看一个简单的实例
create procedure order_tot_amt @o_id int, @p_tot int output as select @p_tot = sum(unitprice*quantity) from orderdetails where ordered=@o_id go下面来看一个利用存储过程批量导入数据实例
declare @mycounter int
set @mycounter = 0 /*设置变量*/
while (@mycounter < 2) /*设置循环次数*/
begin
waitfor delay '000:00:10' /*延迟时间10秒*/
insert into time_by_day
(time_id, the_date, the_year, month_of_year, quarter, day_of_month)
select top 1 time_id + 1 as time_id, the_date + 1 as the_date, year(the_date + 1)
as the_year, month(the_date + 1) as month_of_year, { fn quarter(the_date + 1)
} as quarter, day(the_date + 1) as day_of_month
from time_by_day
order by time_id desc
set @mycounter = @mycounter + 1
end
