Creating Tables
The Merge Table Options section is used to configure MERGE tables in MyISAM. To create a MERGE table, select MERGE
as your storage engine and then specify the tables you wish to MERGE in the UNION TABLES dialog.
You can also specify the action the server should take when users attempt to perform INSERT statements on the merge table. See
The MERGE Storage Engine for more information about MERGE tables. Again, this only applies to MyISAM tables. You may also
select the Merge Method by selecting from the drop down list box.
7.3.9. The Inserts Tab
Use the Inserts tab to insert records into the table. Clicking the OPEN EDITOR ... button on the lower right hand side opens the
Standard Inserts editor. Use this editor to add records to the table.
When you have finished adding records, press OK. The records you have added are displayed in the Inserts tab. Reopening the
editor displays all the records shown in the Inserts tab. To edit a record simply click on the field you wish to change and enter
the new data. To delete a record, click the button on the left beside the desired row and then press the Delete key. You can select
and delete all records by clicking in the top left hand column of the editor and then pressing the Delete key. Your changes will not
be applied until you press the OK button. To back out of an operation, press the CANCEL button.
Any records you add will be inserted when you forward engineer the database (if you choose the Generate INSERT statements
for tables option).
7.3.10. The Privileges Tab
Use the Privileges tab to assign specific roles and privileges to a table. You may also assign privileges to a role using the role
editor. For a discussion of this topic see Section 6.4.3.1, “Adding Roles”.
When this tab is first opened, all the roles that have been created are displayed in the list box on the right. Move the roles you wish
to associate with this table to the ROLES list box on the left. Do this by selecting a role and then clicking the < button. Use the Shift
key to select multiple contiguous roles and the Ctrl key to select non-contiguous roles.
To assign privileges to a role click on a role in the ROLES list box. Doing this displays all available privileges in the ASSIGNED
PRIVILEGES list box. The privileges that display are:
• ALL
• CREATE
• DROP
• GRANT OPTION
• REFERENCES
• ALTER
• DELETE
• INDEX
• INSERT
• SELECT
• UPDATE
• TRIGGER
You can choose to assign all privileges to a specific user or any other privilege listed in the preceding. Privileges irrelevant to a
specific table, the FILE privilege for example, are not shown.
If a role has already been granted privileges on a specific table, those privileges show as already checked in the ASSIGNED PRIV-
ILEGES list box.
