Access
access 只能在 windows 下使用这一致命的特性让我深恶痛绝,痛下决心要把 access 转换到 mysql,但是从网上找了很多文章,都没有直接转换的东西。听说可以利用odbc转,就尝试了一下。
先安装好mysql,myodbc,建一个mysql的空数据库,在odbc管理中加上这个数据库,指定名称。
用access2000打开数据库,然后选导出,选odbc,选机器数据源,选中自己刚才建立好的mysql odbc 数据源,确定后导出。
一次只能倒一个表。
。。。。。。。。。。
终于完了,现在成功了吗?
把程序中的数据源改到刚倒好的mysql odbc上,发现到处都是错误,原来mysql对表的大小写有区分,改了程序后,运行感觉不错,速度也可以。
不对,怎么又错了,这个ID怎么是空的???
原来这个倒入的数据库不支持自动递增的功能。
继续到mysql的目录,bin下运行 mysqldump 倒出所有的结构和数据到一个文件 my.sql然后编辑 my.sql,修改所有的 CREATE TABLE 语句,
ID int not null auto_increment, primary key (ID), 这样ID就相当于access中的自动编号数据类型了,在 mysql/bin 下运行mysql,drop掉原来的数据库,再source一下刚才修改过的这个my.sql所有数据恢复进去,好,这下一切搞定,程序比往常要快了许多,尤其是论坛部分。
注:此次操作均在 windows 2000 下进行。

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.

When selecting MySQL's BLOB and TEXT data types, BLOB is suitable for storing binary data, and TEXT is suitable for storing text data. 1) BLOB is suitable for binary data such as pictures and audio, 2) TEXT is suitable for text data such as articles and comments. When choosing, data properties and performance optimization must be considered.

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),
