looking at the query you need something for year where you year= and. What the parser is doing is it is not seeing anything to compare year to so it goes to the next word which is "and" which eliminates your "and" from the query which throws the whole thing off. It is equivalent to saying
"select sum(credit_hrs) as fallfte from courses_instances where year= 'and' semester='Fall' and person_id=1074"

See what I mean? If you need the possibility of having a blank year then you need to surround that variable with single quotes so that the parser can evaluate it correctly.
