查看SQL语句在SQL Server上的执行时间,方便大家监控语句的性能。写出更好的代码。
1:下面这种是比较简单的查询方法,通过查询前的时间和查询后的时间差来计算的 代码如下:
declare @begin_date datetime
declare @end_date datetime
select @begin_date = getdate()
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
代码如下:
set statistics profile on
set statistics io on
set statistics time on
go
go
set statistics profile off
set statistics io off
set statistics time off
