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,

((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 */
