UserDefinedAggregate Class

The UserDefinedAggregate object represents a Microsoft SQL Server user-defined aggregate.

Namespace: Microsoft.SqlServer.Management.Smo
Assembly: Microsoft.SqlServer.Smo (in microsoft.sqlserver.smo.dll)

public sealed class UserDefinedAggregate : ScriptSchemaObjectBase, IObjectPermission, ICreatable, IDroppable, 
	IExtendedProperties, IScriptable
public final class UserDefinedAggregate extends ScriptSchemaObjectBase implements IObjectPermission, ICreatable, 
	IDroppable, IExtendedProperties, IScriptable
public final class UserDefinedAggregate extends ScriptSchemaObjectBase implements IObjectPermission, ICreatable, 
	IDroppable, IExtendedProperties, IScriptable

This namespace, class, or member is supported only in version 2.0 of the Microsoft .NET Framework.

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.


Any public static (Shared in Microsoft Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
