SQL Server execution-plans-3 book cover

Free eBook: SQL Server Execution Plans, Third Edition

If a query is performing poorly, and you can't understand why, then that query's execution plan will tell you not only what data set is coming back, but also what SQL Server did, and in what order, to get that data.

These details will often highlight the likely source of any problem.
