如果要导出数据到已经生成结构(即现存的)FOXPRO表中,可以直接用下面的SQL语句

insert into openrowset('MSDASQL',
'Driver=Microsoft Visual FoxPro Driver;SourceType=DBF;SourceDB=c:\',
'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。
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
用bcp实现的存储过程

/*
实现数据导入/导出的存储过程
根据不同的参数,可以实现导入/导出整个数据库/单个表
调用示例:
--导出调用示例
----导出单个表
exec file2table 'zj','','','xzkh_sa..地区资料','c:\zj.txt',1
----导出整个数据库
exec file2table 'zj','','','xzkh_sa','C:\docman',1
--导入调用示例
----导入单个表
exec file2table 'zj','','','xzkh_sa..地区资料','c:\zj.txt',0
----导入整个数据库
exec file2table 'zj','','','xzkh_sa','C:\docman',0
*/
if exists(select 1 from sysobjects where name='File2Table' and objectproperty(id,'IsProcedure')=1)
drop procedure File2Table
go
create procedure File2Table
@servername varchar(200) --服务器名
,@username varchar(200) --用户名,如果用NT验证方式,则为空''
,@password varchar(200) --密码
,@tbname varchar(500) --数据库.dbo.表名,如果不指定:.dbo.表名,则导出数据库的所有用户表
,@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
+case when @isout=1 then ' out ' else ' in ' end
+' "'+@filename+'" /w'
+' /S '+@servername
+case when isnull(@username,'')='' then '' else ' /U '+@username end
+' /P '+isnull(@password,'')
exec master..xp_cmdshell @sql
end
else
begin --导出整个数据库,定义游标,取出所有的用户表
declare @m_tbname varchar(250)
if right(@filename,1)<>'\' set @filename=@filename+'\'
set @m_tbname='declare #tb cursor for select name from '+@tbname+'..sysobjects where xtype=''U'''
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
