Combining Rows in a SQL Query

Hi
I would like to find out if it is possible via a SQL query to do something like this:
given a invoice -- invoice item table structure have a SQL query show me something like

Invoice Products
---------- ---------------

1012        a,b,c,d
1013        a,e,f

this input table would be some thing like

Invoice Produc
t
---------- ------------

1012      a
1012      b
1012      c
1012      d
1013      a
1013      e
1013      f

does anybody know who to do this without using a cursor in PL/SQL ???

Thank you
