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

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
