Generate the Jobs script from msdb Database

前两周，由于数据库简繁体的转换，大量的数据库需要转到新的服务器。 在转其中的一台的时候，原先导出来的JOBS脚本不翼而飞（原因至今未明），而恰巧这一台服务器有90多个JOB（看下图恢复后的，注意滚动条的长短），这样一来，可急坏了人了。 这么多的JOB要一个一个建立，时间去了不说，有些JOB根本不知道执行的是哪些命令，执行顺序如何，这么多的系统相互交纵复杂，如果不能正确的处理好，星期一可就乱了套了。到时谁都不会有好果子吃。 由于JOBS都是存在于msdb数据库，还好，我们平时是有备份这个数据库的，这样一来，我们应该想办法从这个数据库里取回一些有用的信息。 首先，我应该恢复一个msdb数据库为别的名字，然后赶紧求助于互联网。经过了一番摸索终于可以从该数据库中提取出脚本。 现在把这脚本也放出来，希望有此需要的人做参考使用，亦或大家做学习之用，如果大家有好的方法也请讲出。 当然，要是在系统完好之前，直接备份就用不着这么麻烦了，直接在图形介面产生的脚本又快又准确。
