sql server 复制订阅的坑

公司系统更新，生产库新增加了几张表，需要同步到同步库，通过ssms 界面操作后，无法进行数据同步

<<案例总结>>

问题定义

=======

SQL Server 2012重新初始化订阅，启动代理，提示未生产快照

排查方法

=======

1. 首先我们检查了您环境中Publication端，确认没有同步的数据表已经加入发布，但是在订阅服务器的数库中无法获取同步数据。检查Agent没有报错信息。之后我们尝试使用如下语句重新将该Article从发布端移除。

Drop table from the publication. (This is just a sample, you can skip it, if you don’t want to drop this table, you can directly add a new article)

USE Pub_DB

exec sp_dropsubscription      @publication = N'backpub',

@article = N'test',

@subscriber = N'all',

@destination_db = N'all'

GO

exec sp_droparticle     @publication = N'backpub',

@article = N'test',

@force_invalidate_snapshot = 1

GO

1. 添加Article到发布端，语句如下所示：

USE Pub_DB

EXEC sp_addarticle @publication = N'backpub',

                   @article = N'test',

                   @source_object=N'test',

                   @force_invalidate_snapshot=1

GO

[ @force_invalidate_snapshot = ] force_invalidate_snapshot Acknowledges that the action taken by this stored procedure may invalidate an existing snapshot. force_invalidate_snapshot is a bit, with a default of 0.

0 specifies that adding an article does not cause the snapshot to be invalid. If the stored procedure detects that the change requires a new snapshot, an error occurs and no changes are made.

1 specifies that adding an article may cause the snapshot to be invalid, and if subscriptions exist that would require a new snapshot, gives permission for the existing snapshot to be marked as obsolete and a new snapshot to be generated.

关于sp_addarticle的详细信息，您可以参照如下链接;

https://docs.microsoft.com/zh-cn/sql/relational-databases/system-stored-procedures/sp-addarticle-transact-sql?view=sql-server-2017

1. 使用如下方法添加Article到订阅端。

<Optional>Then add the subscription for this new article using the following command

EXEC sp_addsubscription @publication = 'backpub',     --Publication name

                        @article = 'test',            --article name

                        @subscriber ='houdu533VM',    --this is the subscriber server nameinstance name

                        @destination_db = 'sub_back', --subscriber DB name

                        @reserved='Internal'

 

说明微软的ssms 界面还是不靠谱
