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.

Compare tab

The Compare tab displays side-by-side Explain trees representing two statements that are being compared.

This tab is available in the Classic console only. In the New console, use the Compare dialog. For more information, see Comparing statements.

You can create a What-If scenario and compare it to the source statement or to another What-If scenario. For more information, see Comparing statements.


The Compare tab is available only if the tuning session contains two or more statements.

See Performance perspective for an example of the Compare tab.
