注解

调用 Synchronize 返回 TransSynchronizationAgent 对象的方法来同步订阅。

在取用SynchronizationAgent前调用CommitPropertyChanges服务器上保存所有属性变更以同步订阅。

如果拉取订阅创建时值为falseCreateSyncAgentByDefault，默认情况下，订阅的分发代理作业不会被创建。 你可能需要在返回 TransSynchronizationAgent 的对象上指定额外的属性，才能用来同步订阅。

SynchronizationAgent该属性只能由订阅者中固定服务器角色的成员sysadmin或订阅数据库中固定数据库角色的成员db_owner检索。

取回 SynchronizationAgent 财产等同于执行 sp_helppullsubscription。
