[ @article_resolver = ] 'article_resolver'

Specifies the name of the custom business logic being unregistered. article_resolver is nvarchar(255), with no default. If the business logic being removed is a COM component, then this parameter is the friendly name of the component. If the business logic is a Microsoft .NET Framework assembly, then this parameter is the name of the assembly.

[ @resolver_clsid= ] 'resolver_clsid' OUTPUT

Is the CLSID value of the COM object associated with the name of the custom business logic specified in the article_resolver parameter. resolver_clsid is nvarchar(50), with a default of NULL.

[ @is_dotnet_assembly= ] 'is_dotnet_assembly' OUTPUT

Specifies the type of custom business logic that is being registered. is_dotnet_assembly is bit, with a default of 0. 1 indicates that the custom business logic being registered is a business logic handler Assembly; 0 indicates that it is a COM component.

[ @dotnet_assembly_name= ] 'dotnet_assembly_name' OUTPUT

Is the name of the assembly that implements the business logic handler. dotnet_assembly_name is nvarchar(255), with a default value of NULL.

[ @dotnet_class_name= ] 'dotnet_class_name' OUTPUT

Is the name of the class that overrides BusinessLogicModule to implement the business logic handler. dotnet_class_name is nvarchar(255), with a default value of NULL.

[ @publisher= ] 'publisher'

sp_lookupcustomresolver is used in merge replication.

sp_lookupcustomresolver returns a NULL value for resolver_clsid when the component is not registered at the Distribution and a value of "00000000-0000-0000-0000-000000000000" when the registration belongs to a .NET Framework assembly registered as a business logic handler.

sp_lookupcustomresolver is called by sp_addmergearticle and sp_changemergearticle to validate the specified article_resolver.

Only members of the db_owner fixed database role on the publication database can execute sp_lookupcustomresolver.
