Thread: Select case

Select case

From
"Chad Thompson"
Date:
I want to be able to change the results that are output from a query like so.
 
select field
from table
if field = 'Stuff' then 'Junk'
elseif field  = 'Crap' then 'Darn'
 
Since I am not quite sure what to look for, I have been unable to find anything in the docs.  Select case doesnt seem to do what I want, but maybe I just dont understand.
 
Thanks
Chad

from table

That'd ought to do what you want.
