测试sql语句执行时间

--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'
