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