SQL SERVER – Live Plan for Executing Query – SQL in Sixty Seconds #073

Yesterday I wrote blog post based on my latest Pluralsight course on learning SQL Server 2014. I discussed newly introduced live plans. For query before you execute it, you can see the estimated execution plan and after you executed you can see the actual execution plan – however, how to see a query plan while the query is still being executed. This is a very interesting question. In SQL Server 2014 we have now a new DMV, which tracks execution stats at each operator level while the query is still running. The DMV for the same issys.dm_exec_query_profiles.

I hope my earlier blog post clearly explained how live plan for executing query works. If not, I suggest you watch following quick video where I explain this concept in extremely simple words.

You can download the code used in this video from Simple Demo of New Cardinality Estimation Features of SQL Server 2014.
