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.
Thread Safety
此类型的任何公共静态(Microsoft Visual Basic 中的 Shared)成员在多线程操作中是安全的。但不保证所有实例成员都是线程安全的。
