Using the What-If Index function


Use these procedures to simulate the effects of adding, dropping, or updating statistics for an index using cloned structures by using the What-If Index function.

Save DDL for your What-If Index changes to a data set, and then import those changes on another statement to see the effects of the changes on that statement.

This section contains the following topics:
