注释

SQL Server Agent categories provide optional attributes that are used to distinguish groups of alerts.

With the AlertCategory object, you can:

  • Create groupings for alerts.

The category name must be unique.

To get AlertCategory object properties, users must be a member of SQLAgentUserRole database role on the MSDB database or be a member of the sysadmin fixed server role.

To set AlertCategory object properties, users must be a member of the sysadmin fixed server role.

To create or drop an alert category, users must be a member of the sysadmin fixed server role.
