How can I remove all transactional publications from a Microsoft Sql Server database?

Question

My database has a lot of subscribers to a lot of tables using Sql Server replication.

When I try to delete a table or delete a column on my database that takes part in a subscription on a published database the database migration fails.

Those subscribers check if they publication is still live and if not they re-subscribe.

I need to remove all publications from the current database via T-SQL so when I automate my database migrations delete columns or delete tables without the migration failing and needing manual intervention.

To delete all transactional publications from a server run the following script on the database you are connected:

declare @PublicationName varchar(max)
declare @ArticleName varchar(max)
declare @SubscriberServerName varchar(max)
declare @DestinationDb varchar(max)

IF OBJECT_ID('dbo.syspublications') is not null
BEGIN
      DECLARE db_cursor CURSOR FOR  
            select  
                   sp.name as PublicationName 
                   ,sa.name as TableName 
                  , UPPER(srv.srvname) as SubscriberServerName  
                  , dest_db as DestinationDb
                  from dbo.syspublications sp  
                  join dbo.sysarticles sa on sp.pubid = sa.pubid 
                  join dbo.syssubscriptions s on sa.artid = s.artid 
                  join master.dbo.sysservers srv on s.srvid = srv.srvid 

      OPEN db_cursor   
      FETCH NEXT FROM db_cursor INTO @PublicationName, @ArticleName, @SubscriberServerName, @DestinationDb

      WHILE @@FETCH_STATUS = 0   
      BEGIN   
            -- Dropping the transactional subscriptions
            exec sp_dropsubscription @publication = @PublicationName, @subscriber = @SubscriberServerName, @destination_db = @DestinationDb, @article = N'all'

            -- Dropping the transactional articles
            exec sp_dropsubscription @publication = @PublicationName, @article = @ArticleName, @subscriber = N'all', @destination_db = N'all'

            exec sp_droparticle @publication = @PublicationName, @article = @ArticleName, @force_invalidate_snapshot = 1

            -- Dropping the transactional publication
            exec sp_droppublication @publication = @PublicationName

            FETCH NEXT FROM db_cursor INTO @PublicationName, @ArticleName, @SubscriberServerName, @DestinationDb
      END   

      CLOSE db_cursor   
      DEALLOCATE db_cursor
END
