SQL：如何使用 MariaDB 中的连接使用来自另一个表的数据更新一个表

Question

I am pretty new to SQL. I am trying to update one table with the data from another.

Table1: albums

album_id
user_id   -   correct value

Table2: images

image_id
album_id
user_id  -  wrong value

I need to update images.user_id with data from albums.user_id where albums.album_id = images.album_id

Answer 1

You can use an update / join :

update images i join
       albums a
       using (album_id)
     set i.user_id = a.user_id;
