SQL Server如何查看SQL语句的执行时间

1)较为简单

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)字段较多，比较复杂

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
