// Since JDBC 2.0 (JDK 1.2) a scrollable ResultSet was
// introduced to the java.sql API family. Using this
// ResultSet enables us to navigate the resultset in
// forward or backward way.
//
// To enable the scrollable ResultSet we need to create
// a statement object by defining the ResultSet type
// (ResultSet.TYPE_SCROLL_SENSITIVE,
// ResultSet.TYPE_SCROLL_INSENSITIVE). If you define the
// ResultSet type to ResultSet.TYPE_FORWARD_ONLY then you
// get a regular ResultSet where you can move forward
// only as in JDBC 1.0
//
Statement statement = connection.createStatement(
ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
//
// This result set is a scrollable result set
//
