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。

MySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.

Efficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.

Use the EXPLAIN command to analyze the execution plan of MySQL queries. 1. The EXPLAIN command displays the execution plan of the query to help find performance bottlenecks. 2. The execution plan includes fields such as id, select_type, table, type, possible_keys, key, key_len, ref, rows and Extra. 3. According to the execution plan, you can optimize queries by adding indexes, avoiding full table scans, optimizing JOIN operations, and using overlay indexes.

Subqueries can improve the efficiency of MySQL query. 1) Subquery simplifies complex query logic, such as filtering data and calculating aggregated values. 2) MySQL optimizer may convert subqueries to JOIN operations to improve performance. 3) Using EXISTS instead of IN can avoid multiple rows returning errors. 4) Optimization strategies include avoiding related subqueries, using EXISTS, index optimization, and avoiding subquery nesting.

Methods for configuring character sets and collations in MySQL include: 1. Setting the character sets and collations at the server level: SETNAMES'utf8'; SETCHARACTERSETutf8; SETCOLLATION_CONNECTION='utf8_general_ci'; 2. Create a database that uses specific character sets and collations: CREATEDATABASEexample_dbCHARACTERSETutf8COLLATEutf8_general_ci; 3. Specify character sets and collations when creating a table: CREATETABLEexample_table(idINT

To safely and thoroughly uninstall MySQL and clean all residual files, follow the following steps: 1. Stop MySQL service; 2. Uninstall MySQL packages; 3. Clean configuration files and data directories; 4. Verify that the uninstallation is thorough.

Renaming a database in MySQL requires indirect methods. The steps are as follows: 1. Create a new database; 2. Use mysqldump to export the old database; 3. Import the data into the new database; 4. Delete the old database.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
