注解

如果拉取订阅创建时值为falseCreateSyncAgentByDefault，默认情况下，订阅的合并代理作业不会被创建，调用SynchronizeWithJob会引发异常。

如果任务正在运行，就调用 StopSynchronizationJob 停止该方法。

如果 SQL Server 代理 服务未运行，作业无法启动。 此外，如果没有生成快照，运行代理作业可能无法同步订阅。

如果你在该实例MergeSubscription上设置了额外的属性，请先调用CommitPropertyChanges。SynchronizeWithJob

SynchronizeWithJob该方法只能由订阅用户的系统管理员固定服务器角色成员或订阅数据库中db_owner固定数据库角色的成员调用。
