Question

如果我只是查询主表OEINDLID，我将只获得一半的行。

即使执行此查询/ 400也会返回重复项，我该如何解决此问题？

SELECT T01.IDORD#, T01.IDDOCD, T01.IDPRT#, T01.IDSHP#, T01.IDNTU$,
       (IDNTU$*(IDSHP#)) AS LINTOT, T02.IAPTWT, T02.IARCC3, T03.MHSTAT, T03.MHZONR,
       T03.MHSHIN, T01.IDORDT, T01.IDHCD3
FROM ASTDTA.OEINDLID T01 INNER JOIN
     ASTDTA.ICPRTMIA T02 
     ON T01.IDPRT# = T02.IAPRT# INNER JOIN
     astdta.MFHHMHPK T03
     ON T01.IDORD# = T03.MHORDP
WHERE  IDHCD3 in ('MDL','TRP')

所需数据是：

但是当我们在连接处添加我们想要的部分#data（重量等）然后加载运输数据时我们得到这个：

 04662926    20,140,116   CRDGBOX                     250.00            .650000                       162.50000000          .02000
 04662926    20,140,116   CRDGBOX                     250.00            .650000                       162.50000000          .02000
 04662926    20,140,116   CRDGBOX                     250.00            .650000                       162.50000000          .02000
 04662926    20,140,116   CRDGBOX                     250.00            .650000                       162.50000000          .02000

你可以在CRDGBOX部分的例子中看到我们有2个上面但是4这里有一个内部连接。

Answer 1

尝试SELECT DISTINCT：

INNER JOIN (SELECT DISTINCT
               MHORDP, MHSTAT, MHZONR, MHSHIN
             FROM ASTDTA.MFHHMHPK) AS T03 ON T01.IDORD# = T03.MHORDP

SQL查询从AS / 400服务器返回重复项
