而（rs.next（））没有执行

Question

抱歉代码很大。问题是rs.next似乎根本不执行，因为 System.out.println("//////////////////////////////////");不会打印任何内容。

String Temp2;
    Temp2 = ""; //initialise variable
    System.out.println("*************************************************");
    try
    {
        String filename = "Database.mdb";
        String database = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=";
        database += filename.trim() + ";DriverID=22;READONLY=false";
        conn = DriverManager.getConnection(database, "", "");

        for(int id = 1; id < 16; id++)//will repeat 15 times (for each player)
        {
            for(int x = 1; x < 18; x++)//will repeat 18 times (once for each team fixture)
            {
            Statement sta2 = conn.createStatement();

            ResultSet rs2 = sta2.executeQuery("SELECT * FROM tblPlayers WHERE PlayerID = "+ PlayerID +" AND FixtureNumber = "+ x);

                while (rs2.next())
                {
                    Temp2 = rs2.getString("PlayerName");
                    System.out.println("//////////////////////////////////");
                    System.out.println(Temp2 + ":Temp2");
                    Total = Total + rs2.getInt("Goals");//calculating total
                    System.out.println(Total + ":Total");
                }
            }
                        if (Total.equals(TotalsRev[0])){
                            PlayerName[0] = Temp2;
                        }else if (Total.equals(TotalsRev[1])){
                            PlayerName[1] = Temp2;
                        }else if (Total.equals(TotalsRev[2])){
                            PlayerName[2] = Temp2;
                        }else if (Total.equals(TotalsRev[3])){
                            PlayerName[3] = Temp2;
                        }else if (Total.equals(TotalsRev[4])){
                            PlayerName[4] = Temp2;
                        }
        }
        PlayerID = 0;//reset variable
        for(int x = 0; x < 5; x++){
            System.out.println(PlayerName[x]);                
        }
        System.out.println("*********************************************");
        System.out.println(TotalsRev[0]);
        System.out.println(TotalsRev[1]); 
        System.out.println(TotalsRev[2]); 
        System.out.println(TotalsRev[3]); 
        System.out.println(TotalsRev[4]); 

        jLabel10.setText(PlayerName[0] + "");
        jLabel11.setText(PlayerName[1] + "");
        jLabel12.setText(PlayerName[2] + "");
        jLabel13.setText(PlayerName[3] + ""); 
        jLabel14.setText(PlayerName[4] + "");
    }
    catch (Exception e)
    {
    System.out.println("Exception displayTotalAttributes:" + e);
    }
    finally //close down connection to prevent "too many tables open" error
    {
        if (conn != null) {
            try {
            conn.close();
            } catch (SQLException e) {}
        }
    }

控制台中的输出是：
“的 ********************************************* < /强>“
// System.out.println("//////////////////////////////////");应该在这里执行 Omicron //团队名称
null //这些也应该是团队名称 null
null
null
“的 ***************************************** ”
