java实现简单的给sql语句赋值的示例

代码本身很简单。拼接sql的时候？不好数，简单的用来赋值。

复制代码 代码如下:

 public static void setParam(PreparedStatement pt, List list) throws SQLException{
  for(int i = 0;i   if (list.get(i) instanceof String) pt.setString(i+1, list.get(i).toString());
   else if(list.get(i) instanceof Integer) pt.setInt(i+1, Integer.parseInt(list.get(i).toString()));
   else if(list.get(i) instanceof Short)pt.setShort(i+1, Short.parseShort(list.get(i).toString()));
   else pt.setObject(i+1, list.get(i));
  }
 }
