sql - 插入多个子查询作为值

Question

让我们假设我必须将一个具有许多fk的表插入到表中，仅在下面错误语句下方进行解释:

insert into mytable
values
(
somevalue
,somevalue
,select id from othertable1 where ...condition
,select id from othertable2 where ...condition
,select id from othertable3 where ...condition
)

因此，基本上要插入的值来自不同的子查询，是否有可能实现这种行为？

Answer 1

insert into mytable (columns)
select somevalue, somevalue, a.id, b.id, c.id
from
 othertable1 a
 cross join othertable2 b
 cross join othertable3 c
where
 a ... condition
 b ... condition
 c ... condition
