删除请求订阅

2017-03-06

本主题介绍如何使用 SQL Server Management Studio、Transact-SQL 或复制管理对象（RMO）在 SQL Server 2014 中删除请求订阅。

本主题内容

若要删除请求订阅，请使用：

SQL Server Management Studio

Transact-SQL

复制管理对象 (RMO)

使用 SQL Server Management Studio

从 SQL Server Management Studio 中的 本地发布 文件夹或从订阅服务器中的 本地订阅 文件夹删除发布服务器的提取订阅。删除订阅不会从订阅中删除对象或数据;必须手动删除它们。

在发布服务器上删除拉取订阅

在 SQL Server Management Studio 中连接到发布者，然后展开该服务器节点。
展开 “复制 ”文件夹，然后展开 “本地发布” 文件夹。
展开与该订阅关联的出版物，以便删除。
右键单击订阅，然后单击“ 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，则应稍后连接到订阅服务器以删除信息。

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，然后展开 “本地订阅 ”文件夹。
右键单击要删除的订阅，然后单击“ 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，则应稍后连接到发布服务器以删除信息。

使用 Transact-SQL

可以使用复制存储过程以编程方式删除拉取订阅。使用的存储过程将取决于订阅所属的发布类型。

删除快照或事务发布的拉式订阅

在订阅数据库上，执行sp_droppullsubscription（Transact-SQL）。指定 @publication、 @publisher和 @publisher_db。
在发布者的发布数据库上，执行sp_dropsubscription（Transact-SQL）。指定 @publication 和 @subscriber。为@article指定all的值。（可选）如果无法访问分发服务器，请为@ignore_distributor指定值 1 以删除订阅，而无需在分发服务器上删除相关对象。

删除合并发布的拉取订阅

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。
在发布服务器上，对发布数据库执行sp_dropmergesubscription（Transact-SQL）。指定 @publication、 @subscriber和 @subscriber_db。为@subscription_type指定值为pull。（可选）如果无法访问分发服务器，请为@ignore_distributor指定值 1 以删除订阅，而无需在分发服务器上删除相关对象。

示例 (Transact-SQL)

以下示例删除事务发布中的拉取订阅。第一批在订阅服务器上执行，第二批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
-- "Programming Replication Using System Stored Procedures".

-- 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'AdventureWorks2012';

USE [AdventureWorks2012Replica]

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

DECLARE @publication AS sysname;

USE [AdventureWorks2012]

  @article = N'all',
  @subscriber = @subscriber;
GO

以下示例删除合并发布中的拉式订阅。第一批在订阅服务器上执行，第二批在发布服务器上执行。

USE [AdventureWorks2012]
EXEC sp_dropmergesubscription 
  @publication = @publication, 
  @subscriber = @subscriber, 
  @subscriber_db = @subscriptionDB;
GO

使用复制管理对象 (RMO)

可以通过使用复制管理对象（RMO）以编程方式删除拉取式订阅。用于删除请求订阅的 RMO 类取决于请求订阅订阅的发布类型。

删除关于快照或事务性发布的拉取订阅

使用 ServerConnection 类创建与订阅服务器和发布服务器的连接。
创建TransPullSubscription类的实例，并设置PublicationName、DatabaseName、PublisherName和PublicationDBName属性。使用步骤 1 中的订阅服务器连接设置 ConnectionContext 属性。
检查属性 IsExistingObject 以验证订阅是否存在。如果此属性的值是 false，则步骤 2 中的订阅属性定义不正确或订阅不存在。
调用 Remove 方法。
使用步骤 1 中的 Publisher 连接创建 TransPublication 类的实例。指定 Name和 DatabaseName ConnectionContext。
调用 LoadProperties 方法。如果此方法返回 false，则步骤 5 中指定的属性不正确，或者服务器上不存在发布。
调用 RemovePullSubscription 方法。为订阅服务器和 subscriberDB 参数指定订阅服务器和订阅数据库的名称。

删除合并发布的拉取订阅

使用 ServerConnection 类创建与订阅服务器和发布服务器的连接。
创建类的MergePullSubscription实例，并设置PublicationName、DatabaseName、PublisherName和PublicationDBName属性。使用步骤 1 中的连接设置 ConnectionContext 属性。
检查属性 IsExistingObject 以验证订阅是否存在。如果此属性的值是 false，则步骤 2 中的订阅属性定义不正确或订阅不存在。
调用 Remove 方法。
使用步骤 1 中的 Publisher 连接创建 MergePublication 类的实例。指定 Name和 DatabaseName ConnectionContext。
调用 LoadProperties 方法。如果此方法返回 false，则步骤 5 中指定的属性不正确，或者服务器上不存在发布。
调用 RemovePullSubscription 方法。为订阅服务器和 subscriberDB 参数指定订阅服务器和订阅数据库的名称。
