this will give you a max for each condition where the group by fields are
different:
select field1, field2, feidl3, max(field4) from table1 group by
field1,field2,field3;
to specify only a particular record:
select field1, field2, field3, max(field4)
from table1
where field1 = somefield1value
and field2 = somefield2value
and field3 = somefield3value
group by field1,field2,field3;
give this a try. hope it helps
