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_plan FROM sys.dm_exec_procedure_stats AS a CROSS APPLY sys.dm_exec_sql_text(a.sql_handle) b CROSS APPLY sys.dm_exec_query_plan(a.plan_handle) c ORDER 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 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;
3.前50存储过程语句：
create view procname_view as 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‘, GETDATE() ‘记录时间‘ FROM sys.dm_exec_procedure_stats AS a CROSS APPLY sys.dm_exec_sql_text(a.sql_handle) b CROSS APPLY sys.dm_exec_query_plan(a.plan_handle) c where database_id=7 ORDER 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 a CROSS APPLY sys.dm_exec_sql_text(a.sql_handle) b CROSS APPLY sys.dm_exec_query_plan(a.plan_handle) c where database_id=7 ORDER BY a.total_elapsed_time / a.execution_count DESC; GO
