I do believe the "count distinct" will address that.

Is ottrnc a unique field? He's looking for sets that have both CVC and
GRE. Could there be two CVC's?


You're thinking too hard. All you need is.

SELECT otord#
from astccdta.oetra99
where ottrnc in ('CVC', 'GRE')
group by otord#
having count(distinct ottrnc) = 2
