I look somethings like;

declare @rc = int,

@JobID uniqueidentifier

select @JobID = forjob

exec @rc = xxx.dbo.sp_add_jobschedule

@job_id = @forjob, -- ID of job you create the schedule for

@name = N'10 sec recurring', -- name of the schedule

@enabled = 1, -- enable the schedule for use

@freq_type = 4, -- daily frequency

@active_start_date = 20080508, -- date from which schedule will be active (July 6, 2003)

@active_start_time = 16, -- time from which schedule will be active (midnight)

@freq_interval = 1, -- unused for daily

@freq_subday_type = 2, -- seconds

@freq_subday_interval = 10, -- every 10 seconds

@freq_relative_interval = 0, -- unused for daily

@freq_recurrence_factor = 0, -- unused for daily

@active_end_date = 99991231, -- date which schedule becomes inactive (Dec. 31, 9999)

@active_end_time = 20080509 -- time which schedule becomes inactive (23:59:59)

if (@@error <> 0 or @rc <> 0) raiserror('Error creating job schedule', 1, 16)

USE msdb ;

EXEC sp_add_jobstep

@job_name = N'forjob',

@step_name = N'Set database to read only',

@subsystem = N'TSQL',

@command = N'exec forjob',

@retry_attempts = 5,

@retry_interval = 5 ;
