Visual Query Builder
Visual Query Builder is implemented in SQL Query for InterBase/Firebird for building queries visually. The tool allows you to create and edit queries without deep knowledge of SQL. You can also prepare and execute queries, and view the results of their execution.
To open Visual Query Builder, select the Query | New Query main menu item, or use the New Query button on the main toolbar (you can also use the Ctrl+N shortcut for the same purpose), and proceed to the Builder tab of the editor window.
