1919    email@DOMAIN.COM         SOME PASSWORD

我希望从这三个
中删除

> user_id and table1. user_id = table3.id

和分组

试试这个。根据表依赖关系删除表中的记录。

i think grouping is not required as you are trying to delete the records


DELETE FROM adl_auth_user 
from adl_auth_user  A 
INNER JOIN user_details  B ON a.user_id=B.user_id
INNER JOIN adl_user  C ON b.user_id=c.id
WHERE A.user_id =1919 AND A.type_id =1

DELETE FROM user_details  
FROM user_details B 
INNER JOIN adl_user C ON b.user_id=c.id
WHERE B.user_id =1919 

DELETE FROM adl_user  
WHERE adl_user .id =1919

从三个表中删除
