1.可以通过下面的语句，得到按照执行时间排序的前10 的存储过程的执行信息：

SELECT TOP 10 a.object_id, a.database_id, OBJECT_NAME(object_id, database_id) ‘proc name‘,a.cached_time, a.last_execution_time, a.total_elapsed_time, a.total_elapsed_time/a.execution_count AS [avg_elapsed_time],a.execution_count,a.total_physical_reads/a.execution_count avg_physical_reads,a.total_logical_writes,a.total_logical_writes/ a.execution_count  avg_logical_reads,a.last_elapsed_time,a.total_elapsed_time / a.execution_count   avg_elapsed_time,b.text,c.query_planFROM sys.dm_exec_procedure_stats AS aCROSS APPLY sys.dm_exec_sql_text(a.sql_handle)  bCROSS APPLY sys.dm_exec_query_plan(a.plan_handle) cORDER BY [total_worker_time] DESC;GO

 

2.消耗前10sql语句

SELECT creation_time  N‘语句编译时间‘        ,last_execution_time  N‘上次执行时间‘        ,total_physical_reads N‘物理读取总次数‘        ,total_logical_reads/execution_count N‘每次逻辑读次数‘        ,total_logical_reads  N‘逻辑读取总次数‘        ,total_logical_writes N‘逻辑写入总次数‘        ,execution_count  N‘执行次数‘        ,total_worker_time/1000 N‘所用的CPU总时间ms‘        ,total_elapsed_time/1000  N‘总花费时间ms‘        ,(total_elapsed_time / execution_count)/1000  N‘平均时间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‘执行语句‘FROM sys.dm_exec_query_stats AS qsCROSS APPLY sys.dm_exec_sql_text(qs.sql_handle) stwhere 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;

 3.前50存储过程语句：

create view procname_view asSELECT TOP 50 a.database_id 数据库 , OBJECT_NAME(object_id, database_id) 存储过程, a.total_elapsed_time/a.execution_count AS [平均时间],a.execution_count 执行次数,a.total_physical_reads/a.execution_count ‘平均物理读写时间‘,a.total_logical_writes/ a.execution_count ‘平均逻辑读写‘,GETDATE() ‘记录时间‘FROM sys.dm_exec_procedure_stats AS aCROSS APPLY sys.dm_exec_sql_text(a.sql_handle)  bCROSS APPLY sys.dm_exec_query_plan(a.plan_handle) c where database_id=7ORDER BY a.total_elapsed_time / a.execution_count  DESC;GO

 

5.前50存储过程情况：

SELECT TOP 50 a.database_id 数据库 , OBJECT_NAME(object_id, database_id) 存储过程, a.total_elapsed_time/a.execution_count AS [平均时间],a.execution_count 执行次数,a.total_physical_reads/a.execution_count ‘平均物理读写时间‘,a.total_logical_writes/ a.execution_count ‘平均逻辑读写‘FROM sys.dm_exec_procedure_stats AS aCROSS APPLY sys.dm_exec_sql_text(a.sql_handle)  bCROSS APPLY sys.dm_exec_query_plan(a.plan_handle) cwhere database_id=7ORDER BY a.total_elapsed_time / a.execution_count  DESC;GO
