的ResultSet不滾動

請看看下面的代碼的ResultSet不滾動

public List searchData(String query) 
    { 
     List data = new ArrayList(); 

     try 
     { 
      createConnection(); 

      Statement st = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE); 
      ResultSet rs = st.executeQuery(query); 


       while(rs.next()) 
       { 

       data.add(rs.getString(2)); 
       data.add(rs.getString(11)); 
       data.add(rs.getString(12)); 
       data.add(rs.getInt(3)); 
       data.add(rs.getInt(4)); 
       data.add(rs.getInt(5)); 
       data.add(rs.getInt(6)); 
       data.add(rs.getString(7)); 
       data.add(rs.getString(8)); 
       data.add(rs.getString(9)); 
       data.add(rs.getString(10)); 

       } 


       for(int i=0;i<data.size();i++) 
       { 
        System.out.println(data.get(i)); 
       } 

       System.out.println("Size of the array: "+data.size()); 



     } 
     catch(Exception e) 
     { 
      e.printStackTrace(); 
     } 
     finally 
     { 
      closeConnection(); 
     } 
}

此代碼是給下面的錯誤

這是爲什麼？如果我在末尾放置

data.add(rs.getString(11)); 
data.add(rs.getString(12));

，則此錯誤不會發生。我甚至將結果集設置爲可滾動！爲什麼是這樣？請幫忙！

請勿使用數字作爲索引。從結果集中檢索數據時始終使用列名稱。這樣可以更輕鬆地在表格上進行修改而不會影響現有的代碼。 – giorashc

這不是問題。我現在做了。沒有好的 –

「滾動」結果集與在不同行之間前後移動有關。您在獲得行的列值時遇到問題。一些jdbc驅動程序對列順序很敏感，我不認爲這是一個設置的事情。我想說你要麼需要按順序讀取列，要麼可能尋找一個不同的jdbc驅動程序。

真棒..是的，我正在做所有那些「while（rs.next（））」，它檢查相同的原料，並繼續前進。我決定把所有這些數據分解成單獨的變量，然後做任何我需要的。非常感謝回覆:) –
