SQL Date guru in the house?

Hi All, I have a small problem. I have a project in which someone has got three integer fields for holding the date. DD, MM, YYYY in an sql database. I now have to have a page that inputs two dates and select records between those two dates. If I had a date field in the table it would be fairly simple, but I'm hoping to do this search/comparison without having to rewrite the pages/database that has already been designed. Start Date: 11/05/2005 End Date: 11/04/2005 SELECT * FROM blah WHERE mm BETWEEN 04 AND 05 AND dd BETWEEN 11 AND 11 AND yyyy BETWEEN 2005 AND 2005 Doesn't work for obvious reasons. Is there any way that I can do this date comparison I the SQL statement without having a decent date field? My apologies as this is australian date format and this list is in the US I think?
