可以用以下语句统计数据库的性能,需要注意的是必须用管理员的权限打开数据库才可以执行。
declare @n int set @n=30
;with maco as ( select top (@n) plan_handle, sum(total_worker_time) as total_worker_time , sum(execution_count) as execution_count , count(1) as sql_count from sys.dm_exec_query_stats group by plan_handle order by sum(total_worker_time) desc ) select t.text , a.total_worker_time , a.execution_count , a.sql_count from maco a cross apply sys.dm_exec_sql_text(plan_handle) t
