Inserts Records into Access/SQL table - Java Database Connectivity

Home	»	Java	»	Advance Java	»	Java Database Connectivity	»	Inserts Records

This example inserts records into the Access table 'SchoolClasses' on the harddisk, using classes of the java.sql package the rows inserted.

•  A JDBC-ODBC bridge driver is loaded
•  A Connection to the database is made, using getConnection method()
•  Using the Connection object, SQL's 'Insert into' statement is sent to the database
•  A message is printed on the command line indicating the command was successful
•  Minimal exception handling is done

To insert rows into the table 'StudentTable' the executeUpdate() method is used. To display the results retrieved from the table the rs.next() method is used.
