我有一个members_info表，里面有很多成员，但我需要做的是用成员A的信息更新成员B的信息。
以下是成员用户ID：
会员A = 98089（member_info_id）
成员B = 236505（member_info_id）
这两个成员没有任何共同点，所以我不能加入。如何更新会员B的信息？
这是表的结构，但我怀疑它是否有用

即使它们没有直接关联，您仍然可以执行JOIN：
UPDATE
members_info mb JOIN
members_info ma ON ma.member_info_id = 98089
SET
mb.Name = ma.Name,
mb.Info = ma.Info
-- Etc...
WHERE
mb.member_info_id = 236505

如果您只想用A的信息更新单个成员（B），那么......
UPDATE members_info member_B, (SELECT DISTINCT ID, Column_1, Column_2, Column_X
FROM members_info
WHERE id = '98089') member_A
SET member_B.Column_1 = member_A.Column_1, member_B.Column_2 = member_A.Column_2
WHERE member_B.id = '236505'
