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.
