利用语句导出表到XLS中，为什么没有导出列名？

--可以考虑用下面的存储过程   

    

  if   exists   (select   *   from   dbo.sysobjects   where   id   =   object_id(N'[dbo].[p_exporttb]')   and   OBJECTPROPERTY(id,   N'IsProcedure')   =   1)   

  drop   procedure   [dbo].[p_exporttb]   

  GO   

    

  /*--数据导出Text   

    

  导出查询语句中的数据到Text,包含字段名   

  如果文件不存在,将自动创建文件   

  基于通用性考虑,仅支持导出标准数据类型
