I have a great bunch of sql server statements that run on sql server 2008 I try to inspect its execution plans. Actually it generates a great deal of execution plans. I want to show only the execution plans that have a specific operator(s). e.g I want to get the execution plans that have Table Scan operator.
Any way to do something like this?
thank you in advance.
