        print param
        print len(param)
        cursor.prepare('insert into game_server_name(server_id, server_name, chinese_name) values(:1, :2, :3)') # 一次插入全部数据
        cursor.executemany(None, param)
        db.commit()
    except Exception, err:
        print err
    finally:
        cursor.close()
        db.close()
        file_object.close()

def main():
    read_json_file('E:/android.json')
    read_json_file('E:/apple.json')

if __name__ == '__main__':
    main()

当只有一次参数的时候，也要把它写成元组的形式：

例如：Cursor.execute(‘select name from user where id=:1’,(login_Id,))

千万要注意： login_id 后面还带有一个逗号
