我有两张桌子用于merge。我的查询有问题，我找不到任何关于原因的信息。会发生什么;我将运行查询，它工作正常，因为我的目标表填充了我想要的信息。然后我再次运行查询（紧接其后）并更改（38行受影响）我再次运行它并将行添加回来 - 再次...行被删除。有超过100行但似乎只有相同的行受到影响。源表中没有任何变化。
我怀疑我在DELETE上执行了WHEN MATCHED - 我只能找到DELETE WHEN NOT MATCHED的信息 - 但我不知道，因为这似乎只会影响到MERGE QA.dbo.RMA AS target USING Touchstn02.dbo.RMA_Detail AS source
ON (target.RMANUM_52 = source.RMANUM_52)
WHEN MATCHED AND (source.STATUS_52 >3)
THEN
DELETE
WHEN NOT MATCHED AND (source.STATUS_52 < 4) AND (source.RECQTY_52 > 0)
THEN
INSERT (RMANUM_52, RMADATE_52, CUSTID_52, RETNUM_52, RETQTY_52,
SERIAL_52, REPAIR_52,
RPLACE_52, CREDIT_52, WRKNUM_52, KEYWRD_52, RECQTY_52,
RECDTE_52, STATUS_52,
REM1_52, REM2_52, REM3_52, Comment, CMPDTE)
VALUES (source.RMANUM_52, source.RMADTE_52, source.CUSTID_52,
source.RETNUM_52,
source.RETQTY_52, source.SERIAL_52, source.REPAIR_52,
source.RPLACE_52, source.CREDIT_52,
source.WRKNUM_52, source.KEYWRD_52, source.RECQTY_52,
source.RECDTE_52,
source.STATUS_52, source.REM1_52, source.REM2_52,
source.REM3_52, source.REM4_52,
source.CMPDTE_52);
每次38行。

与往常一样，我感谢任何帮助/输入

我想我已经得到了它！
要删除的38行在源表中至少有两个STATUS_52值，用于这些RMANUM_52键值。
对于给定的RMANUM_52键值：
因此，在第一次运行时，插入一行STATUS_52值＆lt; 4。
然后在下一次运行DELETE时触发，因为匹配是由RMANUM_52和SOURCE表中的STATUS_52进行的。这里棘手的是我们正在回顾源表中所有行的状态值（包括不属于第一个插入的行）。并且源表中有一个不同的行，它将RMANUM_52与STATUS_52＆gt;匹配。 3.所以DELETE逻辑匹配和删除发生。
我无法从你的例子中确切地知道你的要求是什么，所以我不会冒险猜测修复。
