DFo*_*k42 5 sql-server-2005 sql-server
我正在尝试为报告创建一个视图，以便我可以轻松跟踪我在服务器上安排的所有备份。所有这些备份都安排在维护计划的子计划中，因此作业名称都以“Backup.”开头。
我遇到的问题是，我希望能够轻松查看作业计划再次运行的时间以及计划的频率。sysschedules 表具有字段 freq_type 和 freq_interval。可以在此处找到它们的值的定义。正如您所看到的，由于缺乏更好的描述方式，这些字段是累积的。我不知道如何在基于集合的解决方案中进行设置，以便我可以看到当天的名称。
我希望能够看到诸如“每 3 天执行一次”或“每周一、二、五执行”之类的内容。
我怎样才能写这个，这样我就不会使用多层 case 语句来得到我想要的东西？
到目前为止，这是我的代码：
select
j.job_id,
j.name,
s.next_run_date,
s.next_run_time,
ss.*
from msdb.dbo.sysjobs j
left outer join msdb.dbo.sysjobschedules s
on j.job_id=s.job_id
left outer join msdb.dbo.sysschedules ss
on s.schedule_id=ss.schedule_id
where j.name like 'backup.%'

如果您想要 SQL Server 使用的所有整数值的纯英文版本（至少就我对 T-SQL 的有限了解而言），除了使用 case 语句之外别无他法。这是很多 DBA 都需要的常见事情，并且有很多关于该主题的脚本。我发现下面来自 Michelle Ufford 的脚本对于很好地了解正在运行的作业时间表非常有用。由于维护计划最终会作为 SQL 代理作业，这也将向您展示这一点。
您从脚本中获得的输出将为您提供频率、子频率、预定时间以及下次运行时间和日期。我只是把她的脚本作为一个存储过程放在我的服务器上，这样我就可以在需要时轻松地运行它。如果你愿意，你也可以把它作为一个视图。由于其他人可以在我身后添加工作等，因此我喜欢时不时地检查一下，看看发生了什么。
