MySQL JOIN with IF conditions

Question

I want to get some results via query simillar to:

SELECT 
    * FROM
    users LEFT JOIN
    IF (users.type = \'1\', \'private\',\'company\') AS details ON
          


        

Answer 1

SELECT
  users.*,
  details.info,
  CASE users.type WHEN '1' THEN 'private' ELSE 'company' END AS user_type
FROM
  users
  INNER JOIN (
    SELECT user_id, info FROM private
    UNION
    SELECT user_id, info FROM company
  ) AS details ON details.user_id = users.id

---

EDIT: Original version of the answer (question misunderstood):

SELECT
  *, 
  CASE type WHEN '1' THEN 'private' ELSE 'company' END AS details
FROM
  users
WHERE
  users.id = 1
