SQL的重复数据为Exceldynamic表
首先感谢您阅读我，并为我的英语不好而感到抱歉。
我在sql server 2008 r2上有下面的代码
SELECT FA960.*, UMCONVPZ.UMFR, UMCONVPZ.UMCONF AS Piezas, UMCONVPL.UMCONF AS PL, UMCONVCJ.UMCONF AS Cajas FROM FA960 FA960 JOIN UMCONV UMCONVPZ ON FA960.RECURV = UMCONVPZ.UMRESR JOIN UMCONV UMCONVPL ON FA960.RECURV = UMCONVPL.UMRESR JOIN UMCONV UMCONVCJ ON FA960.RECURV = UMCONVCJ.UMRESR WHERE FA960.RMUMSR = UMCONVPZ.UMFR AND UMCONVPZ.UMTO = 'PZ' AND UMCONVPL.UMTO = 'PL' AND UMCONVCJ.UMTO = 'CJ' 输出：

这是一个观点，UMCONV表是一个转换的措施，从小盒子到盒子，片断。
现在我的问题是，CJ（箱）去PZ（件）和PL（小吃），从而使我成为“垃圾数据”的重复条目。

任何想法如何解决？ 到目前为止，我认为迫使它转换，并做一个石头剪刀
任何其他的想法？
这是
这对你如何工作：
SELECT DISTINCT f.*, f.RMUMSR as De, COALESCE((SELECT UMCONF FROM UMCONV WHERE UMRESR = f.RECURV AND UMFR = f.RMUMSR AND UMTO = 'PZ'), 1) AS Piezas, COALESCE((SELECT UMCONF FROM UMCONV WHERE UMRESR = f.RECURV AND UMFR = f.RMUMSR AND UMTO = 'PL'), 1) AS Palet, COALESCE((SELECT UMCONF FROM UMCONV WHERE UMRESR = f.RECURV AND UMFR = f.RMUMSR AND UMTO = 'CJ'), 1) AS Cajas FROM FA960 f
你有没有尝试过使用DISTINCT：
SELECT DISTINCT FA960.*, UMCONVPZ.UMFR, UMCONVPZ.UMCONF AS Piezas, UMCONVPL.UMCONF AS PL, UMCONVCJ.UMCONF AS Cajas FROM FA960 FA960 JOIN UMCONV UMCONVPZ ON UMCONVPZ.UMRESR = FA960.RECURV AND UMCONVPZ.UMFR = FA960.RMUMSR AND UMCONVPZ.UMTO = 'PZ' JOIN UMCONV UMCONVPL ON UMCONVPL.UMRESR = FA960.RECURV AND UMCONVPL.UMTO = 'PL' JOIN UMCONV UMCONVCJ ON UMCONVCJ.UMRESR = FA960.RECURV AND UMCONVCJ.UMTO = 'CJ'
不知道更多的数据很难说。
