Given records from the Player table:
and given the code fragment:
try {
Connection conn = DriverManager.getConnection(URL, username, password); Statement st= conn.createStatement( ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE); st.execute ("SELECT * FROM Player"); st.setMaxRows(2); ResultSet rs = st.getResultSet(); rs.absolute(3); while (rs.next ()) { System.out.println(rs.getInt(1) + " " + rs.getString(2));
}
} catch (SQLException ex) {
System.out.print("SQLException is thrown.");
}
Assume that:
The required database driver is configured in the classpath.
The appropriate database is accessible with URL, username, and password.
The SQL query is valid.
