The name of the alert. @alert_name is sysname, with no default.

Removing a notification removes only the notification; the alert and the operator are left intact.
To run this stored procedure, users must be granted the sysadmin fixed server role.
The following example removes the notification sent to operator François Ajenstat when alert Test Alert occurs.
USE msdb;
GO
EXEC dbo.sp_delete_notification
@alert_name = 'Test Alert',
@operator_name = 'François Ajenstat' ;
GO
