問題的SQL和問號

我試圖用PreparedStatemnent執行腳本：問題的SQL和問號

import java.sql.*; 

public class DeclaredStatement { 

    public static void main(String[] args) throws SQLException { 

    try {  
     Class.forName("com.mysql.jdbc.Driver"); 
     Connection conn = 
     DriverManager.getConnection("jdbc:mysql://localhost/test"); 
     PreparedStatement stmt = conn.prepareStatement("" 
     + "SELECT TITLE FROM MOVIES" 
     + "WHERE year_made >= ? " 
     + "and year_made < ?"); 

     for (int decadeStart=1920;decadeStart<2000;decadeStart+=10) { 
     System.out.println("==== Movies of the " + decadeStart + "s ===="); 
     stmt.setInt(1, decadeStart); 
     stmt.setInt(2, decadeStart+10); 
     ResultSet rs = stmt.executeQuery(); 
     while (rs.next()) { 
      System.out.println(rs.getString(1)+" - "+rs.getInt(2)); 
     } 
     } 

    } catch (SQLException e) { 
     e.printStackTrace(); 
    } catch (ClassNotFoundException ex) { 
     ex.printStackTrace(); 
    } 

    } 

}

的錯誤是：

run: 
==== Movies of the 1920s ====

年份列的類型是什麼？ – pap 2011-06-13 06:52:54

此外，System.out.println（rs.getString（1）+「 - 」+ rs.getInt（2））應該失敗，因爲您只從表中選擇一列。 – pap 2011-06-13 06:53:27
