BOOST NAV – How to show most 50 heavy queries on SQL SERVER

… very nice SQL Script to discover slow Sessions !!

SQL SCRIPT

SELECT TOP 50 SUBSTRING(qt.TEXT, (qs.statement_start_offset/2)+1,

ELSE qs.statement_end_offset

END – qs.statement_start_offset)/2)+1),

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
