Question

I am struggling to get me head round the MySQL Join function.

Here is two tables I have:

User table:

admin_id     username
  *1          peter93
   2       stackoverflowrocks
   3          user3*

Admin details table:

   admin_username     description        image
       pedro93          [text]        [image_url]
 stackoverflowrocks     [text]        [image_url]
        user3           [text]        [image_url]

I know usualy to link two databases together you would use ID numbers, but in this case I want to join the two tables where admin_username = username.

Can anyone help me please? It is for a PHP script if that helps.

Thanks in advance!
Peter

So that’s fine. You can join on anything you like.

select * 
from user
    inner join admin
    on user.username=admin.admin_username
