sql - Teradata 错误 3782 联接表的搜索条件中的列引用不正确

Question

我对我继承的一些 sql 进行了一些更改(在下面突出显示)，并且我得到了

Error 3782 Improper column reference in the search condition of a joined table

我不知道为什么我会收到这条消息。任何帮助将不胜感激。

您混合了新旧风格的连接语法。如果您遵循以下简单规则，您的问题将永远不会存在:永远不要使用逗号 FROM条款。始终使用显式 JOIN句法。

问题是逗号运算符周围的范围。虽然它在功能上等同于 CROSS JOIN ，第一部分不是第二部分的已知别名。

如果您修复 FROM删除所有逗号，您的问题将得到解决，即使您只将逗号更改为 CROSS JOIN .但是，我建议使用正确的 JOIN .
