开个单章，记录遇到的SQL Server的问题及解决办法，方便自已以后回顾。

1)SQL Server服务突然无法启动
问题描述：之前一直没有问题，突然某天无法启动了
解决办法：查看控制面板->管理工具->事件查看器，发现是因为登录失败而无法启动。
找到原因，就简单了，从服务中找到SQL Server的服务，，右键属性，然后打开"登录"tab页，选上本地系统，就OK了。
该问题多半是因为更改了操作系统的登录密码造成了。所以要更新sqlserver的账户登录密码。当然，最好的方式就是就是上面的觪决办法了。
这样以后就会自动更新。
2)17051错误
代码为17051:查了半天，才知道这是评估期过。用有效的序列号更新下就行了。
3)报错代码126
把via协议禁用了，再启动服务，就OK了
4)错误 233 的解决办法
打开'程序'-'所有程序'-'Microsoft SQL Server '-'配置工具'-'SQL Server 配置管理器',在弹出的窗体中，找到'SQL Server 网络配置',把'MSSQLSERVER的协议'下的"Named Pipes"和"TCP/IP"启动，然后重新启动Microsoft SQL Server
5)消息 15466,级别 16,状态 2,过程 sp_addlinkedsrvlogin,第 91 行解密过程中出错。
消息 15185,级别 16,状态 1,过程 sp_addlinkedsrvlogin,第 98 行
没有从远程服务器 'XXXXXX' 映射到本地用户 '(null)' 的远程用户 'XXXXXXX'.
解决办法：在本地服务器上执行： ALTER SERVICE MASTER KEY FORCE REGENERATE.
这个语句的功能是重新生成本地服务器的主密钥。
6:sqlserver恢复挂起

What is MySQL partitioning?Apr 27, 2025 am 12:23 AMMySQL partitioning improves performance and simplifies maintenance. 1) Divide large tables into small pieces by specific criteria (such as date ranges), 2) physically divide data into independent files, 3) MySQL can focus on related partitions when querying, 4) Query optimizer can skip unrelated partitions, 5) Choosing the right partition strategy and maintaining it regularly is key.

SQL injection can be prevented by using preprocessing statements. 2. Weak passwords can be avoided by forcibly using strong password strategies. 3. Improper permission configuration can be resolved through regular review and adjustment of user permissions. 4. Unupdated software can be patched by regularly checking and updating the MySQL version.
How can you identify slow queries in MySQL?Apr 26, 2025 am 12:15 AMIdentifying slow queries in MySQL can be achieved by enabling slow query logs and setting thresholds. 1. Enable slow query logs and set thresholds. 2. View and analyze slow query log files, and use tools such as mysqldumpslow or pt-query-digest for in-depth analysis. 3. Optimizing slow queries can be achieved through index optimization, query rewriting and avoiding the use of SELECT*.

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),
