如果要導出數據到已經生成結構(即現存的)FOXPRO表中,可以直接用下面的SQL語句
insert into openrowset(''''MSDASQL'''',

select * from 表
說明:
SourceDB=c:\ 指定foxpro表所在的文件夾
aa.DBF 指定foxpro表的文件名.

/**********************Excel導到Txt****************************************/
想用
select * into opendatasource(...) from opendatasource(...)
實現將一個Excel文件內容導入到一個文本文件
假設Excel中有兩列,第一列為姓名,第二列為很行帳號(16位)
且銀行帳號導出到文本文件後分兩部分,前8位和後8位分開。
鄒健:
如果要用你上面的語句插入的話,文本文件必須存在,而且有一行:姓名,銀行賬號1,銀行賬號2
然後就可以用下面的語句進行插入
注意文件名和目錄根據你的實際情況進行修改.
insert into
opendatasource(''''MICROSOFT.JET.OLEDB.4.0''''
,''''Text;HDR=Yes;DATABASE=C:\''''
)...[aa#txt]
--,aa#txt)
--*/
select 姓名,銀行賬號1=left(銀行賬號,8),銀行賬號2=right(銀行賬號,8)
from
opendatasource(''''MICROSOFT.JET.OLEDB.4.0''''
,''''Excel 5.0;HDR=YES;IMEX=2;DATABASE=c:\a.xls''''
--,Sheet1$)
)...[Sheet1$]
如果你想直接插入並生成文本文件,就要用bcp
declare @sql varchar(8000),@tbname varchar(50)
--首先將excel表內容導入到一個全局臨時表
select @tbname=''''[##temp''''+cast(newid() as varchar(40))+'''']''''
,@sql=''''select 姓名,銀行賬號1=left(銀行賬號,8),銀行賬號2=right(銀行賬號,8)
into ''''+@tbname+'''' from
opendatasource(''''''''MICROSOFT.JET.OLEDB.4.0''''''''
,''''''''Excel 5.0;HDR=YES;IMEX=2;DATABASE=c:\a.xls''''''''
)...[Sheet1$]''''
exec(@sql)
--然後用bcp從全局臨時表導出到文本文件
set @sql=''''bcp "''''+@tbname+''''" out "c:\aa.txt" /S"(local)" /P"" /c''''
exec master..xp_cmdshell @sql
--刪除臨時表
exec(''''drop table ''''+@tbname)

補充:
對於用bcp導出,是沒有字段名的.
用openrowset導出,需要事先建好表.
用openrowset導入,除ACCESS及EXCEL外,均不支持非本機數據導入
