Control a query productivity
You can view a query productivity on the query plan. It allows you to view the sequence of actions performed by the database server in the process of the query execution, and the amount of system resources used for the query execution.
If necessary, you can specify that the Plan tab appears automatically upon query execution in SQL Editor: select the Show actual execution plan on query execution option available within the Tools | SQL Editor section of the Environment Options dialog.
