PreparedStatement 查詢時無效的列索引 .

PreparedStatement 查詢時無效的列索引
在使用PreparedStatement  僅對oracle數據庫進行查詢是在   ps.setObject(i, values[i]);老是提示無效的列索引

錯誤代碼代碼
public List queryForBeans(final String sql, final Object... values)  {  
        Connection connection = null;  
        try {  
            connection = super.getDataSource().getConnection();  
            PreparedStatement ps = connection.prepareStatement(sql, ResultSet.TYPE_SCROLL_SENSITIVE,

ResultSet.CONCUR_READ_ONLY);  
            if (values != null) {  
                for (int i = 0; i < values.length; i++) {  
                    ps.setObject(i, values[i]);  
                }  
            }  
            ResultSet rs = ps.executeQuery();  
            RowSetDynaClass rsdc = new RowSetDynaClass(rs);  
            rs.close();  
            ps.close();  
            return rsdc.getRows();  
 
        } catch (SQLException ex) {  
            throw this.getExceptionTranslator().translate("", sql, ex);  
        } finally {  
            this.close(connection);  
        }  
    } 

public List queryForBeans(final String sql, final Object... values)  {
  Connection connection = null;
  try {
   connection = super.getDataSource().getConnection();
   PreparedStatement ps = connection.prepareStatement(sql, ResultSet.TYPE_SCROLL_SENSITIVE,

ResultSet.CONCUR_READ_ONLY);
   if (values != null) {
    for (int i = 0; i < values.length; i++) {
     ps.setObject(i, values[i]);
    }
   }
   ResultSet rs = ps.executeQuery();
   RowSetDynaClass rsdc = new RowSetDynaClass(rs);
   rs.close();
   ps.close();
   return rsdc.getRows();

  } catch (SQLException ex) {
   throw this.getExceptionTranslator().translate("", sql, ex);
  } finally {
   this.close(connection);
  }
 } 
後來在網上收了下原來是ps的參數是從1開始的而不是從0開始的，全部老是報無效的列索引，改成    ps.setObject(i+1, values

[i]);這樣就ok了。還有在網上也看到有人出現一樣的問題，但不是我這樣的問題，而是下標的數量與?的數量不一致，或者將?寫成

了？
