【概要说明】

    <中文名称>    作业迁移
    <功能说明>    通过insert、update语句导入作业信息，目的是将实例A中的作业迁移到实例B中
    <调用方式>    手动执行
    <执行说明>    先决条件：还原前请先备份两边的msdb数据库，将实例A中的msdb还原到实例B的msdbnew
            　    出错处理：如果出错，请还原原备份文件
            　    注意事项：此代码适用用于数据库版本不一致，且迁移的作业比较多的情况；如果版本号相同，可直接还原数据库

--1重启代理服务;2禁用作业再启用作业;3修改并保存作业
--应该可以直接执行某个语句(暂时没找到)
