SQL Optimizer for SAP ASE 3.8 - Release Notes

SQL Optimizer Window

The SQL Optimizer window allows you to enter a SQL statement for optimization. The optimization process analyzes the original SQL statement entered in the SQL Editor pane and uses the built-in Feedback-Searching engine to reproduce a list of new, semantically equivalent SQL statements.

The SQL Optimizer supports only a single SELECT, SELECT INTO, DELETE, UPDATE, or INSERT SQL statement. To optimize SQL within Transact SQL, use the SQL Scanner module to identify potential problematic SQL statements within the Transact SQL code. Then optimize each SQL statement in the SQL Optimizer module.

The SQL Editor pane of the SQL Optimizer window is where you input your original SQL statement so that you can optimize it.

SQL Text

The top left pane is used to enter and display SQL statements. The SQL Editor tab allows you to enter the SQL statement you want to optimize. When a SQL statement is copied to this pane from other modules, the optimization process automatically begins.

After optimization, multiply tabs are added to display the optimized SQL statements.

SQL Information

The top right pane [SQL Information] displays SQL information according to the button you select from the button bar at the top of this pane. These buttons include: query plan, abstract plan, and Information (SQL classification and warning messages), All Records, and First Record. The SQL Information Pane provides detailed information about the SQL statement.

Run Time Information

The Run Time information displays in three tabs in the bottom pane.
