Welcome to the Ranch 'Zombie UOR'! You'll find this forum a great place to seek help on JDBC, and there aren't many rules you'll have to worry about, but one is that proper names are required. Please take a look at the JavaRanch Naming Policy and change your display name to match it. In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious. Thanks! bear JDBC/JSP Forum Bartender
