Hello guys,
Good afternoon.
After a while without posting, today I will demonstrate in this post how to identify jobs running via Query in SQL Server. With this query, you can identify the name and id of the job, which step the job is running, which query it has been running now and how long ago.
How to identify jobs running via Query
During the day to day, we can always monitor the queries that are running in our environment, especially using the great procedure sp_whoisactive. However, even with this excellent tool, it is not so trivial to find out via Query, if a job has been running, how long, which step, etc.
To this end, I will demonstrate a query (I created as a view for easy query) that helps us with this task:

If you are using a version of SQL Server earlier than version 2012, this query above will return an error message on account of TRY_CONVERT. To do this, I have another query, which uses the BINARY_CHECKSUM function to validate if the string is in BINARY format:

Or it has a slightly simpler query, which does not return the job session_id, hostname, user, program, nor the query being executed, but returns all information related to the Jobs that are running on the instance:

Another way to identify running jobs is by using the undocumented system procedure, xp_sqlagent_enum_jobs. This procedure is intended to list all instance jobs, stating the last run date and time, next run date and time, binary flag if the job is currently running (running), the number of the running step ( Current_Step), the number of Retry retries and the current state of execution.

EXEC master.dbo.xp_sqlagent_enum_jobs 1, '' |
Working a little with this sp, we can get a more effective result for our need:

That's it folks!
See you!
