Question

如何为这个select语句创建一个insert语句？

SELECT et 
 FROM user 
      inner join  petrazafa.class_room 
      using(id) 
where title like '%11%' 
   or  title like '%12%';

我需要插入所有et = 1;

感谢

Answer 1

编辑1：

我认为这里有一个答案：Use select query inside the Insert query for the same table name

对你：

INSERT INTO `yourtable`(et)
SELECT et 
FROM user 
      inner join  petrazafa.class_room 
      using(id) 
 where title like '%11%' 
      or  title like '%12%';

观看文档：

INSERT ... SELECT Syntax

Doc Exemple：

INSERT INTO tbl_temp2 (fld_id)
SELECT tbl_temp1.fld_order_id
FROM tbl_temp1 WHERE tbl_temp1.fld_order_id > 100;

Answer 2

尝试类似

的内容

  INSERT INTO user( 1 as et )
SELECT et
    FROM user 
      inner join  petrazafa.class_room 
      using(id) 
where title like '%11%' 
   or  title like '%12%';

Answer 3

据我了解，您想更新et=1

的title like '%11%' or title like '%12%'

表示

update user u inner join petrazafa.class_room  c on u.id=c.id set et=1  where title like '%11%' 
or title like '%12%'

插入与内连接的组合
