  'select * from [aa.dbf]')
  select * from 表

  说明:
  sourcedb=c:\ 指定foxpro表所在的文件夹
  aa.dbf 指定foxpro表的文件名.

  /**********************excel导到txt****************************************/
  想用
  select * into opendatasource(...) from opendatasource(...)
  实现将一个excel文件内容导入到一个文本文件

  假设excel中有两列,第一列为姓名,第二列为很行帐号(16位)且银行帐号导出到文本文件后分两部分,前8位和后8位分开。


  邹健:
  如果要用你上面的语句插入的话,文本文件必须存在,而且有一行:姓名,银行账号1,银行账号2然后就可以用下面的语句进行插入
注意文件名和目录根据你的实际情况进行修改.

  insert into
  opendatasource('microsoft.jet.oledb.4.0'
  ,'text;hdr=yes;database=c:\'
  )...[aa#txt]
  --,aa#txt)
  --*/
  select 姓名,银行账号1=left(银行账号,8),银行账号2=right(银行账号,8) 
  from 
  opendatasource('microsoft.jet.oledb.4.0'
  ,'excel 5.0;hdr=yes;imex=2;database=c:\a.xls'
  --,sheet1$)
  )...[sheet1$]


  如果你想直接插入并生成文本文件,就要用bcp declare @sql varchar(8000),@tbname varchar(50)

  --首先将excel表内容导入到一个全局临时表
  select @tbname='[##temp'+cast(newid() as varchar(40))+']',@sql='select 姓名,银行账号1=left(银行账号,8),银行账号2=right(银行账号,8) 
  into '+@tbname+' from 
  opendatasource(''microsoft.jet.oledb.4.0''
  ,''excel 5.0;hdr=yes;imex=2;database=c:\a.xls''
  )...[sheet1$]'
  exec(@sql)

  --然后用bcp从全局临时表导出到文本文件
  set @sql='bcp "'+@tbname+'" out "c:\aa.txt" /s"(local)" /p"" /c'
  exec master..xp_cmdshell @sql

  --删除临时表
  exec('drop table '+@tbname)
  /********************导整个数据库*********************************************/

  if exists(select 1 from sysobjects where name='file2table' and objectproperty(id,'isprocedure')=1)

  ,@filename varchar(1000) --导入/导出路径/文件名,如果@tbname参数指明是导出整个数据库,则这个参数是文件存放路径,文件名自动用表名.txt
  ,@isout bit --1为导出,0为导入
  as
  declare @sql varchar(8000)

  if @tbname like '%.%.%' --如果指定了表名,则直接导出单个表
  begin
  set @sql='bcp '+@tbname

  else

  exec(@m_tbname)
  open #tb
  fetch next from #tb into @m_tbname
  while @@fetch_status=0
  begin
  set @sql='bcp '+@tbname+'..'+@m_tbname
  +case when @isout=1 then ' out ' else ' in ' end
  +' "'+@filename+@m_tbname+'.txt " /w'
  +' /s '+@servername
  +case when isnull(@username,'')='' then '' else ' /u '+@username end
  +' /p '+isnull(@password,'')
  exec master..xp_cmdshell @sql
  fetch next from #tb into @m_tbname
  end
  close #tb
  deallocate #tb 
  end
  go

  /************* oracle **************/
  exec sp_addlinkedserver 'oraclesvr', 
  'oracle 7.3', 
  'msdaora', 
  'orcldb'
  go

  delete from openquery(mailser,'select * from yulin')

  select * from openquery(mailser,'select * from yulin')

  update openquery(mailser,'select * from yulin where id=15')set disorder=555,catago=888

  insert into openquery(mailser,'select disorder,catago from yulin')values(333,777)

  补充:

  对于用bcp导出,是没有字段名的.

  用openrowset导出,需要事先建好表.

  用openrowset导入,除access及excel外,均不支持非本机数据导入
