怎样在vc、delphi、vb等程序中使用mysql呢(mysql odbc驱动程序的使用)

我们经常会遇到这样问题,怎样在非web程序或asp程序中使用mysql数据库呢?对于这个问题有两个解决方案:

1.使用mysql提供的api函数库。
很多有名的mysql客户端工具就是这样实现的,大名鼎鼎的winmysql工具就是这样的。这在大部分的开发工具中都可以实现。
比如vc,bcb,delphi,vb等,只要能调用第三方的api就能实现。但对程序员的要求很高,而且要熟悉一套mysql的api函数集,这不是对每个人都很轻松的事。而且这种方法不能用于asp等程序,因为它不支持com对象。

2。第二种是使用myodbc驱动程序。
你可以到下载myodbc驱动程序,然后照着下面的做就可以了。

第一种选择是下载完全安装包,这种包很大,但对于我们来说有用的只有myodbc.dll这个文件,却要下载这么大的文件,不太合适。当然,,如果你很菜的话,我建议你选择这种方式,这样容易些,但不符合cfans的作风,是吧。

第二种是直接下载myodbc.dll文件,只有几百k,但不太容易使用,本人经过很久摸索才找到使用它的方法。

首先你将包解开,将myodbc.dll 文件放到windowssystem 或 winntsystem32目录下,这取决于你的系统是win9x还是winnt(win2k),你应该知道吧。

然后打开一纯文本编辑器,如editplus,notpad之类,(取决于你的喜好)将下面一段话保存为一文件,扩展名为.reg,知道了吧,这是注册表文件,不要搞

错呀(不包括下面的一长串等号)

如果你用的是win2k请将第一行换成

Windows Registry Editor Version 5.00

MySQL: String Data Types and CollationsMySQL: String Data Types and CollationsMay 09, 2025 am 12:08 AM

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

MySQL: What length should I use for VARCHARs?MySQL: What length should I use for VARCHARs?May 09, 2025 am 12:06 AM

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.

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),
