Comentários

To get UserDefinedAggregate object properties, users can be a member of the public fixed server role.

To set UserDefinedAggregate object properties, users must have CREATE AGGREGATE permission on the database and also REFERENCES permission on the specified assembly.

To create a user-defined aggregate, users must have DROP AGGREGATE permission on the database or ALTER permission on the user-defined aggregate.

To grant, deny, or revoke permission on the user-defined aggregate to other users, users must have CONTROL permission on the user-defined aggregate.

Segurança de thread

Qualquer membro público static (Shared no Visual Basic) desse tipo é seguro para threads. Não há garantia de que qualquer membro de instância seja seguro para threads.
