At least that way you can provide a working query that others can look at and know exactly what you need. In this case you have a single table and want the result to have more rows than the input - I'm not sure how anything but a union will accomplish that goal. You have to generate those rows somehow. There may be better ways of looking at your problem but you only gave us a toy model to play with. David J.
