安装
linux 下的ODBC 有两种：unixODBC 和iodbc ，由于wxGTK 提供的是对iodbc 的支持，因此在安装wxGTK 前需要先安装iodbc 。在后面安装freetds 时，依据环境和依赖关系可能会将unixODBC 也装上，iodbc 和unixODBC 修改的ODBC 配置文件都是/etc/odbc.ini 和/etc/odbcinst.ini ，这两个都是ODBC 驱动的管理器，没有冲突问题，但如果要使用wxODBC 进行ODBC 的开发，iodbc 是必须要安装的。
安装 iodbc
如果有yum 源中包括libiodbc ，可直接使用yum install libiodbc* 或在yumex 中搜索iodbc 的包进行安装，否则需要到网上下载相关的rpm 包进行安装。
下载libiodbc-3.52.6-1.i386.rpm
下载libiodbc-devel-3.52.6-1.i386.rpm
下载 libiodbc-admin-3.52.6-1.i386.rpm
下载libiodbc-3.52.6-1.src.rpm
rpm -ivh libiodbc-3.52.6-1.i386.rpm
rpm -ivh libiodbc-devel-3.52.6-1.i386.rpm
rpm -ivh libiodbc-admin-3.52.6-1.i386.rpm
rpm -ivh libiodbc-3.52.6-1.src.rpm
安装wxGTK
./configure --with-odbc --enable-monolithic --enable-xrc --enable-unicode
make
make install
安装 codeblocks
cp /usr/local/share/aclocal/wxwin.m4 /usr/share/aclocal/wxwine.m4
./bootstrap ( 可能需执行aclocal)
./configure --with-contrib-plugins=all
make
makeinstall
连接 SQL Server
安装 freetds
yum install freetds ＊
( 或安装yum yumex 后，执行yumex ，到所有包里搜索freetds, 安装找到的包，有三个，另两个是develop 包和doc 包)
配置 ODBC 驱动
/usr/bin/iodbcadm-gtk
到ODBC Drivers 中点ADD a driver
在description of driver 中填入对驱动连接数据库的描述如MSSQL 或SQL server
在driver file name 中填入/usr/lib/libtdsodbc.so( 具体路径可能有因版本有差异，可搜索libtdsodbc.so 找到具体的路径)
在Setup file name 中填入/usr/lib/libtds.so( 具体路径可能有差异)
点击OK 保存ODBC 驱动的设置
配置 DSN
在 iodbcadm-gtk 切换到system DSN
点击Add, 在出现的窗口中选择要使用的配置好的驱动后点击OK
Data Source Name (DSN) 中填入新建的DSN 源的名称
新建如下Keyword, 并填入值
Keyword Value
Database 使用的数据库
Port 使用的端口号(SQL Server 为1433)
Server 服务器( 可使用IP 地址)
TDS_Version 8.0
Trace No
点OK 保存DSN
点击Test 测试该数据源，弹出窗中填入用户名密码后点OK 看测试情况
点OK 退出iodbcadm-gtk
可使用
isql -v DSN 名 用户名密码
连接DSN
MySQL
安装驱动
用yumex 检查mysql-connector-odbc 包有没有安装，如果没有，使用yum install mysql-connector-odbc 进行安装
配置 ODBC 驱动
在iodbcadm-gtk 中切换到ODBC Drivers ，点击ADD a driver
在description of driver 中填入对驱动连接数据库的描述如MySQL
在driver file name 中填入/usr/lib/libmyodbc3.so( 名称按mysql 的驱动版本可能不同，，如可能会是libmyodbc.so )
在Setup file name 中填入/usr/lib/libodbcmyS.so 具体路径可能有差异)
点击OK 保存ODBC 驱动的设置
配置 DSN
在 iodbcadm-gtk 切换到system DSN
点击Add, 在出现的窗口中选择要使用的配置好的驱动后点击OK
Data Source Name (DSN) 中填入新建的DSN 源的名称
新建如下Keyword, 并填入值
Keyword Value
Database 使用的数据库
Server 服务器( 可使用IP 地址)
user 用户名
password 密码
点OK 保存DSN
然后可点Test 测试或在命令行下用
isql -v DSN 名 用户名密码

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),
