/**********************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
