Sql server cpu utilisation

Sql server cpu utilisation

 Days ago I wanted to know which query is taking lots of time and cpu utilisation for execution.
and I came to one blog from where I copied below query. It tells details of all query. You need to fire it on your SQL server to know more.

SELECT
    substring(text,qs.statement_start_offset/2
        ,(CASE   
            WHEN qs.statement_end_offset = -1 THEN len(convert(nvarchar(max), text)) * 2
            ELSE qs.statement_end_offset
        END - qs.statement_start_offset)/2)
    ,qs.plan_generation_num as recompiles
    ,qs.execution_count as execution_count
    ,qs.total_elapsed_time - qs.total_worker_time as total_wait_time
    ,qs.total_worker_time as cpu_time
    ,qs.total_logical_reads as reads
    ,qs.total_logical_writes as writes
FROM sys.dm_exec_query_stats qs
    CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) st
    LEFT JOIN sys.dm_exec_requests r
        ON qs.sql_handle = r.sql_handle
ORDER BY 3 DESC
