sql - 为什么在此查询中出现错误 “ORA-00904: invalid identifier”？

Question

我已经建立了以下查询，但是当我尝试运行它会引发错误:

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

您能给我提示还是告诉我什么地方出了问题？

查询:

由于在case_master-子句中没有名为from的表，因此您不能在where-子句中使用该表。
