Показать описание

Finding expensive queries can be challenging on SQL Server, this tutorial will help you in finding expensive queries on production. Using below DMVs
SYS.DM_EXEC_QUERY_STATS
SYS.DM_EXEC_SQL_TEXT
SYS.DM_EXEC_CACHED_PLANS
SYS.DM_EXEC_TEXT_QUERY_PLAN

First is using average logical reads, execution count and total worker time. But still people can use other combinations as well.
I have also explained how missing index can also help in finding and fixing expensive queries.
