最常执行的存储过程？

Question

我们在应用程序中创建了许多低效的存储过程,我们总是推迟使其更有效率,直到我们遇到严重的数据库性能问题.

现在,我正在考虑通过最常执行的存储过程逐个修复它.

找出哪个存储过程执行最多的最佳方法是什么？

是否有一个脚本可以显示哪个存储过程执行最多？

Answer 1

使用:

SELECT TOP 10 
       qt.TEXT AS 'SP Name',
       SUBSTRING(qt.text, qs.statement_start_offset/2, CASE WHEN (qs.statement_end_offset = -1) THEN LEN(qt.text) ELSE (qs.statement_end_offset - qs.statement_start_offset)/2 END) AS actual_query,
       qs.execution_count AS 'Execution Count',
       qs.total_worker_time/qs.execution_count AS 'AvgWorkerTime',
       qs.total_worker_time AS 'TotalWorkerTime',
       qs.total_physical_reads AS 'PhysicalReads',
       qs.creation_time 'CreationTime',
       qs.execution_count/DATEDIFF(Second, qs.creation_time, GETDATE()) AS 'Calls/Second'
  FROM sys.dm_exec_query_stats AS qs
  CROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) AS qt
 WHERE qt.dbid = (SELECT dbid
                    FROM sys.sysdatabases
                   WHERE name = '[your database name]')
ORDER BY qs.total_physical_reads DESC
