// 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,
