Self Deleting Job

,

I am a Production DBA, and my team supports several thousands instances of MS SQL.

Frequently, we get a request to grant temporary access to server XYZ, either sysadmin or DBO to certain databases.

It has become a challenge to remember to go back and remove the privileges, so I devised a little script to take care of it.

It's nothing really new, it is just a job with a self deleting feature, where I add a step to delete the job.

What do you need to do?

Give the Job a name, a schedule, and the TSQL command that you want to run. That simple!

After the job runs, it will self-destruct.

Error Handling:

Since the Job is deleting it self before it finish executing, there will be an entry on your SQL Agent log that would say:

[180] Job SelfDeletingJob was deleted while it was executing: the outcome was (Unknown)
