title: Ambiguous column name
body: <p>I have the following SQL and it throws the error Ambiguous column name 'id'</p>
  
  <pre><code>select tbl_registration.*, tbl_ebp.name as ebp_name, tbl_Users.id as user_id, tbl_ebp.id as linked_ebp_id
  from tbl_registration
  left outer join tbl_ebp on tbl_ebp.id = tbl_registration.ebp_id
  left outer join tbl_users on tbl_registration.email = tbl_users.username
  where id = [PARAM]p_id
  </code></pre>
  
  <p>I've read some articles on this, but can't find a working solution for my code.
  Any help much appreciated.</p>
