在SQL Server数据库中,如何才能查看SQL语句的执行时间呢?本文将为您介绍查询方法,供您参考,希望对您能够有所帮助。
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
?
?
3:
SET STATISTICS io ON
SET STATISTICS time ON
go
执行语句
go
SET STATISTICS profile OFF
SET STATISTICS io OFF
SET STATISTICS time OFF
