sp_addmergepullsubscription (Transact-SQL)
添加对合并发布的请求订阅。此存储过程在订阅服务器的订阅数据库中执行。
语法
sp_addmergepullsubscription [ @publication= ] 'publication'
[ , [ @publisher= ] 'publisher' ]
[ , [ @publisher_db = ] 'publisher_db' ]
[ , [ @subscriber_type= ] 'subscriber_type' ]
[ , [ @subscription_priority= ] subscription_priority ]
[ , [ @sync_type= ] 'sync_type' ]
[ , [ @description= ] 'description' ]
参数
[ @publication = ] 'publication'
发布的名称。publication 的数据类型为 sysname,无默认值。[ @publisher = ] 'publisher'
发布服务器的名称。Publisher 的数据类型为 sysname,默认值为本地服务器名称。发布服务器必须为有效服务器。[ @publisher_db=] 'publisher_db'
发布服务器数据库的名称。publisher_db 的数据类型为 sysname,默认值为 NULL。[ @subscriber_type=] 'subscriber_type'
订阅服务器的类型。subscriber_type 的数据类型为 nvarchar(15),且可以是 global、local 或 anonymous。在 SQL Server 2005 及更高版本中,本地订阅称为客户端订阅,全局订阅称为服务器订阅。有关详细信息,请参阅合并复制如何检测和解决冲突中的“订阅类型”部分。[ @subscription_priority=] subscription_priority
订阅优先级。subscription_priority的数据类型为 real,默认值为 NULL。对于本地订阅和匿名订阅,优先级为 0.0。在检测到冲突时,默认冲突解决程序将使用该优先级来选取入选方。全局订阅服务器的订阅优先级必须低于 100,因为 100 是发布服务器的优先级。[ @sync_type=] 'sync_type'
订阅的同步类型。sync_type的数据类型为 nvarchar(15),默认值为 automatic。可以为 automatic 或 none。如果为 automatic,则表示已发布表的架构和初始数据将首先传输到订阅服务器。如果为 none,则假定订阅服务器已拥有已发布表的架构和初始数据。始终会传输系统表和数据。注意 建议不要将值指定为 none。有关详细信息,请参阅初始化合并订阅(不使用快照)。
[ @description =] 'description'
对该请求订阅的简短说明。description的数据类型为 nvarchar(255),默认值为 NULL。此值由复制监视器显示在“友好名称”列中,该列可以用来对所监视发布的订阅进行排序。
返回代码值
0(成功)或 1(失败)
注释
sp_addmergepullsubscription 用于合并复制。
如果使用 SQL Server 代理对订阅进行同步处理,则 sp_addmergepullsubscription_agent 存储过程必须在订阅服务器上运行,才能创建与发布同步的代理和作业。
