Remarks
You must run sp_syspolicy_delete_policy_category in the context of the msdb system database.
You must specify a value for @name or for @policy_category_id. Both can't be NULL. To obtain these values, query the msdb.dbo.syspolicy_policy_categories system view.
To delete a policy category, the category can't be referenced by any policies.
Permissions
Requires membership in the PolicyAdministratorRole fixed database role.
Important
Possible elevation of credentials: Users in the PolicyAdministratorRole role can create server triggers and schedule policy executions that can affect the operation of the instance of the Database Engine. For example, users in the PolicyAdministratorRole role can create a policy that can prevent most objects from being created in the Database Engine. Because of this possible elevation of credentials, the PolicyAdministratorRole role should be granted only to users who are trusted with controlling the configuration of the Database Engine.
Examples
The following example deletes a policy category that is named Finance.
EXEC msdb.dbo.sp_syspolicy_delete_policy_category @name = N'Finance';
