MergePublication.AddMergeDynamicSnapshotJob 方法
定义
重要
一些信息与预发行产品相关,相应产品在发行之前可能会进行重大修改。 对于此处提供的信息,Microsoft 不作任何明示或暗示的担保。
添加一个快照代理作业,在使用参数化行筛选器时该代理作业为订阅服务器生成筛选的数据分区。
public:
void AddMergeDynamicSnapshotJob(Microsoft::SqlServer::Replication::MergeDynamicSnapshotJob ^ mergeDynamicSnapshotJob, Microsoft::SqlServer::Replication::ReplicationAgentSchedule ^ schedule);
public void AddMergeDynamicSnapshotJob (Microsoft.SqlServer.Replication.MergeDynamicSnapshotJob mergeDynamicSnapshotJob, Microsoft.SqlServer.Replication.ReplicationAgentSchedule schedule);
member this.AddMergeDynamicSnapshotJob : Microsoft.SqlServer.Replication.MergeDynamicSnapshotJob * Microsoft.SqlServer.Replication.ReplicationAgentSchedule -> unit
Public Sub AddMergeDynamicSnapshotJob (mergeDynamicSnapshotJob As MergeDynamicSnapshotJob, schedule As ReplicationAgentSchedule)
参数
- mergeDynamicSnapshotJob
- MergeDynamicSnapshotJob
已筛选的数据快照作业。
- schedule
- ReplicationAgentSchedule
与该作业相关联的计划。

注解
调用 AddMergeDynamicSnapshotJob 等效于执行 sp_adddynamicsnapshot_job。
方法 AddMergeDynamicSnapshotJob 只能由发布服务器上的 sysadmin 固定服务器角色的成员或发布数据库中 db_owner 固定数据库角色的成员调用。
