Hi , I'm using mysql driver for JDBC ("org.gjt.mm.mysql.Driver"). I am using result set and i want to update a record that exists in the set. In order to do so i used the following code: rs.updateString(4,"8888"); rs.updateRow(); and i got "java.lang.AbstractMethodError" when updateRow() was called. Does anybody know why this driver doesn't implement this method ? How can i update my database instead ? TIA , Yuval Katz
