If any table mentioned in the query has statistics stored in the data dictionary, Oracle will use the CBO.

Hi,

The execution plan for a query in oracle 9i shows "Optimizer= CHOOSE", how can i force the DB engine to use the COST based optimization for a query ?

Oracle version is 9.2.0.4.0

Thanks
