Question

我在WHERE过滤器之前使用过JOIN ON，而我很难让它运行。它没有识别别名。我应该以通用的方式提供查询，还是这个问题没有必要？

编辑（加入查询）

您的问题是您在from子句中列出了每个表两次。您可以使用FROM TABLEA，TABLEB ... WHERE表单或FROM TABLEA JOIN TABLEB ON ... WHERE表单，但不要混用它们。

你的FROM子句应该是这样的：

FROM TABLE1 T1 
   JOIN TABLE2
   ON T1.CONTRACTID = T2.CONTRACTID
   JOIN TABLE3
   ON T1.CONTRACTID = T3.CONTRACTID
   JOIN TABLE4
   ON T1.CONTRACTID = T4.CONTRACTID
...
WHERE 
....

我有明天到期的数据，我必须使用12个表才能得到结果
