Supports DROP TABLE DDL for articles that are included in transactional replication in SQL Server 2014 or in SQL Server 2016 SP1

Dotyczy: SQL Server 2014 DeveloperSQL Server 2014 DeveloperSQL Server 2014 Enterprise

This article describes an improvement that allows a table that's included as an article in transactional replication publication to be dropped from the database and the publication(s). A table can be dropped only if the allow_drop property is set to TRUE on all the publications that have the table(s) as an article. If the property is set to FALSE for any of the publications that contain the article, then the DROP TABLE operation will fail and report that replicated articles can't be dropped.

If a DROP TABLE DDL is supported by the publication(s), then the DROP TABLE operation will drop the table from the publication and the database. The log reader agent will post a cleanup command for the distribution database of the dropped table and do the cleanup of the publisher metadata. If the log reader hasn't processed all the log records that refer to the dropped table, then it will ignore new commands that are associated with the dropped table. Already processed records will be delivered to distribution database. They may be applied on Subscriber database if the Distribution Agent processes them before Log Reader cleans up the obsolete (dropped) article(s).

Command to enable drop table support for a publication:
exec sp_changepublication @publication = '<Publication Name>', @property = 'allow_drop', @value = 'true' 
Command to enable drop table support while you're creating a publication:

exec sp_addpublication @publication = '<Publication Name>', ..., @allow_drop = N'true' 
The default value of the allow_drop property is set to False.

About Service packs for SQL Server

Service packs are cumulative. Each new service pack contains all the fixes that are in previous service packs, together with any new fixes. Our recommendation is to apply the latest service pack and the latest cumulative update for that service pack. You don't have to install a previous service pack before you install the latest service pack. Use Table 1 in the following article for finding more information about the latest service pack and latest cumulative update.
