不知道各位大侠还有其他的什么好方法能实现吗？

Question

大家好，我有一个数据表（如表1所示），我想对每个站在开始时间和结束时间之间插入时间段，步长为1天，得到的结果应该为表2所示，表1结构如下站名 开始时间 结束时间s1 1980-1-1 1980-2-1s2 1992-2-1 1993-3-1表2站名 时间s1 1980-1-1s1 1980-1-2s1 1980-1-3................s1 1980-2-1s2 1992-2-1s2 1992-2-2..........s2 1993-3-1我自己编了一个表函数，但是调用函数时怎么才能把各个站点的参数传递到函数里呢？谢谢各位大侠了--@tminit是开始时间，@tmend是结束时间，TM是时间CREATE FUNCTION CaculateDailyTM(@STCD char(8),@tminit datetime,@tmend datetime)returns @mytbl table (STCD char(8),TM datetime)asbegindeclare @temptm datetimeset @temptm=@tminitwhile @temptm<=@tmendbegininsert into @mytbl select STCD,@temptmset @temptm=@temptm+1endreturnRETURNendGO

这个问题用标致函数比较难，1楼调用标致函数的方法也是错误的，正确的方法应该是：
SELECT * FROM DBO.CaculateDailyTM（）

我用游标实现 ，比较好理解：

create table tb1(zm char(8),sd datetime,ed datetime)
GO
insert into tb1 values('s1','1980-1-1','1980-2-1')
insert into tb1 values('s2','1992-2-1','1993-3-1')
GO
--建立测试数据

declare zm_cursor cursor fast_forward for select zm from tb1
declare @t1 datetime,@t2 datetime,@zm char(8)
declare @tb table(zm char(8),d datetime)
open zm_cursor
fetch next from zm_cursor into @zm
while @@fetch_status=0
begin
select @t1=sd,@t2=ed from tb1 where zm=@zm
while @t1<=@t2
begin
insert into @tb values(@zm,@t1)
set @t1=dateadd(day,1,@t1)
end
fetch next from zm_cursor into @zm
end
select * from @tb
close zm_cursor
deallocate zm_cursor

GO

DROP TABLE TB1
