在我管理的系统中，有几个 SQL Server 代理作业根据 dbo.sysschedules 中定义的计划运行。
我想在我的应用程序上创建一个日历视图，该视图将显示这些作业中的每一个何时计划在给定的时间跨度内运行。例如，如果我的计划设置为在每月的第一个和第四个星期一上午 8:00 运行，那么考虑到当月的时间跨度 (4/2013) 我想获得日期“4/1 /2013 上午 8:00，2013 年 4 月 22 日上午 8:00”返回。
有没有人遇到过实现这一目标的方法？我知道我可以阅读时间表定义并务实地解决这个问题，但我很好奇在我自己进入杂草之前是否有人已经提出了解决方案。
谢谢！
这些链接看起来会让你走上正确的道路......
这是我从 mssqltips.com 更改的解决方案。

这个查询的结果对我来说。

LastRunDateTime====4/23/13 19:47
NextRunDateTime====4/24/13 2:00
发生=========每天
重复=========每 1 天发生一次
我会看看这个工具并运行 Profiler 来查看它执行的查询。它是一个方便的工具。
在 MSDB 数据库中查看以下内容：
select sj.name, sch.next_run_date, sch.next_run_time
from sysjobschedules sch
inner join sysjobs sj
on sj.job_id = sch.job_id
