mysql - 连接时 SQL 未知列

Question

当我尝试运行以下命令时，出现错误“'字段列表'中的未知列'guests_guest.id'”:

SELECT guests_guest.id
FROM `guests_guest` full join
guests_guest_group
on guests_guest.id=guests_guest_group.guest_id

所有的列名和表名都是正确的。事实上，运行只是

SELECT guests_guest.id
FROM `guests_guest`

工作正常。我怀疑我缺少语法问题。我做错了什么？

Answer 1

尝试:

SELECT gg.id
FROM `guests_guest` as gg
join guests_guest_group as ggg
on ggg.guest_id=gg.id

假设 guests_guest_group 没有 id 列。
