備註

只有 Microsoft .NET Framework 2.0 版支援此命名空間、類別或成員。

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.
