You cannot drop the rowguid column from articles in merge publications or the mstran_repl_version column from articles in transactional publications that support updating subscriptions, because they are used by replication.

• 无法从合并发布的项目中删除rowguid列,也不能从支持更新订阅的事务性发布的项目中删除mstran_repl_version列,因为这些列由复制使用。
