Sql 为什么会出现错误；ORA-00904：无效标识符“；是否显示在此查询中？

我构建了以下查询，但当我尝试运行它时会引发错误：

ORA-00904: "CASE_MASTER"."FOLLOWUP_DATE":
           invalid identifier 00904. 00000 -  "%s: invalid identifier"
*Cause: 
*Action: Error at Line: 76 Column: 14

你能给我一个提示或者告诉我出了什么问题吗

查询：

由于在您的

from

-子句中没有名为

case\u master

的表，您不能在

where

-子句中使用它。

您好，所以它应该是这样的：从case\u event ce、case\u event\u assessment、lm\u数据表、case\u产品cp、case\u assessment ca中选择不同的case\u-event\u-assessment.case\id，case_master我试图将case_master添加到from子句中，现在我遇到了另一个错误：ORA-00979：不是表达式00979的组。00000-“非表达式分组”*原因：*操作：对于我收到的第二个错误，第72行第10列出现错误。我通过以下操作更正了它：修改了这个：选择不同的case\u event\u assessment.case\u id，case\u master.followup\u date和group by:使用这个：groupby case\u event\u assessment.case\u id，case\u event\u assessment.event\u seq\u num，case\u event\u assessment.prod\u seq\u num，case\u master.followup\u date，现在查询正在运行。好啊谢谢你的小费
