Use this procedure to view the indexes present in the tables referenced in the active query.
Note: Captured indexes, object definitions, and statistics are not available for plans opened from DBQL.
Load an execution plan before viewing the indexes. For more information, see “Loading and Viewing an Execution Plan” on page 145.
1 From the menu bar, choose View > Current vs. Captured > Indexes or from the toolbar, click .
The main window is transformed. The left pane displays a hierarchical tree of the objects referenced in the query.

2 Highlight the index in the database list located in the left pane.
The indexes that existed at the time the execution plan was captured are listed in the right pane under Captured time Indexes. If the table still exists and the indexes were changed, the indexes are listed in the right pane under Current Indexes.
Note: The number of captured‑time and current indexes is listed in the upper right corner and might be helpful for comparison.
3 From the Index Type list, select the type of indexes to view.
By default, All Indexes is selected.
