Question

如果返回不同，有人可以查看我的查询并提供帮助。我试图使用不同的值获取父表和子表中的所有值，并且可能没有链接和没有链接的记录

Create table Parent(Parentid VARCHAR(10), parentname varchar(15))

Insert into Parent 
values (1, 'parent'), (2, 'parent2'), (3, 'parent3')

create table child
(
     childid VARCHAR(10), 
     childname varchar(15),
     parentfatherid VARCHAR(10), 
     parentmotherid VARCHAR(10)
)

insert into child
values  (10, 'child1', 1, null),
        (20, 'child2', null, null),
        (30, 'child3', 2, null),
        (40, 'child4', 1, null),
        (50, 'child5', 2, null),
