I think

SELECT *
FROM GLJOUR
WHERE Company >= :Company
AND (Company > :Company
OR (Account >= :Account
AND (Account > :Account
OR (Division >= :Division
AND (Division > :Division
OR (Department >= :Department
AND (Department > :Department
OR (EffectiveDate >= :EffectiveDate
AND (EffectiveDate > :EffectiveDate
OR ControlNumber >= : ControlNumber)))))))))

will achieve the same thing with lesser code.

Regarding the programmers opposing changing to a database, I would actually suggest that you implement something like they want. However, I would also recommend you to tell them it is like trying to make a sports car behave like a train and ask them if you could be allowed to change one (smallish, but sluggish) program so that it utilized Firebird the way it was intended to (and then let them compare the two versions).
