Figure 5: Example SQL Script To Report On SQL Area Usage By User

Example output from the script in Figure 5 is shown in Figure 6. In the example report no one user is really hogging the SQL area. If you have a particular user that is hogging SQL areas, the script in Figure 6 will show you what SQL areas they have and what is in them. This report on the actual SQL area contents can then be used to help teach the user how to better construct reusable SQL statements.
