sql如何向⼀个表中批量插⼊⼤量数据--如果两表结构⼀样。
insert into tb1 select * from tb2
--也可以尝试从excel或access或TXT等⽂件导⼊。参考如下：

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

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
