SQL Server 2005中写文件的方法

--创建写文件的存储过程
ALTER proc [dbo].[p_movefile]
 @filename varchar(1000),--要操作的文本文件名  
 @text varchar(8000),   --要写入的内容
 @obj int
as  
begin
 declare @err  int,
   @src  varchar(255),
   @desc varchar(255)   
   
 exec @err=sp_oamethod @obj, 'OpenTextFile', @obj  out, @filename,8,1  
 if @err<>0  
  goto lberr  
 exec @err=sp_oamethod   @obj,'WriteLine',null,@text  
 if @err<>0  
  goto lberr  
   
 exec @err=sp_oadestroy @obj  
 return    
lberr:  
 exec sp_oageterrorinfo 0, @src out,@desc out  
 select cast(@err as  varbinary(4)) as 错误号,@src as 错误源,@desc as 错误描述
end
--调用上面的p_movefile的存储过程，将数据库查询内容写入到文件中去ALTER proc [dbo].[abc]
