    If the condition really looks like that (same table, only one field different in the groups):

    select opp, count(*) from tablename
    where date = 'BAZ'
    group by opp
    having opp in ('FOO', 'BAR');
    

    For arbitrary queries:

    select 'A', count(*) from tableA
    union all
    select 'B', count(*) from tableB
