Leave Collaboration
Are you sure you want to leave the realtime collaboration and continue editing alone? The changes you save while editing alone will lead to merge conflicts with the changes auto-saved by the realtime editing session.
Information
Space announcement This space provides the same content as before, but the organization of the home page has changed. The content is now organized based on logical branches instead of legacy book titles. We hope that the new structure will help you quickly find the content that you need.
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.
The procedures in this task use examples that illustrate the cumulative nature of the What-If Index process. In actual practice, after you create cloned objects on the Explain results you can perform What-If Index procedures in any order.
