
56
Step 2 - Select Tables
Available Tables - a list of tables, available for checking. It is the list of all the tables, included into
the database you set on the 'Location' step.

?? Quick - do a repair of only the index tree.
?? Extended - create the index row by row instead of creating one index at a time with sorting.
This may be better than sorting on fixed-length keys if you have long char() keys that compress
very good.
Step 2 - Select Tables
Available Tables - a list of tables, available for repair. It is the list of all the tables, included into
the database you set on the 'Location' step.
Selected Tables - a list of tables to repair.
To move the table from one list to another, double-click it or select it (use Ctrl or Shift to select
multiple tables) and click button > or <. To move all the tables click button >> or <<.
57
Step 3 - Repair Tables
This page is activated automatically on clicking button 'Repair'. It displays the repair process
(Operation log) and its results (Results).
Optimize Tables
The Optimize Table Wizard should be used if you have deleted a large part of a table or if you
have made many changes to a table with variable-length rows (tables that have VARCHAR, BLOB,
or TEXT columns). Deleted records are maintained in a linked list and subsequent INSERT
operations reuse old record positions. You can use optimization to reclaim the unused space and to
defragment the data file.
OPTIMIZE TABLE works the
following way:
?? if the table has deleted or split
rows, repair the table;
?? if the index pages are not sorted,
sort them;
?? if the statistics are not up to date
(and the repair couldn't be done
by sorting the index), update
them.
Currently MySQL Server supports
optimizing only for MyISAM tables
and transaction-safe type tables.
To activate the Optimize Tables Wizard use the menu item Services | Optimize Tables.
Step 1 - Location
Host - select the host, where the database to optimize its tables is situated, from the drop-down list.
Database - select the database from the drop-down list to optimize its tables.
Step 2 - Select Tables
Available Tables - a list of tables, available for optimization. It is the list of all the tables, included
into the database you set on the 'Location' step.
Selected Tables - a list of tables to optimize.
To move the table from one list to another double-click it or select it (use Ctrl or Shift to select
multiple tables) and click button > or <. To move all the tables click button >> or <<.
Step 3 - Optimize Tables
This page is activated automatically on clicking button 'Optimize'. It displays the optimization
process (Operation log) and its results (Results).

Server Properties
Use Server Properties to view the properties of the selected
server. This window is activated via Services | Server Properties
menu item.
Use drop-down list on the toolbar to select the server.
On the Variables tab you can view a list of all server variables
and their values. These values cant be edited. The Process List
tab displays a list of all the processes, executed on the server, and
additional process information: ID, User, Host, etc.
Button Refresh on the toolbar or in the popup menu refreshes
these lists. In the Process List area item Kill process is also
available in the popup menu.
