上篇中说了通过SQL JOB的方式对数据库的同步,这一节作为上一节的延续介绍通过发布订阅的方式实现数据库之间的同步操作。发布订阅份为两个步骤:1、发布。2订阅。首先在 数据源数据库服务器上对需要同步的数据进行发布,然后在目标数据库服务器上对上述发布进行订阅。发布可以发布一张表的部分数据,也可以对整张表进行发布。 下面分别介绍发布、订阅的过程。
1、发布。发布需要用实际的服务器名称,不能使用服务器的IP地址进行。能发布的信息包括【表】、【存储过程】、【用户函数】如果使用IP会有错误,如下图:
具体发布过程如下:
1、找到数据库服务器下的【复制】--【本地发布】,选择【新建发布】。如下图:
2.选择待发布的数据库。如下图:
3、选择发布类型。这里选择的默认类型【快照发布】。几种发布类型的区别,SQL SERVER都在下面给出了说明。如下图:
4、选择待发布的类容。如下图:
上图中右侧就是筛选的SQL语句。
5、设置快照代理。如下图:
更改同步频率如下图:
6、设置代理安全性。如下图:
7、填写发布名称
8、完成发布。如下图:
2、订阅。订阅是对数据库发布的快照进行同步,将发布的数据源数据同步到目标数据库。具体订阅过程如下;
1、找到数据库服务器下的【复制】--【本地订阅】,选择【新建订阅】。如下图:
2、选择订阅的发布。如下图:
3、选择分发代理的位置;如下图:
4、选择订阅服务器上的存放同步过来的数据的一个或者多个目标数据库。如下图:
若要添加多个订阅数据库,则点击【添加订阅服务器】。如下图:
5、设置分发代理的安全性。如下图:
6、设置同步计划。如下图:
7、完成订阅。如下图:
这样就完成了发布与订阅的整个流程。
这里,和上节一起就介绍完了SQL Server数据库同步的两种方式,希望对你有用。

Go language is an efficient, concise and easy-to-learn programming language. It is favored by developers because of its advantages in concurrent programming and network programming. In actual development, database operations are an indispensable part. This article will introduce how to use Go language to implement database addition, deletion, modification and query operations. In Go language, we usually use third-party libraries to operate databases, such as commonly used sql packages, gorm, etc. Here we take the sql package as an example to introduce how to implement the addition, deletion, modification and query operations of the database. Assume we are using a MySQL database.

Hibernate polymorphic mapping can map inherited classes to the database and provides the following mapping types: joined-subclass: Create a separate table for the subclass, including all columns of the parent class. table-per-class: Create a separate table for subclasses, containing only subclass-specific columns. union-subclass: similar to joined-subclass, but the parent class table unions all subclass columns.

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

HTML cannot read the database directly, but it can be achieved through JavaScript and AJAX. The steps include establishing a database connection, sending a query, processing the response, and updating the page. This article provides a practical example of using JavaScript, AJAX and PHP to read data from a MySQL database, showing how to dynamically display query results in an HTML page. This example uses XMLHttpRequest to establish a database connection, send a query and process the response, thereby filling data into page elements and realizing the function of HTML reading the database.

To handle database connection errors in PHP, you can use the following steps: Use mysqli_connect_errno() to obtain the error code. Use mysqli_connect_error() to get the error message. By capturing and logging these error messages, database connection issues can be easily identified and resolved, ensuring the smooth running of your application.

How to use MySQLi to establish a database connection in PHP: Include MySQLi extension (require_once) Create connection function (functionconnect_to_db) Call connection function ($conn=connect_to_db()) Execute query ($result=$conn->query()) Close connection ( $conn->close())

Using the database callback function in Golang can achieve: executing custom code after the specified database operation is completed. Add custom behavior through separate functions without writing additional code. Callback functions are available for insert, update, delete, and query operations. You must use the sql.Exec, sql.QueryRow, or sql.Query function to use the callback function.

With the rise of short video platforms, users have become an important way for many people to record their lives and showcase their talents.
