Leftover DTA Tables

Tidying Up Your SQL Server: Removing Leftover DTA Tables

SQL Server administrators and developers often use the Microsoft Database Tuning Advisor (DTA) to analyze and enhance database performance. While DTA is an effective tool, it tends to leave behind monitoring tables in the msdb database after its use.

Identifying and Removing Leftover DTA Tables

The Database Health Monitor tool offers a Quick Scan Report feature to help identify these leftover DTA tables. If you’re not actively using the Database Tuning Advisor, these tables can be safely removed.

To clean up these tables, follow these steps in SQL Server Management Studio (SSMS):

1. Connect to your SQL Server instance.
2. Navigate to a new query window connected to the msdb database.
3. Execute a script to drop the DTA tables, including commands to specifically target each leftover table.
