Start Sql server agent job after a trigger
-
Is it possible to start Sql server agent job after a trigger? what i want to do is after a certain table updates a certain column, then it runs a job that has various sql stored procedures. if not possible at all, is there something similar to this?

Starting an SQL Server job from T-SQL is a "Fire and Forget" asynchronous task... but I probably would wouldn't do it from a trigger. Why not just add it to whatever is causing the update? Also remember that if a job is already running, you can't run it again until it completes.
With that in mind, it may be better to have your trigger write to a "que" table and have the job run once in a while to check the "que" table. That way, you won't miss anything if you update the certain column again before the job stops.
There might be a way to do this with Service Broker but I've never used it before and I can't say I'm a fan.

ok thank you, will see what the service broker can do.

Jeff's queueing idea is the way I would do it.

We use sqlserver alerts ( raiserror 50000+ ) and have sqlagent respond to it and launch a given job.
Keep in mind it may take SQLAgent up to 20 seconds to respond.

K... just remember that's not my first choice. For me personally, it wouldn't be a choice. Like I said, I'm not a fan of it. I probably shouldn't have even mentioned it.

every day a table gets updated from a linked server we have in our sql server (a server from a telecommunication company that gives us details about sales, login time, call time etc etc ). this table tells me that when execution is 0 the update from the database from their part was successful "LastsuccessfullyEndDate". the thing is, their database can be updated randomly throughout (09h00 15h00 and even 18h00). at the moment we are executing the job manually (that runs st. procedures that runs also their data). i created a trigger that sents email to me when their database has been updated. but it would be honey on bread if we could start the job on the same trigger has the sented mail. will try your solutions. this is a linked server i think this has to be keep in mind.

I would add a check in the agent job - and then schedule the agent job to run every xx time. The check looks at the table - if the LastSuccessfullyEndDate is greater than current date/time minus xx time, then a new update has occurred - so run your process.
I would probably schedule the job to run every hour, and check for a successful time after: DATEADD(hour, -1, getdate()).

You can start the job easily from the trigger using:
EXEC msdb.dbo.sp_start_job @job_name = '<your_job_name_here>'
That will just start the job and immediately return to the trigger (that is, I'm confirming that this command does not wait for the job to complete).
Just make sure, of course, that the trigger has authority to start a job.

That is not advisable as this will always start the job, even when it is disabled !
My point is: When a sysadmin or "sqlagent job manager" disables a job for certain maintenance time(s), when sp_startjob is used, the job will always get launched ! This may interfere with ongoing job-disabled-downtime.

If you want to, you can always check to verify that the job is enabled before starting it. So that concern won't prevent you from using this method. You could even have the trigger set a flag somewhere if the job was disabled that would start the job later if you deemed that to be really necessary.
