Re: JDBC Question.Plese answer it....
I am not knowledgeable in this area. But referring the below link might help you to get answer for 1st question...
Get a load of that name! - Java World 2. execute() use this to run any DDL statements or SQL statements that don't return any thing. Returns boolean. executeQuery() - use this to capture and process output of a query. Returns ResultSet executeUpdate() - use this to execute update SQL statements. Returns the number of rows updated with the current update statement execution. Returns integer. Thanks, Krishna

Re: JDBC Question.Plese answer it....
There are three ways of loading jdbc driver
one is: Class.forName() 2 is: DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver()); Connection con = DriverManager.getConnection ("jdbc:oracle:thin:@127.0.0.1:1521:oracleinstancename","uname","pwd"); 3 is: At Runtime java -Djdbc.drivers=drivername Programname Thanks.
