如何在没有作业运行时自动停止 SQL Server 代理？

我在一个实例中有大约 40 个不同的 SQL Server 作业。他们都有不同的时间表。有些每天运行一次，有些每两分钟运行一次，有些每五分钟运行一次。如果我需要停止 sql server 代理，如何找到没有作业运行的最佳时间，这样我就不会中断任何作业？

当没有作业运行时，如何找到最佳时间，这样我就不会中断任何作业？

您基本上想要找到一个好的窗口来执行一些维护。@马克斯弗农已经在博客上介绍过它here有一个方便的脚本

-- http://www.sqlserver.science/tools/gaps-between-sql-server-agent-jobs/
-- requires SQL Server 2012+ since it uses the LAG aggregate.
 Note: On SQL Server 2005, SQL Server 2008, and SQL Server 2008 R2, you could replace the LastEndDateTime column definition with:

       LastEndDateTime = (SELECT TOP(1) s1a.EndDateTime FROM s1 s1a WHERE s1a.rn = s1.rn - 1)
