That the right side of the BinaryTupleExpression owns columns is not supported for / while executing SQL:
"select a."member_num", b."member_num_tb", a."member_num" / b."member_num_tb" from ( select count(distinct mobile) as "member_num" ,'week' as "dtype" from member where dweek <= '18.06.04~18.06.10' ) as a left outer join ( select count(distinct mobile) as "member_num_tb" ,'week' as "dtype" from member where dweek_tb <= '18.06.04~18.06.10' ) as b on a."dtype" = b."dtype" "
请问这是是什么原因啊？
