Visual Database Tools
Verifying a Query
To avoid problems, you can check the query you have built to ensure its syntax is correct. This option is especially useful when you enter statements in the SQL pane.
Note A statement can be valid, and therefore be verified successfully, even if it cannot be represented in the Diagram and Grid panes.
Note SQL Verification can detect some, but not all SQL errors. If a query contains an error not detected during SQL verification, the database will detect the error when you run the query.
To verify an SQL statement
Right-click in the SQL pane, and select 
Verify SQL Syntax from the shortcut menu.
