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 ?
