Not quite clear to me the rule that you want to use - can you give this a try?

;with cte as
( select *, row_number() over (partition by field1 order by case when field2 = 0 then 0 else 1 end) as RN
from YourTable
)
select field1,field2 from cte where RN = 1;

Thank You - looks very complicated
should be simpler method
i want to exclude the combination of field1:25 & field2:0 = (250)
but return everything else

Apologies - i was being silly

where ((field2 <> 0 and field 1= 25)
or (field2= 0and field1 <> 25)
or (field2<> 0 and field1 <> 25))

Thank You ALL

you just need this


WHERE CASE WHEN field1 = 25 AND field2 = 0 THEN 0 ELSE 1 END = 1
