SQL语句导入导出大全

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

@servername varchar(200) --服务器名
,@username varchar(200) --用户名,如果用NT验证方式,则为空''''
,@password varchar(200) --密码
,@tbname varchar(500) --数据库.dbo.表名,如果不指定:.dbo.表名,则导出数据库的所有用户表
,@filename varchar(1000) --导入/导出路径/文件名,如果@tbname参数指明是导出整个数据库,则这个参数是文件存放路径,文件名自动用表名.txt
,@isout bit --1为导出,0为导入

EXEC sp_addlinkedserver ''OracleSvr'',

''ORCLDB''
GO

delete from openquery(mailser,''select * from yulin'')

select * from openquery(mailser,''select * from yulin'')

update openquery(mailser,''select * from yulin where id=15'')set disorder=555,catago=888

insert into openquery(mailser,''select disorder,catago from yulin'')values(333,777)

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
