MySQL INSERT INTO ... VALUES 和 SELECT

MySQL INSERT INTO ... VALUES and SELECT(MySQL INSERT INTO ... VALUES 和 SELECT)

问题描述

有没有办法插入预设值和我从选择查询中获得的值?例如:

Is there a way to insert pre-set values and values I get from a select-query? For example:

INSERT INTO table1 VALUES ("A string", 5, [int]).

我有A string"的值和数字 5，但我必须从这样的选择中找到 [int] 值:

I have the value of "A string" and the number 5, but I've to find the [int] value from a select like this:

SELECT idTable2
FROM table2
WHERE ...

这给了我放在 table1 中的 id.

that gives me that id to put inside table1.

如何将其合并为一个语句?

How to merge this into one statement?

推荐答案

使用 insert ... select 查询，并将已知值放入 select 中:

Use an insert ... select query, and put the known values in the select:

insert into table1
select 'A string', 5, idTable2
from table2
where ...
