Dates comarison in query fails ------------------------------ Key: HHH-963 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-963 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.0.5 Environment: Hibernate 3.0x, HSQL Reporter: Pavel Kaplin Assignee: Steve Ebersole Priority: Critical Expression like "date1 = date2" are being calculated incorrectly. When compared dates are equal, expression "date1 = date2" is false, but "date1 > date2" is true. It's not seems right. Try to use the following code in your Eg application: Session session = factory.openSession(); Date date = new Date(); AuctionItem auctionItem = new AuctionItem(); auctionItem.setEnds(date); session.save(auctionItem); session.close(); session = factory.openSession(); Query query = session.createQuery("SELECT item FROM org.hibernate.auction.AuctionItem AS item WHERE item.ends = :date"); query.setDate("date", date); List list = query.list(); System.out.println("Date = " + date.getTime()); System.out.println("AuctionItem.date = " + ((AuctionItem) list.iterator().next()).getEnds().getTime()); System.out.println("List size == " + list.size()); if (list.size() != 1) throw new RuntimeException ("AAAAAAAAAAAAAA!");
