不是 GROUP BY 表达式 - 聚合函数中的 CASE

Question

我正尝试像往常一样按语句分组，但出现 ORA-00979 错误。运行该脚本需要做什么？感谢您的帮助。错误：00979

Answer 1

您的查询使用 group by 子句，因此您不能 order by 未在此处说明的列（例如 es.EmployeeID），因为这些列实际上不在 [= 的输出中10=] 处理查询期间的子句。

不是 GROUP BY 表达式 - 聚合函数中的 CASE

not a GROUP BY expression - CASE in aggregate function

oracle

group-by

sum
