Question

I have two tables – Table1:

id  name  number
------------------
1   x1    123
2   x2    234

…and Table2:

tbl1id  title  rank
--------------------
1       t1      3
1       t2      2
2       t1      3
1       t3      1

Is there a way I can join them to return result as showing max title based on min rank for given user:

id  name  number  max_title  rank
----------------------------------
1   x1    123     't3'        1
2   x2    234     't1'        3

Answer 1

Use:

   SELECT t.id,
          t.name,
          t.number,
          COALESCE(x.max_title, 'no title associated') AS max_title
     FROM TABLE1 t
LEFT JOIN (SELECT t2.tbl1id,
                  MAX(t2.title) 'max_title'
             FROM TABLE2 t2
            WHERE t2.rank = (SELECT MIN(rank) 
                               FROM TABLE2 
                              WHERE tbl1id = t2.tbl1id)
         GROUP BY t2.tbl1id) x ON x.tbl1id = t.id
