如何删除请求订阅（复制 Transact-SQL 编程）

请求订阅可以使用复制存储过程以编程的方式进行删除。 所用的存储过程取决于订阅所属的发布的类型。

删除对快照发布或事务发布的请求订阅

  1. 在订阅服务器上，对订阅数据库执行sp_droppullsubscription (Transact-SQL)。 指定 @publication、@publisher 和 @publisher_db。

  2. 在发布服务器上，对发布数据库执行 sp_dropsubscription (Transact-SQL)。 指定 @publication 和 @subscriber。 将 @article 的值指定为 all。 （可选）如果无法访问分发服务器，将 @ignore_distributor 的值指定为 1，以便在不删除分发服务器上相关对象的情况下删除订阅。

删除对合并发布的请求订阅

  1. 在订阅服务器上，对订阅数据库执行 sp_dropmergepullsubscription (Transact-SQL)。 指定 @publication、@publisher 和 @publisher_db。

  2. 在发布服务器上，对发布数据库执行 sp_dropmergesubscription (Transact-SQL)。 指定 @publication、@subscriber 和 @subscriber_db。 将 @subscription_type 的值指定为 pull。 （可选）如果无法访问分发服务器，将 @ignore_distributor 的值指定为 1，以便在不删除分发服务器上相关对象的情况下删除订阅。

示例

以下示例删除对事务发布的请求订阅。 第一个批处理在订阅服务器上执行，第二个批处理在发布服务器上执行。
