Sometimes we have a T-SQL process that we need to run that takes some time to run or we want to run it during idle time on the server. We could create a SQL Agent job manually, but is there any simple way to create a scheduled job?
This tip contains T-SQL code to create a SQL Agent job dynamically instead of having to use the SSMS GUI.
I am going to create a stored procedure named sp_add_job_quick that takes a few parameters to create the job. For my example, I will create a SQL Agent job that will call stored procedure sp_who and the job will be scheduled to run once at 4:00 PM.
Creating a Stored Procedure to create SQL Agent jobs
In this sample we are going to create a job dynamically using T-SQL Code:
CREATE procedure [dbo].[sp_add_job_quick]
--Add a job
@job_name = @job ;
--Add a job step named process step. This step runs the stored procedure
@job_name = @job,
@step_name = N'process step',
@subsystem = N'TSQL',
@command = @mycommand
--Schedule the job at a specified date and time
exec sp_add_jobschedule @job_name = @job,
@name = 'MySchedule',
@active_start_date = @startdate,
@active_start_time = @starttime
-- Add the job to the SQL Server Server
@job_name = @job,
@server_name = @servername
This is a stored procedure named sp_add_job_quick that calls 4 msdb stored procedures:
sp_add_job creates a new job
sp_add_jobstep adds a new step in the job
sp_add_jobschedule schedules a job for a specific date and time
sp_add_jobserver adds the job to a specific server
Let's invoke the stored procedure in order to create the job:
@job = 'myjob', -- The job name
@mycommand = 'sp_who', -- The T-SQL command to run in the step
@servername = 'serverName', -- SQL Server name. If running localy, you can use @servername=@@Servername
@startdate = '20130829', -- The date August 29th, 2013
@starttime = '160000' -- The time, 16:00:00
If everything is OK, a job named myjob will be created with a step that runs the sp_who stored procedure that will run on August 29th at 4:00PM.
Explanation of the SQL Agent job creation code
Here I will walk through the code and what each step does.
The sp_add_job is a procedure in the msdb database that creates a job.
@job_name = @job
The sp_add_jobstep creates a job step in the job created. In this tip, the step name is process_step and the action is a TSQL command.
In the declare section we are assigning to the @mycommand variable the stored procedure sp_who.
The following section let's you create the schedule for the job in T-SQL. The schedule name is MySchedule. The frequency type is once (1). If you need to run the job daily the frequency type is 4 and weekly 8 . The active start time is 16:00:00 (4PM). The start date uses the date assigned to the startdate variable '20130823'.
Additional tables to find information about SQL Agent jobs
Here are some system tables in the msdb database that you can use to get job information. If you need to retrieve job information you may need them.
dbo.sysjobactivity - shows the current information of the jobs
dbo.sysjobhistory - shows the execution result of the jobs.
dbo.sysjobs - shows the information of the jobs programmed.
dbo.sysjobsshedules - shows the job schedule information like the next run date and time of the jobs.
dbo.sysjobservers - shows the servers assigned to run jobs
dbo.sysjobsteps - shows the job steps
dbo.sysjobsteplogs - let you see the logs of the steps configured to display the output in a table
SQL Agent Job stored procedures
You also have these stored procedures in the msdb database to retrieve job information:
I am not going to explain each system stored procedure, but in the next steps you can find links with an explanation for each.
If you want to modify and create your own procedures based on the Microsoft system stored procedures you can review the code using sp_helptext. In this example, we are reviewing sp_help_job. For example, to see the T-SQL code for sp_help_job code use this command:
The code is displayed here:

i am trying to schedule a job in ql server 2005 for calling a stored procedure daily at a fixe time, at the time of adding the steps i am getting the message in window 'after creating the steps that after executing the steps go to next step will goes to quit with success. is this intended behavoiur' . while clicking on yes it gives exception
'execute permission deny for sp_help_operator,msdb '.and it does not create the steps in job. could you provide me the solution .
I was not aware of some of those system stored procedures, so this is very enlightening. Thank you.
Just a small nitpick, but is " The active start time is 16:00:00 (00:00:00)." a typo? Should it read (04:00:00) to translate the 24-hour clock to the more conventional 12-hour clock? Or am I just misunderstanding something?
