下面这种是SQL Server中比较简单的查询SQL语句执行时间方法,通过查询前的时间和查询后的时间差来计算的:
declare @begin_date datetime
declare @end_date datetime
select @begin_date = getdate()
<这里写上你的语句...>
select @end_date = getdate()
select datediff(ms,@begin_date,@end_date) as '用时/毫秒'
2:下面这种方法比较全面,将执行每个语句时采取的步骤作为行集返回,通过层次结构树的形式展示出来
set statistics profile on
set statistics io on
set statistics time on
go
<这里写上你的语句...>
go
set statistics profile off
set statistics io off
set statistics time off
存储过程执行时间
declare @begin_date datetime declare @end_date datetime select @begin_date = getdate()
你的存储过程
select @end_date = getdate() select datediff(ms,@begin_date,@end_date) as '用时/毫秒'
