Question

update COLORS
set    COLORS.AR = 'RED'
where  COLORS.GCRS = 'FIRST' 
and    (case when max(NEWAPP."AGE") > 60 
and    count(NEWAPP."AGE") > 0)

I get an error that says “group function is not allowed here”

Does anyone know what I can do to prevent this error?

The title pretty much says everything I can about the objective.

Answer 1

If there really is no relationship between the tables

UPDATE colors
   SET colors.ar = 'RED'
 WHERE colors.gcrs = 'FIRST'
   AND EXISTS( SELECT 1
                 FROM newapp
                WHERE age > 60 )

It would be very unusual, though, in a proper data model to have a situation where you want to do an uncorrelated subquery like this. Normally, there would be some column that relates the colors table to the newapp table and you would want an additional predicate in the EXISTS subquery for that relationship.
