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 中删除发布。
本主题内容
若要删除发布,请使用:
使用 SQL Server Management Studio
从 SQL Server Management Studio 中的 “本地发布” 文件夹中删除发布。
删除发布的文件
在 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,然后展开 “本地发布” 文件夹。
右键单击要删除的出版物,然后单击“ 删除”。
使用 Transact-SQL
可以使用复制存储过程以编程方式删除出版物。 使用的存储过程取决于要删除的发布类型。
注释
删除发布不会从发布数据库中删除已发布的对象,也不会从订阅数据库中删除相应的对象。 如有必要,请使用 DROP <object>
命令手动删除这些对象。
删除快照或事务性发布
执行下列操作之一:
若要删除单个发布,请在发布服务器上对发布数据库执行 sp_droppublication 。
若要删除已发布数据库中的所有发布并删除所有复制对象,请在发布服务器上执行 sp_removedbreplication 。 指定
tran
作为@type的值。 (可选)如果无法访问分发服务器或数据库的状态可疑或脱机,请为 @force 指定值 1。 (可选)如果未对发布数据库执行 sp_removedbreplication ,请为 @dbname 指定数据库的名称。注释
为@force指定值1可能导致与复制相关的发布对象保留在数据库中。
(可选)如果此数据库没有其他发布,请执行 sp_replicationdboption(Transact-SQL), 以使用快照或事务复制禁用当前数据库的发布。
(可选)在订阅数据库上的订阅服务器,执行sp_subscription_cleanup以清除订阅数据库中的剩余复制元数据。
删除合并发布
执行下列操作之一:
若要删除单个发布,请在发布服务器上对发布数据库执行sp_dropmergepublication(Transact-SQL)。
若要删除已发布数据库中的所有发布内容并移除所有复制对象,请在发布服务器上执行 sp_removedbreplication 。 指定
merge
作为@type的值。 (可选)如果无法访问分发服务器或数据库的状态可疑或脱机,请为 @force 指定值 1。 (可选)如果未对发布数据库执行 sp_removedbreplication ,请为 @dbname 指定数据库的名称。注释
为@force指定值 1 可能会导致与复制相关的发布对象保留在数据库中。
(可选)如果此数据库没有其他发布,请执行 sp_replicationdboption(Transact-SQL),以通过合并复制禁用当前数据库的发布功能。
(可选)在订阅数据库的订阅服务器上,执行 sp_mergesubscription_cleanup(Transact-SQL) 以删除订阅数据库中的任何剩余复制元数据。
示例 (Transact-SQL)
此示例演示如何删除事务发布并禁用数据库的事务发布。 此示例假定以前删除了所有订阅。 有关详细信息,请参阅“删除请求订阅”或删除推送订阅。
DECLARE @publicationDB AS sysname;
DECLARE @publication AS sysname;
SET @publicationDB = N'AdventureWorks';
SET @publication = N'AdvWorksProductTran';
-- Remove a transactional publication.
USE [AdventureWorks2012]
EXEC sp_droppublication @publication = @publication;
-- Remove replication objects from the database.
USE [master]
EXEC sp_replicationdboption
@dbname = @publicationDB,
@optname = N'publish',
@value = N'false';
GO
此示例演示如何删除合并发布并禁用数据库的合并发布。 此示例假定以前删除了所有订阅。 有关详细信息,请参阅“删除请求订阅”或删除推送订阅。
DECLARE @publication AS sysname
DECLARE @publicationDB AS sysname
SET @publication = N'AdvWorksSalesOrdersMerge'
SET @publicationDB = N'AdventureWorks'
-- Remove the merge publication.
USE [AdventureWorks]
EXEC sp_dropmergepublication @publication = @publication;
-- Remove replication objects from the database.
USE master
EXEC sp_replicationdboption
@dbname = @publicationDB,
@optname = N'merge publish',
@value = N'false'
GO
使用复制管理对象 (RMO)
可以通过使用复制管理对象(RMO)以编程方式删除发布。 用于删除发布的 RMO 类取决于删除的发布类型。
删除快照或事务发布
使用 ServerConnection 类创建与发布服务器的连接。
创建 TransPublication 类的一个实例。
设置发布的Name和DatabaseName属性,并将ConnectionContext属性设置为步骤 1 中创建的连接。
检查属性 IsExistingObject 以验证发布是否存在。 如果此属性
false
的值为,则步骤 3 中的发布属性定义不正确或发布不存在。调用 Remove 方法。
(可选)如果此数据库没有其他事务发布,则可以将此数据库设置为禁用事务发布,如下所示:
创建 ReplicationDatabase 类的一个实例。 将 ConnectionContext 属性设置为步骤 1 中的 ServerConnection 实例。
调用 LoadProperties 方法。 如果此方法返回
false
,请确认数据库存在。将 EnabledTransPublishing 属性设置为
false
。调用 CommitPropertyChanges 方法。
关闭连接。
删除合并出版物
使用 ServerConnection 类创建与发布服务器的连接。
创建 MergePublication 类的一个实例。
设置发布的Name和DatabaseName属性,并将ConnectionContext属性设置为步骤 1 中创建的连接。
检查属性 IsExistingObject 以验证发布是否存在。 如果此属性
false
的值为,则步骤 3 中的发布属性定义不正确或发布不存在。调用 Remove 方法。
(可选)如果此数据库不存在其他合并发布,则可以禁用数据库进行合并发布,如下所示:
创建 ReplicationDatabase 类的一个实例。 将 ConnectionContext 属性设置为步骤 1 中的 ServerConnection 实例。
调用 LoadProperties 方法。 如果此方法返回
false
,请验证数据库是否存在。将 EnabledMergePublishing 属性设置为
false
。调用 CommitPropertyChanges 方法。
关闭连接。
示例 (RMO)
以下示例删除事务性发布。 如果此数据库不存在其他事务发布,事务发布也会被禁止。
