Hi all

My table definition :

   id | fref      | mref
------+-----------+----------
  1   |     23    |   25
  2   |     24    |   28
  3   |     25    |   31
  4   |     26    |   34

My problem :
i need a query that results in this :

   id |    ref
------+----------
  1   |     23  
  1   |     25
  2   |     24
  2   |     28
  3   |     25   
  3   |     31
  4   |     26   
  4   |     34


Do I need a crosstab-query ?
Who can help me ?
