将Session值储存于SQL Server中
一般情况下，我们喜欢使用Session储存我们的变量。Asp.Net提供了下面一些方法储存Session的值：InProc
State Server
SQL Server
“InProc”表示我们使用传统ASP一样的方法储存Session的值，而且“State Server”则表示使用另外一台主机来储存Session的值。当然我们也能使用SQL Server储存值，我们这篇文章就专门用于讲解这种方法。
运行InstallSqlState.sql文件
首先需要在WinntMicrosoft.Net中找到InstallSqlState.sql文件，然后在SQL Server 中执行它。在我的机器中，它存在于E:WINNTMicrosoft.NETFrameworkv1.0.2914目录中。这个文件是微软自己提供的，里面有很全的SQL语句，大家放心使用。下图就是生成的数据表。
修改你的web.config文件，指定Session的mode为SQL Server
将web.config的sessionState部分改成：
WIN2000;userid=
sa;password=" cookieless= "false"timeout=
"20" />
创建Asp.Net Web Forms
下面就建立一个测试的ASP.net程序，使用Session程序这里就不用多说了，下面是我的程序的截图。这个程序只是简单的储存一个字符串数据于Session中，然后再显示这个数据在Label控件中。
现在所有的Session变量都储存在数据表中，而不是内存中了。你可打开ASPStateTempSessions表来查看这些Session数据了。
删除这些数据库和表
如果你不喜欢这个数据储存方式，看得实在是不爽，那么你可以把这些表和数据库完全删除掉。这个也不要担心这种删除会影响数据库（因为害怕误删除一些数据），因为微软同样也得供给你们一个删除SQL 文件，名叫UnintallSQLState.sql。它与IntallSQLState.sql一样放在.Net的Config目录中。

MySQL BLOB: how to optimize BLOBs requestsMay 13, 2025 am 12:03 AMOptimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.
Adding Users to MySQL: The Complete TutorialMay 12, 2025 am 12:14 AMMastering the method of adding MySQL users is crucial for database administrators and developers because it ensures the security and access control of the database. 1) Create a new user using the CREATEUSER command, 2) Assign permissions through the GRANT command, 3) Use FLUSHPRIVILEGES to ensure permissions take effect, 4) Regularly audit and clean user accounts to maintain performance and security.

MySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AMBest practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.

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),
