Свойства
Имя | Описание | |
---|---|---|
Count | Gets the number of objects in the referenced collection. (Производный от SmoCollectionBase.) | |
IsSynchronized | Gets the Boolean property value that specifies whether access to the collection is synchronized and therefore thread-safe. (Производный от SmoCollectionBase.) | |
Item[ ( [ ( Int32] ) ] ) | Gets a UserDefinedAggregate object in the collection by index number. | |
Item[ ( [ ( String] ) ] ) | Gets a UserDefinedAggregate object in the collection by name. | |
Item[ ( [ ( String, String] ) ] ) | Gets a UserDefinedAggregate object in the collection by name and schema. | |
Parent | Gets the Database object that is the parent of the UserDefinedAggregate object. | |
SyncRoot | Gets an object that can be used to synchronize access to the collection. (Производный от SmoCollectionBase.) |

Замечания
A UserDefinedAggregateCollection object can be used to gain access to a set of database user-defined aggregates. You can use the Item property to return a specific UserDefinedAggregate object.
