insert into with combination of inner join

问题

How can I make an insert statement of this select statement?

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

I need to insert into all et = 1;

thanks

Edit 1 :

I think there's an answer here : Use select query inside the Insert query for the same table name

For you :

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

Watch doc :

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;

Try something like

  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%';

As I understand you want to update et=1 for title like '%11%' or title like '%12%'

for that

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%'
