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.

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 '[email protected]+' 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 "'[email protected]+'" out "c:/aa.txt" /s"(local)" /p"" /c'
exec master..xp_cmdshell @sql --删除临时表
exec('drop table '[email protected])
