RE: SQL Select Case Then Group By

[<Rick.Chevalier@xxxxxxxxxxxxxxx>]

Michael,

Birgitta's solution is probably the simplest.  However, I think you
could also substitute 1 for the group by value.  This will use the first
field selected as the grouping field.

 SELECT Case
           When STUNNO = 11111 then 'INTERNET'
           When STUNNO = 22222 then 'CORPORATE'
           ELSE 'ALL RESTAURANTS'
        end
 from MYFILE
 GROUP BY 1
