当前非安装版是从MySQL.com下载来的v5.1.40;下载下来的是一个ZIP压缩包,解压到C:\MySQL5.1.40目录,接下来,设置系统环境变量,好在CMD命令行下使用MySQL。
环境变量设置:单击桌面我的电脑右键属性->高级->环境变量->双击Path项,添加C:\MySQL5.1.40\bin目录,如果要使用SDK开发,则要添加Lib和include目录到对应的Lib和include环境变量中;环境变量设好,在开始菜单->运行->CMD,执行MySQLD,或是直接切换到C:\MySQL5.1.40\bin目录双击运行MySQLD.exe服务程序,也可以服务的形式运行: 注意mysql安装目录不要有中文或空格,在SDK开发中,如QT会有意想不到的问题;
安装服务 mysqld -install
启动服务 net start mysql
停止服务 net stop mysql
删除服务 mysqld -remove
再打开一个CMD窗口,执行MySQL -h localhost回车,就可以看到
{
Welcome to the MySQL monitor. Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
}
表示成功连接到MySQL了数据库了,接下来,可以查看数据库,

Optimizing 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.

Mastering 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.

Best 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),
