Arguments

[ @job_id = ] 'job_id'

The job identification number of the job to remove the schedule from. @job_id is uniqueidentifier, with a default of NULL.

Either @job_id or @job_name must be specified, but both can't be specified.

[ @job_name = ] N'job_name'

The name of the job to remove the schedule from. @job_name is sysname, with a default of NULL.

Either @job_id or @job_name must be specified, but both can't be specified.

[ @schedule_id = ] schedule_id

The schedule identification number of the schedule to remove from the job. @schedule_id is int, with a default of NULL.

Either @schedule_id or @schedule_name must be specified, but both can't be specified.

[ @schedule_name = ] N'schedule_name'

The name of the schedule to remove from the job. @schedule_name is sysname, with a default of NULL.

[ @delete_unused_schedule = ] delete_unused_schedule

Specifies whether to delete unused job schedules. @delete_unused_schedule is bit, with a default of 0, which means that all schedules are kept, even if no jobs reference them. If set to 1, unused job schedules are deleted if no jobs reference them.

Permissions

This stored procedure is owned by the db_owner role. You can grant EXECUTE permissions for any user, but these permissions may be overridden during a SQL Server upgrade.

Other users must be granted one of the following SQL Server Agent fixed database roles in the msdb database:

  • SQLAgentUserRole
  • SQLAgentReaderRole
  • SQLAgentOperatorRole

The job owner can attach a job to a schedule and detach a job from a schedule without also having to be the schedule owner. However, a schedule can't be deleted if the detach would leave it with no jobs unless the caller is the schedule owner.

For details about the permissions of these roles, see SQL Server Agent Fixed Database Roles.

SQL Server checks to determine whether the user owns the schedule. Only members of the sysadmin fixed server role can detach schedules from jobs owned by another user.

Examples

The following example removes an association between a NightlyJobs schedule and a BackupDatabase job.

USE msdb;
GO

EXEC dbo.sp_detach_schedule
    @job_name = 'BackupDatabase',
    @schedule_name = 'NightlyJobs';
GO
