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
