该 Type 属性默认 LogBased 为事务发布或快照发布和 TableBased 合并发布。

Type在调用Create以在服务器上创建项目之前，必须设置该属性。在服务器上存在项目后，无法设置此属性。

Type属性可由发布服务器和订阅服务器 (的固定服务器角色的成员sysadmin检索，以便重新发布订阅服务器) 。也可以由发布数据库上的固定数据库角色的成员 db_owner 以及属于 PAL 成员的用户检索它。 MergeArticle对于对象，也可以由分发服务器上的固定数据库角色的成员replmonitor检索此属性。

Type属性可由发布服务器上的固定服务器角色的成员sysadmin设置。也可以由发布数据库上的固定数据库角色的成员 db_owner 设置。

检索 Type 相当于执行事务复制或快照复制的 Transact-SQL) sp_helparticle (，或者执行用于合并复制的 Transact-SQL) sp_helpmergearticle (。
