Тип: Microsoft.SqlServer.Replication. . :: . .BusinessLogicHandler
A BusinessLogicHandler object that represents the business logic handler that is being registered.
Замечания
The business logic handler must be registered at the Distributor (and at the Subscriber in the case of a pull subscription). However, the assembly that implements the business logic handler need only be installed on the server on which the Merge Agent runs.
The RegisterBusinessLogicHandler(BusinessLogicHandler) method can only be called by members of the sysadmin fixed server role and members of the db_owner fixed database role
Calling RegisterBusinessLogicHandler(BusinessLogicHandler) is equivalent to executing sp_registercustomresolver.
The RegisterBusinessLogicHandler(BusinessLogicHandler) method can only be used with servers that are running on SQL Server 2005 and later versions.
