I am guessing that you want to show "No" if the value is 0 and "Yes" otherwise for months field. If the assumption is correct then check the query for the same. I have done it for only one field do to same for other fields as well.
select StateName, DistrictName,BlockName,
case when Jan > 0 Then 'Yes' else 'No' end JAN,
