Arrrgh，我没有得到这个。
我有一张来自 Dynamics GP 的帐户表，它有 7 列。我需要为给定月份没有任何活动的帐户填写空白月份。
我创建了一个内存表@MONTHS，其中包含如下行：
帐户、描述、年份、月份、月份名称、Netchange、PeriodBal
1110000，空，2006，1，空，0，空
这应该与来自 Dynamics GP 的相同信息相匹配。来自 GP 的类似行如下所示：
1110000, 零用现金, 2006, 1, 一月, 15.00, 343.97
如果我们在 2 月份没有花费任何零用现金，那么 2006 年 2 月该帐户将没有任何行，我想将 @MONTHS 表与 DynamicsGP 表进行 RIGHT JOIN 以便填充空白月份。
以下是为便于阅读而缩写的 SQL：
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 永远运行。（即在我失去耐心之前的 5 分钟）
我已经验证了我的@MONTHS 表看起来像我想要的那样。我试过用这两个表做一个“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 表添加该行，Netchange 余额为 0。
感谢您的帮助。完整的 SQL 如下。
