大家好，我有一個數(shù)據(jù)表（如表1所示），我想對每個站在開始時間和結(jié)束時間之間插入時間段，步長為1天，得到的結(jié)果應(yīng)該為表2所示，表1結(jié)構(gòu)如下站名開始時間結(jié)束時間s1 1980-1-1 1980-2-1s2 1992-2-1 1993-3-1表2站名時間s1 1980-1-1s1 1980-1-2s1 1980-1-3................s1 1980-2-1s2 1992-2-1s2 1992-2-2..........s2 1993-3-1我自己編了一個表函數(shù)，但是調(diào)用函數(shù)時怎么才能把各個站點的參數(shù)傳遞到函數(shù)里呢？謝謝各位大俠了--@tminit是開始時間，@tmend是結(jié)束時間，TM是時間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

這個問題用標(biāo)致函數(shù)比較難，1樓調(diào)用標(biāo)致函數(shù)的方法也是錯誤的，正確的方法應(yīng)該是：
SELECT * FROM DBO.CaculateDailyTM（）

我用游標(biāo)實現(xiàn) ，比較好理解：

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
