我需要检查底部的条件，但由于涉及的（+），我无法更改使用OR。我没有设置那部分，所以我不确定如何重新安排它。有人能告诉我我能做些什么才能让这些条件得以实现？

不要使用旧的FROM TableA,TableB WHERE ...连接语法。只是不要。

相反，请单独写出您的联接：

FROM TableA
INNER JOIN TableB ON ...
LEFT JOIN TableC ON ...

这不仅仅是对旧语法的一般性咆哮：使用新的（我说“新”，但现在已超过20年），标准语法将< / strong>在这种情况下解决您的问题。

在我的WHERE子句中不允许使用OR的外连接运算符 - 错误：ORA-01719
