sys.dm_exec_query_stats

The “sys.dm_exec_query_stats” DMV is useful for analyzing performance stats of cached query plans in order to identify long running queries and/or procedures that might be missing indexes. I use the following script a lot, enjoy!

SELECT TOP 5 creation_time, last_execution_time, total_clr_time,
total_clr_time/execution_count AS [Avg CLR Time], last_clr_time,
execution_count,
SUBSTRING(st.text, (qs.statement_start_offset/2) + 1,
((CASE statement_end_offset
WHEN -1 THEN DATALENGTH(st.text)
ELSE qs.statement_end_offset END
- qs.statement_start_offset)/2) + 1) as statement_text
FROM sys.dm_exec_query_stats as qs
CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) as st
ORDER BY total_clr_time/execution_count DESC;
