注解

Synchronize对返回TransSynchronizationAgent的对象调用该方法以同步订阅。

在检索SynchronizationAgent以同步订阅之前，应调用CommitPropertyChanges在服务器上保存任何属性更改。

If the subscription is created with a value of false for CreateSyncAgentByDefault, a Distribution Agent job for the subscription is not created. 可能需要在返回 TransSynchronizationAgent 的对象上指定其他属性，然后才能使用它来同步订阅。

SynchronizationAgent该属性只能由发布服务器上的固定服务器角色成员、发布数据库上的固定数据库角色的成员db_owner或发布访问列表的成员sysadmin (PAL) 订阅所属的发布检索。

检索 SynchronizationAgent 等效于执行 Transact-SQL) sp_helpsubscription (。
