【问题描述】：
我需要知道给定的作业当前是否正在 Ms SQL 2008 服务器上运行。以免再次调用可能导致并发问题的相同作业。

SSMS 的 SQL Server 代理部分中的作业活动监视器。

【问题描述】：
看来您可以使用msdb.dbo.sysjobactivity，检查具有非空 start_execution_date 和空 stop_execution_date 的记录，这意味着作业已开始，但尚未完成。
这将为您提供当前正在运行的作业：
SELECT sj.name
, sja.*
FROM msdb.dbo.sysjobactivity AS sja
INNER JOIN msdb.dbo.sysjobs AS sj ON sja.job_id = sj.job_id
WHERE sja.start_execution_date IS NOT NULL
AND sja.stop_execution_date IS NULL
【讨论】：
-
这报告了我的服务器上的一些未运行的作业。
-
我对 sysjobactivity 了解不够。我只知道我有一份工作符合您过去几次活动的活动地点标准。即不是当前的或最新的。该作业当前处于空闲状态。我不知道这是否代表取消，或计划外重启等（SQL2008R2）
-
我只是觉得，当我看到这个答案有问题时，我应该说点什么，让未来的人不要绝对当面接受。我现在已经不得不从这个主题继续前进了。
-
这包括已开始但因出错而未完成的作业。
EXEC msdb.dbo.sp_help_job效果更好 -
我在这里得到了更好的答案 dba.stackexchange.com/questions/58859/…，请参阅 Kenneth Fisher 的回答，它只返回当前正在运行的作业
我找到了better answer by Kenneth Fisher。以下查询仅返回当前正在运行的作业：
SELECT
ja.job_id,
j.name AS job_name,
ja.start_execution_date,
ISNULL(last_executed_step_id,0)+1 AS current_executed_step_id,
Js.step_name
FROM msdb.dbo.sysjobactivity ja
LEFT JOIN msdb.dbo.sysjobhistory jh ON ja.job_history_id = jh.instance_id
JOIN msdb.dbo.sysjobs j ON ja.job_id = j.job_id
JOIN msdb.dbo.sysjobsteps js
ON ja.job_id = js.job_id
AND ISNULL(ja.last_executed_step_id,0)+1 = js.step_id
WHERE
ja.session_id = (
SELECT TOP 1 session_id FROM msdb.dbo.syssessions ORDER BY agent_start_date DESC
)
AND start_execution_date is not null
AND stop_execution_date is null;
您可以通过在 select 子句中从 msdb.dbo.sysjobactivity 表中添加更多列来获取有关作业的更多信息。
【讨论】：
-
这个脚本的一个重要特性是它只选择在当前 SQL 代理会话中运行的作业。前一个 SQL 代理会话结束时正在运行的作业也将具有 NULL stop_execution_date。我们想排除那些，因此
ja.session_id = (SELECT TOP 1 session_id FROM msdb.dbo.syssessions ORDER BY agent_start_date DESC) -
应该将此答案保留为原始答案的链接，而不是复制代码，因为有一条有用的注释突出了限制：'不幸的是，此脚本假定当前正在运行的步骤是最后完成的步骤。情况并非总是如此'
-
如何找到作业运行时可能出现的错误？
EXEC msdb.dbo.sp_help_job @Job_name = 'Your Job Name'
检查字段execution_status
0 - 仅返回那些未空闲或挂起的作业。
1 - 正在执行。
2 - 等待线程。
3 - 重试之间。
4 - 空闲。
5 - 暂停。
7 - 执行完成动作。
如果需要执行结果，勾选last_run_outcome
0 = 失败
1 = 成功
3 = 取消
5 = 未知
【讨论】：
给定一份工作（我假设你知道它的名字），你可以使用：
EXEC msdb.dbo.sp_help_job @Job_name = 'Your Job Name'
如MSDN Job Help Procedure 中所建议的那样。 它返回很多关于作业的信息（所有者、服务器、状态等）。
【讨论】：
此查询将为您提供当前正在运行的作业的准确输出。这还将以分钟为单位显示正在运行的作业的持续时间。

EXECUTE master.dbo.xp_sqlagent_enum_jobs 1,''
注意Running列，显然1表示当前正在运行，[Current Step]。 这会将 job_id 返回给您，因此您需要查找这些内容，例如：
SELECT top 100 *
FROM msdb..sysjobs
WHERE job_id IN (0x9DAD1B38EB345D449EAFA5C5BFDC0E45, 0xC00A0A67D109B14897DD3DFD25A50B80, 0xC92C66C66E391345AE7E731BFA68C668)

我们已经找到并一直在使用此代码作为一个很好的解决方案。此代码将启动一个作业，并对其进行监控，如果超过时间限制，将自动终止该作业。

谢谢！通过一些小的调整，这对我们来说非常有效。
您可以查询表 msdb.dbo.sysjobactivity 以确定作业当前是否正在运行。
