	ID	Gets the ID value that uniquely identifies the user-defined aggregate parameter.
	Name	Gets or sets a String value that specifies the name of the parameter. （覆盖 ParameterBase.Name。）
	Parent	Gets the UserDefinedAggregate object that is the parent of the UserDefinedAggregateParameter object.
	Properties	Gets a collection of Property objects that represent the object properties. （从 SqlSmoObject 继承。）
	State	Gets the state of the referenced object. （从 SmoObjectBase 继承。）
	Urn	Gets the Uniform Resource Name (URN) address value that uniquely identifies the object. （从 SqlSmoObject 继承。）
	UserData	Gets or sets user-defined data associated with the referenced object. （从 SmoObjectBase 继承。）

注释

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

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