/***************** 导出到DBF ***************/
如果要导出数据到已经生成结构(即现存的)FOXPRO表中,可以直接用下面的SQL语句

insert into openrowset('MSDASQL',
'Driver=Microsoft Visual FoxPro Driver;SourceType=DBF;SourceDB=c:\',
'select * from [aa.DBF]')
select * from 表

说明:
SourceDB=c:\ 指定foxpro表所在的文件夹
aa.DBF 指定foxpro表的文件名.

/*************导入Access********************/
insert into B表 selet * from openrowset('Microsoft.Jet.OLEDB.4.0',

用bcp实现的存储过程


/*
实现数据导入/导出的存储过程
根据不同的参数,可以实现导入/导出整个数据库/单个表
调用示例:
--导出调用示例
----导出单个表
exec file2table 'zj','','','xzkh_sa..地区资料','c:\zj.txt',1
----导出整个数据库
exec file2table 'zj','','','xzkh_sa','C:\docman',1

--导入调用示例
----导入单个表
exec file2table 'zj','','','xzkh_sa..地区资料','c:\zj.txt',0
----导入整个数据库
exec file2table 'zj','','','xzkh_sa','C:\docman',0
