Applies to: SQL Server

Deletes a schedule.

Transact-SQL syntax conventions

Syntax

sp_delete_schedule
    [ [ @schedule_id = ] schedule_id ]
    [ , [ @schedule_name = ] N'schedule_name' ]
    [ , [ @force_delete = ] force_delete ]
    [ , [ @automatic_post = ] automatic_post ]
[ ; ]

Arguments

[ @schedule_id = ] schedule_id

The schedule identification number of the schedule to delete. @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 delete. @schedule_name is sysname, with a default of NULL.

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

[ @force_delete = ] force_delete

Specifies whether the procedure should fail if the schedule is attached to a job. @force_delete is bit, with a default of 0.

  • When @force_delete is 0, the stored procedure fails if the schedule is attached to a job.
  • When @force_delete is 1, the schedule is deleted regardless of whether the schedule is attached to a job.

[ @automatic_post = ] automatic_post

Identified for informational purposes only. Not supported. Future compatibility is not guaranteed.

Return code values

0 (success) or 1 (failure).

Result set

None.

Remarks

By default, a schedule can't be deleted if the schedule is attached to a job. To delete a schedule that is attached to a job, specify a value of 1 for @force_delete. Deleting a schedule doesn't stop jobs that are currently running.

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.

Only members of the sysadmin role can delete a job schedule that is owned by another user.

Examples

A. Delete a schedule

The following example deletes the schedule NightlyJobs. If the schedule is attached to any job, the example doesn't delete the schedule.

USE msdb;
GO

EXEC dbo.sp_delete_schedule
    @schedule_name = N'NightlyJobs';
GO

B. Delete a schedule attached to a job

The following example deletes the schedule RunOnce, regardless of whether the schedule is attached to a job.

USE msdb;
GO

EXEC dbo.sp_delete_schedule
    @schedule_name = 'RunOnce',
    @force_delete = 1;
GO
