我正在使用PL / SQL(Oracle)。 我以前写过查询,但我不确定这个查询有什么问题。我得到的错误是:
[错误]执行(942:41): ORA-00979:不是GROUP BY表达式。
突出显示的文本是:case语句中的第一个TRIM函数。我知道我不能将这个case语句放在Group By子句中,因为我在这里聚合(使用sum函数)。有什么我不理解的吗?

答案 0 :(得分:4)
您的问题是您尝试在分组上下文中访问非aggragate(LOBDESC
)。您有两种选择,选择最有意义的选项:
LOBDESC
添加到GROUP BY
MAX(LOBDESC)
答案 1 :(得分:2)
使用Oracle,在分组时,您只能选择:
GROUP BY
子句中出现的字段COUNT
,SUM
等)您的CASE
子句将被重写。也许,为了您的目的使用分析函数会更好:
答案 2 :(得分:2)
您必须将LOBDESC
添加到GROUP BY
列列表中,因为您在聚合函数外的select
中使用它。
