本来是想把解决PLSQL中文乱码问题，可问题是一个接着一个的出现，想看看中文乱码问题解决没有，结果查询表时又弹出这样一个错误。
拿着有道查了一下，说是动态性能表没有权利被访问。上网查了一下相关的问题，才知道原来PLSQL在用户运行过程中，要收集用户统计信息，但是由于我们现在登录的用户没有权限访问v$session,v$sesstat和v$statname视图，所以不能收集当前用户的统计信息，和PLSQL工具中配置的Automatic Statistics相冲突，所以会出现上面的提示信息。
所以我的解决方案是彻底禁掉PLSQL的统计功能。选择Tools——Preferences，然后找到Options，把Automatic Statistics选项前面的小勾去掉，点击保存，退出。
这个是最简单的办法，除此之外，又查到两个方法，其中一个比较狗血，就是把上面问题提示框中的“Don't show this message again”选项勾选，让下次不要再出现这个提示框，这个方法有点让人不能接受啊。
另外一个方法就是给访问用户授权，让用户有权限访问这三个视图。第三种方法给大家推荐一个博客，我觉得这个博客中介绍的非常详细，在这里我就不再赘述了。博客地址：http://blog.itpub.net/519536/viewspace-614671/
无论哪种方法解决了问题，最终的目的都是为了方便大家学习。PLSQL让我很头疼，但是也让我接触了很多它的意外状况，让我能够对它认识更深刻，了解的更深入。

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),
