Select grouping ranges of records

I´m designing a new report and I have a query that returns something like :    

   1,2,3,4,5,9,10,11,15,16,17,20,24,25.    

   I need to print this result like this:

   From 1 to 5
   From 9 to 11
   From 15 to 17

        20
   From 24 to 25

   Does anyone have an idea of how can this be done ? Received on Sat Nov 29 2003 - 07:52:22 CST
