如果sales id的其中一行没有acknumber值，我想删除一个salesid。上面的正确结果仅为SO-0461621。

SELECT sal.SALESID , 
       lne.PURCHID , 
       lne.ACKNUMBER , 
       lne.CONFIRMEDDLV
  FROM
       SALESTABLE Sal LEFT JOIN SALESLINE SalLne ON Sal.SALESID = SalLne.SALESID
                      LEFT JOIN PURCHLINE Lne ON Lne.INVENTTRANSID = SalLne.INVENTREFTRANSID
  WHERE SalLne.INVENTREFID LIKE 'PO%'
    AND sal.SALESSTATUS IN( 0 , 1 )
    AND sal.SALESPOOLID <> 'FURN-CONF'
    AND sal.DLVMODE LIKE 'FURN%';

Answer 1

SELECT sal.SALESID , 
       lne.PURCHID , 
       lne.ACKNUMBER , 
       lne.CONFIRMEDDLV
  FROM
       SALESTABLE Sal LEFT JOIN SALESLINE SalLne ON Sal.SALESID = SalLne.SALESID
                      LEFT JOIN PURCHLINE Lne ON Lne.INVENTTRANSID = SalLne.INVENTREFTRANSID
  WHERE SalLne.INVENTREFID LIKE 'PO%'
    AND sal.SALESSTATUS IN( 0 , 1 )
    AND sal.SALESPOOLID <> 'FURN-CONF'
    AND sal.DLVMODE LIKE 'FURN%'
    and not sal.SALESID in (select SALESID from SALESTABLE where ACKNUMBER   is null);

您不需要进行子查询，只需在WHERE子句中添加另一个条件

SELECT sal.SALESID , 
   lne.PURCHID , 
   lne.ACKNUMBER , 
   lne.CONFIRMEDDLV
FROM
   SALESTABLE Sal LEFT JOIN SALESLINE SalLne ON Sal.SALESID = SalLne.SALESID
                  LEFT JOIN PURCHLINE Lne ON Lne.INVENTTRANSID = SalLne.INVENTREFTRANSID
WHERE SalLne.INVENTREFID LIKE 'PO%'
  AND sal.SALESSTATUS IN( 0 , 1 )
  AND sal.SALESPOOLID <> 'FURN-CONF'
  AND sal.DLVMODE LIKE 'FURN%';
  AND Lne.ACKNUMBER IS NOT NULL

另外，您在帖子中说，应该返回的唯一数据是＆＃34; SO-0461621＆＃34;然而它看起来像＆＃34; SO-0446950＆＃34;在ACKNUMBER中也有一个有效值......如果这两个SALESID都被退回了吗？希望这有帮助！
