【问题描述】：

我已经构建了以下查询，但是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告诉我哪里出了问题吗？

查询：

))

【参考方案1】：

由于您的from 子句中没有名为case_master 的表，因此您不能在您的where 子句中使用它。

【讨论】：

嗨，它应该是这样的：SELECT DISTINCT case_event_assess.case_id FROM case_event ce, case_event_assess, lm_datasheet, case_product cp, case_assess ca, case_master

我尝试将 case_master 添加到 from 子句，但现在又遇到了另一个错误：ORA-00979: not a GROUP BY expression 00979. 00000 - “not a GROUP BY expression” *原因：*行动：行错误：72 列：10

对于我收到的第二个错误。我通过执行以下操作更正了它：修改了这个：SELECT DISTINCT case_event_assess.case_id、case_master.followup_date 和分组方式：使用这个：GROUP BY case_event_assess.case_id、case_event_assess.event_seq_num、case_event_assess.prod_seq_num、case_master.followup_date 现在查询正在运行.行。感谢您的提示 piet.t
