Enabling the Cost-Based Optimization

The cost-based optimization is enabled by default, but it can be disabled in the “Queries optimization” dialog of the menu “Administration > Server configuration” (see section Queries Optimization).

To enable/disable this optimization for a specific database, click Database management in the Administration menu, select the database and click Edit. Then, select Automatic cost based optimization on or off and click Ok. In this dialog, if “Automatic cost based optimization” is Default, the database has the configuration defined in the “Queries optimization” dialog.
