测试sql语句执行时间

测试sql语句执行时间，备档用的

新建表：pagetest

--添加数据

declare @i int

set @i=0

while(@i<90000)

begin    

insert into pagetest select cast(floor(rand()*10000) as int),left(newid(),10),getdate()    

set @i=@i+1

end



--测试速度

declare @begin_date datetime

declare @end_date datetime

declare @tab table(id int)

select @begin_date = getdate()





--exec sql

select @end_date = getdate()

select datediff(ms,@begin_date,@end_date) as '毫秒'
