[Solved] MYSQL: Search for User ID in one table to search for data in 2 other tables, then show data from all 3 tables


SELECT *
FROM   section_user_map
  JOIN users        USING (UID)
  JOIN verification USING (UID)
WHERE  SectionID = 65
   AND CompleteDate BETWEEN '2012-05-09 12:00:00'
                        AND '2012-05-11 12:00:00'

See it on sqlfiddle.

No UNION required. Outer join would only be required if you still want to return results for users who do not exist in one (or both) of the users or verification tables.
