You can't directly check the database. The only way that you can check a database is by submitting the form. Since onBlur runs on the client-side, you can't really check the DB.

If you want to code a brute force hack, you can store the database in a javascript array, then parse the array each time.

IF you decide to use Java, you can create an applet that will check the database dynamically, but that is way beyond the scope of this message board.

hope this helps.
