Question

Arrrgh，我没有得到这个。

我有一张Dynamics GP的帐户表，其中有7列。对于某个月没有任何活动的帐户，我需要填写空白月份。

我创建了一个内存表@MONTHS，其行如下：

帐户，说明，年份，月份，月份名称，Netchange，PeriodBal

1110000，NULL，2006,1，NULL，0，NULL

这应该与来自Dynamics GP的相同信息相匹配。 GP的类似行似乎如下：

1110000，Petty Cash，2006,1，January，15.00,343.97

如果我们在2月没有花费任何小额现金，那么在2006年2月就没有该帐户的行，我想用DynamicsGP表制作@MONTHS表RIGHT JOIN，以便填补空白月份。

这是为缩短可读性而缩短的缩写：

SELECT Z.GPACCOUNTNO, 
Z.DESCRIPTION, 
Z.FISCALYEAR, 
Z.FISCALPERIOD, 
Z.FISCALPERIODNAME, 
Z.NETCHANGE, 
Z.PERIODBALANCE
FROM Z
RIGHT JOIN @MONTHS M 
    ON Z.GPACCOUNTNO = M.GPACCOUNTNO
    AND Z.FISCALPERIOD = M.FISCALPERIOD
    AND Z.FISCALYEAR = M.FISCALYEAR

SQL只会永远运行。（即在我失去耐心之前5分钟）

我已经确认我的@MONTHS表看起来像我打算。我已经尝试用两个表做一个“UNION ALL”，它给了我重复。

如果表Z没有给定帐户/年/月的当前行，我希望我的@MONTHS表添加Netchange余额为0的那一行。

感谢您的帮助。完整的SQL如下所示。

Answer 1

您可以在null

时使用SQL case语句进行连接

CREATE TABLE #TMP
(
    id int,
    [month] datetime
)
INSERT INTO #TMP(id,[month])values(1,GETDATE())
INSERT INTO #TMP(id,[month])values(2,null)
INSERT INTO #TMP(id,[month])values(3,GETDATE())
INSERT INTO #TMP(id,[month])values(4,GETDATE())

CREATE TABLE #TMP2
(
    id int,
    [month] datetime
)
INSERT INTO #TMP2(id,[month])values(1,GETDATE())
INSERT INTO #TMP2(id,[month])values(2,GETDATE())
INSERT INTO #TMP2(id,[month])values(3,GETDATE())
INSERT INTO #TMP2(id,[month])values(4,GETDATE())

select * from #TMP
select * from #TMP2


SELECT #TMP.[id], case when #TMP.[month] is null then #TMP2.[month] else #TMP.month end
from #tmp
inner join #tmp2 on #tmp.id= #tmp2.id

drop table #tmp,#tmp2

Answer 2

为什么不使用@Months表作为起点（因为它已经为您提供了所需的所有月份）并填写Z中的值（如果可用）？

SELECT 
M.GPACCOUNTNO, 
M.DESCRIPTION, 
M.FISCALYEAR, 
M.FISCALPERIOD, 
M.FISCALPERIODNAME, 
ISNULL(Z.NETCHANGE, 0) as NETCHANGE
ISNULL(Z.PERIODBALANCE, 0) as PERIODBALANCE
FROM @MONTHS M
LEFT JOIN Z
    ON Z.GPACCOUNTNO = M.GPACCOUNTNO
    AND Z.FISCALPERIOD = M.FISCALPERIOD
    AND Z.FISCALYEAR = M.FISCALYEAR

SQL右键加入？
