When you generate virtual index alternatives, SQL Optimizer retrieves virtual execution plans because the indexes are not physically created on the database. You can retrieve execution plans for index alternatives by creating temporary indexes. SQL Optimizer drops the temporary indexes once it retrieves the execution plans.
To fill a missing execution plan
Select an index alternative in the Alternatives pane. The Virtual Plan tab displays by default in the Execution Plan pane.
