本主题介绍如何通过使用 SQL Server Management Studio、Transact-SQL 或复制管理对象 (RMO) 在 SQL Server 中删除请求订阅。

本主题内容

删除请求订阅，使用：

SQL Server Management Studio

Transact-SQL

复制管理对象 (RMO)

使用 SQL Server Management Studio

在发布服务器上删除请求订阅（从 SQL Server Management Studio 的“本地发布”文件夹中），或在订阅服务器上删除请求订阅（从“本地订阅”文件夹中）。删除订阅不会从订阅中删除对象或数据，必须对其手动删除。

在发布服务器上删除请求订阅

在 SQL Server Management Studio 中连接到发布服务器，然后展开服务器节点。
展开 “复制” 文件夹，再展开 “本地发布” 文件夹。
展开与要删除的订阅关联的发布。
右键单击该订阅，再单击 “删除”。
在确认对话框中，选择是否连接到订阅服务器以删除订阅信息。如果清除 “连接到订阅服务器” 复选框，则应在以后连接到订阅服务器以删除订阅信息。

在订阅服务器上删除请求订阅

在 SQL Server Management Studio 中连接到订阅服务器，然后展开服务器节点。
展开 “复制” 文件夹，再展开 “本地订阅” 文件夹。
右键单击要删除的订阅，再单击 “删除”。
在确认对话框中，选择是否连接到发布服务器以删除订阅信息。如果清除 “连接到发布服务器” 复选框，则应在以后连接到发布服务器以删除订阅信息。

“使用 Transact-SQL”

可以使用复制存储过程以编程方式删除请求订阅。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

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。
在发布数据库的发布服务器上，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

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。
在发布数据库的发布服务器上，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 (Transact-SQL)

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。

-- This script uses sqlcmd scripting variables. They are in the form
-- $(MyVariable). For information about how to use scripting variables  
-- on the command line and in SQL Server Management Studio, see the 
-- "Executing Replication Scripts" section in the topic

-- This is the batch executed at the Subscriber to drop 
-- a pull subscription to a transactional publication.
DECLARE @publication AS sysname;
DECLARE @publisher AS sysname;

SET @publisher = $(PubServer);
SET @publicationDB = N'AdventureWorks2022';

  @publisher_db = @publicationDB, 
  @publication = @publication;
GO

DECLARE @publication AS sysname;

USE [AdventureWorks2022]

以下示例删除对合并发布的请求订阅。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。

使用复制管理对象 (RMO)

可通过使用复制管理对象 (RMO) 以编程方式删除请求订阅。用于删除请求订阅的 RMO 类由该请求订阅所订阅的发布类型决定。

删除对快照发布或事务发布的请求订阅

使用 ServerConnection 类创建与订阅服务器和发布服务器的连接。
创建 TransPullSubscription 类的一个实例，并设置 PublicationName、 DatabaseName、 PublisherName以及 PublicationDBName 属性。使用步骤 1 中的订阅服务器连接来设置 ConnectionContext 属性。
检查 IsExistingObject 属性以确保该订阅存在。如果此属性的值为 false，则步骤 2 中所定义的订阅属性不正确或者该订阅不存在。
调用 Remove 方法。
使用步骤 1 中的发布服务器连接，创建 TransPublication 类的实例。指定 Name、 DatabaseName 和 ConnectionContext。
调用 LoadProperties 方法。如果该方法返回 false，则表示步骤 5 中指定的属性不正确，或者服务器中不存在发布。
调用 RemovePullSubscription 方法。将订阅服务器和订阅数据库的名称分别指定给 subscriber 和 subscriberDB 参数。

删除对合并发布的请求订阅

使用 ServerConnection 类创建与订阅服务器和发布服务器的连接。
创建 MergePullSubscription 类的一个实例，并设置 PublicationName、 DatabaseName、 PublisherName以及 PublicationDBName 属性。使用步骤 1 中的连接来设置 ConnectionContext 属性。
检查 IsExistingObject 属性以确保该订阅存在。如果此属性的值为 false，则步骤 2 中所定义的订阅属性不正确或者该订阅不存在。
调用 Remove 方法。
使用步骤 1 中的发布服务器连接，创建 MergePublication 类的实例。指定 Name、 DatabaseName 和 ConnectionContext。
调用 LoadProperties 方法。如果该方法返回 false，则表示步骤 5 中指定的属性不正确，或者服务器中不存在发布。
调用 RemovePullSubscription 方法。将订阅服务器和订阅数据库的名称分别指定给 subscriber 和 subscriberDB 参数。
