Remove Replication

Hi all,

I try to remove a replication with from my MS SQL 2000


DECLARE @publication AS sysname
DECLARE @publicationDB AS sysname
SET @publication = N'MyDB_merge'
SET @publicationDB = N'MyDB'
-- Remove the merge publication.
USE [MyDB]
EXEC sp_dropmergepublication @publication = @publication;
-- Remove replication objects from the database.
USE master
EXEC sp_replicationdboption
@dbname = @publicationDB,
@optname = N'merge publish',
@value = N'false'
GO


but seems to do nothing, how many time cost this operation?
MSSQL search something ?

There is a solution for remove rapidly a replication from my database.

Thank's a lot bye
Bye
