Permissions

By default, members of the sysadmin fixed server role can execute this stored procedure. Other users must be granted one of the following SQL Server Agent fixed database roles in the msdb database:

• SQLAgentUserRole

• SQLAgentReaderRole

• SQLAgentOperatorRole

Note that 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 cannot 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
