我有一张这样的桌子
column1 column2 column3
abc xyz 4
def ghi 3
abc xyz 6
abc xyz 1
jkl mno 4
查询后的预期结果
column1 column2 column3
abc xyz 11
def ghi 3
jkl mno 4
我的查询如下:
select column1, column2, count(column3)
from
(select ......) as column1,
(select ......) as column2,
(select ......) as column3)
group by column1, column2, count(column3)
我收到此错误“不是单组组功能”
