The possibility of creating custom aggregation functions can be very useful when you want to create an aggregate that isn t included with SQL Server (such as a product aggregate) or to create an aggregate function that can handle a custom CLR UDT. When creating a CLR user-defined aggregate, you must create an entire CLR type (either class or struct) rather than just one or two methods as with the previous CLR objects. This is because the aggregate needs to be able to do a few things, including the following:

//Register object as a singleton server-activated object RemotingConfiguration.RegisterWellKnownServiceType (typeof(Server.MyRemoteClass), "MyRemotingObject", WellKnownObjectMode.Singleton); }

Dim aReader As New System.IO.StreamReader(OpenFileDialog1.FileName)

else if (args[0] == "C")

add another value to the calculation For each value that needs to be added to the calculation, the Accumulate method is called. combine itself with another instance of the same aggregate function

//Register object as a client-activated object RemotingConfiguration.RegisterActivatedServiceType (typeof(Server.MyRemoteClass));

aReader.Close()

Before we explore more details of user-defined aggregates, take a few moments to read through the following example of CLR code, which defines a mathematical product aggregate. The result of this aggregate is all inputs multiplied together (such as 5 * 10 * 15 = 750). To add some extra functionality to this aggregate, we have included a second

//Register object as a singleton server-activated object RemotingConfiguration.RegisterWellKnownServiceType (typeof(Server.MyRemoteClass), "MyRemotingObject", WellKnownObjectMode.Singleton); }

//Unregister all of our channels to cleanup ChannelServices.UnregisterChannel(tcpChannel); ChannelServices.UnregisterChannel(httpChannel); ChannelServices.UnregisterChannel(ipcChannel); }

parameter that tells the aggregate whether or not to include zeros in the calculation (because the inclusion of a zero would always result in an aggregate of zero). The possibility of having multiple parameters in user-defined aggregates was added in SQL Server 2008. There are quite a few observations to make about this code:

strings = s.Split(ControlChars.CrLf)

The RemoteConfiguration class can be used to programmatically configure your remote server application. With this class you can set basic properties for your remote object such as the application name. Server-activated objects are registered with the RegisterWellKnownServiceType method. Client-activated objects are registered on the server end with the RegisterActivatedServiceType method. If you have multiple versions of a remote object available and you want to specify a version other than the latest, you need to specify the version attribute when registering the object. Communication channels can be registered with the RegisterChannel method and a reference to the particular channel class. This can be used to set properties such as port number and formatter type.

In this example, the SqlUserDefinedAggregate attribute tells SQL Server that we will manually manage serializing the aggregate (if necessary) by specifying the format to be user-defined (Format.UserDefined). The attribute also tells SQL Server that it should return NULL if no values are included in the aggregation (IsNullIfEmpty = True), that the aggregate cares about duplicates (IsInvariantToDuplicates = False), doesn t care about NULL values (IsInvariantToNulls = True), and doesn t care about the order of the input (IsInvariantToOrder = True). Finally, the attribute tells SQL Server that the maximum storage space used when serializing this aggregate is 19 bytes (16 bytes for the decimal value and 1 byte each for three Boolean values). The SqlFacet attribute is used a few times throughout the code to specify the precision and scale of the SqlDecimal type. The IBinarySerialize interface must be implemented because we used the user-defined format when defining the aggregate. You can also choose to use the native format; however, that does not work in this example because the decimal data type here is not supported by native serialization. The IBinarySerialize.Write method is called by SQL Server to serialize the instance during execution, if needed. The IBinarySerialize.Read method is called by SQL Server to deserialize the instance during execution, if needed.
