【问题描述】：

我需要一些帮助。我试过了，但它不起作用。我选择了我需要的所有数据并试图说出没有的数据原始文件。

谁能告诉我正确的方法？

 SELECT * 
    FROM acknowledgement t1
    where t1.st01 = '110' 
    and (t1.shipment ='S640D14268424' or t1.Shipment ='S640D14268924' or
      t1.Shipment ='S640D14268925' or t1.Shipment ='S646D14261190' or
      t1.Shipment ='S646I14265886' or t1.Shipment ='S640D14268423' ...)
   AND [shipment] 
   NOT IN(
   SELECT [shipment] FROM acknowledgement 
   )

任何帮助都会很有用。

【问题讨论】：

什么 ru 试图实现..你的最后一个条件是选择所有未确认发货的行......并且你从同一个表中获取数据..所以它总是没有记录跨度>
我选择了一些不在表格中的记录。我想尝试查找该表中不存在的相同记录，而不是一次执行 1 个。
你可以说t1.Shipment in ('S640D14272953', 'S640D14276996' ... )，它也一样，字符更少，看起来更好。
如何在确认表中找到不在查找确认表中的货件？
你应该改进你的问题。你在做什么，你希望得到什么？

更好的方法是创建一个临时表来存储您要检查的数字。

【讨论】：

那个例子看起来不错，我复制了它并尝试了它，但没有成功。我知道前 5 条记录不存在，而其他一些记录存在。那至少应该向我展示前 5 条记录。但是当我运行这个示例时，它发现 0 。
您的确认表中是否有空货件值？如果是这样，请在第二个子查询中添加 WHERE Shipment>''（或 IS NOT NULL）。
