While it's easy to use the SQL job to perform a backup of SQL scripts, but at least it's time to write the backup script, some people feel uncomfortable, is there a simpler, more lazy way to impleme

I have been looking for some authoritative references on SQL statement performance debugging, but I may not be able to do a good job of debugging. I believe that the experience gained in practice is the most precious, and book knowledge is just a guide. This article comes from "inside Microsoft SQL Server 2008", although experienced experts make bricks. This section describes some performance analysis tools that focus on execution plans.
