Monitor the running status of SQL statements in the database

When we are not using ADO. net for data interaction, but with some E/R database frameworks (such as nhib.pdf, LINQ to SQL, EF, etc.) for data interaction, it is often difficult to intuitively see the SQL statements executed in the database. At this time, we can only go to the database and execute some SQL statements to monitor the database operation. The following is an SQL monitoring script (applicable to SQL Server 2005)

 

Select creation_time n 'Statement compilation time'
, Last_execution_time n 'last execution time'
, Total_physical_reads n 'Total number of physical reads'
, Total_logical_reads/execution_count n 'number of logical reads per time'
, Total_logical_reads n 'Total number of logical reads'
, Total_logical_writes n' total number of logical writes'
, Execution_count n 'execution times'
, Total_worker_time/1000 n' total CPU time Ms'
, Total_elapsed_time/1000 n' total consumed time Ms'
, (Total_elapsed_time/execution_count)/1000 N 'average time Ms'
, 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) n'execution statement'
From SYS. dm_exec_query_stats as Qs
Cross apply SYS. dm_exec_ SQL _text (Qs. SQL _handle) ST
Where 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) Not like '% fetch %'
Order by total_elapsed_time/execution_count DESC
