Breaking Down Complex Execution Plans

Home / SQL Server 2005 / Breaking Down Complex Execution Plans

Peter Ward, the editor at SQL Server Performance, has published an article of mine on Breaking Down Complex Execution Plans. I go way beyond the blog entry below and show how the estimated costs in execution plans can mess you up, how to use the XML in execution plans to search through them for costly operations or operations that have mismatched estimated rows & actual rows and some other tips and tricks. Hopefully it’s worth a read.

OK, fine, but what do you think?
