MakePullSubscriptionWellKnown(String, String, SubscriptionSyncType, TransSubscriberType)
在发布服务器上注册请求订阅。
public:
void MakePullSubscriptionWellKnown(System::String ^ subscriber, System::String ^ subscriptionDB, Microsoft::SqlServer::Replication::SubscriptionSyncType syncType, Microsoft::SqlServer::Replication::TransSubscriberType subscriberType);
public void MakePullSubscriptionWellKnown (string subscriber, string subscriptionDB, Microsoft.SqlServer.Replication.SubscriptionSyncType syncType, Microsoft.SqlServer.Replication.TransSubscriberType subscriberType);
member this.MakePullSubscriptionWellKnown : string * string * Microsoft.SqlServer.Replication.SubscriptionSyncType * Microsoft.SqlServer.Replication.TransSubscriberType -> unit
Public Sub MakePullSubscriptionWellKnown (subscriber As String, subscriptionDB As String, syncType As SubscriptionSyncType, subscriberType As TransSubscriberType)
参数
- syncType
- SubscriptionSyncType
一个 SubscriptionSyncType 对象值,该值指定订阅同步的执行方式。
- subscriberType
- TransSubscriberType
一个 TransSubscriberType 对象值,该值指定在订阅服务器启动对项目映像数据的更改时的订阅行为。

注解
创建请求订阅时,必须在发布服务器上调用 MakePullSubscriptionWellKnown 。
使用 EnumSubscriptions 确定订阅是否已在发布服务器上注册。 如果注册存在, MakePullSubscriptionWellKnown 则会在服务器上生成错误。
MakePullSubscriptionWellKnown方法只能由发布服务器上的固定服务器角色的成员sysadmin
、发布数据库上的固定数据库角色的成员db_owner
或发布访问列表中的用户 (PAL) 调用。
调用 MakePullSubscriptionWellKnown 等效于为请求订阅执行 sp_addsubscription 。
