e270. Getting the Cursor Position in a Scrollable Result Set

    try {
        // Create a scrollable result set
        Statement stmt = connection.createStatement(
            ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
        ResultSet resultSet = stmt.executeQuery("SELECT * FROM my_table");
    
        // Get cursor position
        int pos = resultSet.getRow();            // 0
        boolean b = resultSet.isBeforeFirst();   // true
    
        // Move cursor to the first row
        resultSet.next();
    
        // Get cursor position
        pos = resultSet.getRow();                // 1
        b = resultSet.isFirst();                 // true
    
        // Move cursor to the last row
        resultSet.last();
    
        // Get cursor position
        pos = resultSet.getRow();                // If table has 10 rows, value would be 10
        b = resultSet.isLast();                  // true
    
        // Move cursor past last row
        resultSet.afterLast();
    
        // Get cursor position
        pos = resultSet.getRow();                // If table has 10 rows, value would be 11
        b = resultSet.isAfterLast();             // true
    } catch (SQLException e) {
    }
