Transact-SQL syntax conventions

Syntax

sp_lookupcustomresolver
    [ @article_resolver = ] N'article_resolver'
    , [ @resolver_clsid = ] N'resolver_clsid' OUTPUT
    [ , [ @is_dotnet_assembly = ] is_dotnet_assembly OUTPUT ]
    [ , [ @dotnet_assembly_name = ] N'dotnet_assembly_name' OUTPUT ]
    [ , [ @dotnet_class_name = ] N'dotnet_class_name' OUTPUT ]
    [ , [ @publisher = ] N'publisher' ]
[ ; ]

Arguments

[ @article_resolver = ] N'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 = ] N'resolver_clsid' OUTPUT

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 an OUTPUT parameter of type nvarchar(50).

[ @is_dotnet_assembly = ] is_dotnet_assembly OUTPUT

Specifies the type of custom business logic that is being registered. @is_dotnet_assembly is an OUTPUT parameter of type bit.

  • 1 indicates that the custom business logic being registered is a business logic handler assembly.
  • 0 (default) indicates that it's a COM component.

[ @dotnet_assembly_name = ] N'dotnet_assembly_name' OUTPUT

The name of the assembly that implements the business logic handler. @dotnet_assembly_name is an OUTPUT parameter of type nvarchar(255).

[ @dotnet_class_name = ] N'dotnet_class_name' OUTPUT

The name of the class that overrides BusinessLogicModule to implement the business logic handler. @dotnet_class_name is an OUTPUT parameter of type nvarchar(255).

[ @publisher = ] N'publisher'

The name of the Publisher. @publisher is sysname, with a default of NULL. Use this parameter when the stored procedure isn't called from the Publisher. If not specified, it assumes that the local server is the Publisher.

Return code values

0 (success) or 1 (failure).

Remarks

sp_lookupcustomresolver is used in merge replication.

sp_lookupcustomresolver returns a NULL value for resolver_clsid when the component isn't 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.

Permissions

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