插入多个子查询作为值 [英] Insert into with multiple subqueries as values

问题描述

假设我必须插入一个有很多 fk 的表，只是为了在下面解释错误的陈述:

Lets suppose I've to insert into a table with many fk, just to explain here below the wrong statement:

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

所以基本上要插入的值来自不同的子查询，是否有可能实现这样的行为?

so basically values to insert comes from different subqueries, is it possible to achieve such a behavior ?

推荐答案

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
