SQL SERVER – Find Most Expensive Queries I am running the following script to find most expensive queries.

However I want to narrow it down to only queries ran on Saturday 18th October 2014
Is there any way to do this?

SELECT TOP 50 SUBSTRING(qt.TEXT, (qs.statement_start_offset/2)+1,
((CASE qs.statement_end_offset
WHEN -1 THEN DATALENGTH(qt.TEXT)
ELSE qs.statement_end_offset
END - qs.statement_start_offset)/2)+1),
qs.execution_count,
qs.total_logical_reads, qs.last_logical_reads,
qs.total_logical_writes, qs.last_logical_writes,
qs.total_worker_time,
qs.last_worker_time,
qs.total_elapsed_time/1000000 total_elapsed_time_in_S,
qs.last_elapsed_time/1000000 last_elapsed_time_in_S,
qs.last_execution_time,
qp.query_plan
FROM sys.dm_exec_query_stats qs
CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) qt
CROSS APPLY sys.dm_exec_query_plan(qs.plan_handle) qp
ORDER BY qs.total_logical_reads DESC -- logical reads
-- ORDER BY qs.total_logical_writes DESC -- logical writes
-- ORDER BY qs.total_worker_time DESC -- CPU time


ps I got this script from http://blog.sqlauthority.com/2010/05/14/sql-server-find-most-expensive-queries-using-dmv/

The server is SQL Express 2012
No, the DMVs track aggregates, not individual executions, so you can't pinpoint things like that.

Want to drill in, you'll need to capture queries using server-side trace*, extended events, management data warehouse or one of many 3rd party monitoring tools. The latter cost money but, IMHO, you get what you pay for. We have one I could recommend...

* Note: trace and profiler are deprecated, so it is highly recommended to use extended events going forward.
