第二部分 iODBC
一.iODBC简介
iODBC是个免费的MySQL库ODBC接口.因为短小精悍,广为流传.
二.iODBC安装
1.从 ftp://166.111.68.178/linux/database下载
iodbc-2.12-3.src.rpm
!!!(不要下载iodbc-2.12-3.i386.rpm ,该包有问题,自带的ODBC
工具monitor,odbctool可以执行,但是链接iodbc.so自己写
的程序链接出错,如果只是用它的工具当然可以,二次开发
就不行了.)
2.用 rpm -ivh iodbc-2.12-3.src.rpm 解开 ,生成文件
/usr/src/redhat/SOURCES/iodbc-2.50.11.tgz ,找个目录
解开 tar zxvf /usr/src/redhat/SOURCES/iodbc-2.50.11.tgz
建议放在 /usr/local 下,会建立目录 iodbc.
3.要想iODBC-src正常编译,需要修改很多文件,包括
iodbc/SAMPLES/Makefile
iodbc/myodbc-2.50.11/config.h
iodbc/myodbc-2.50.11/m_string.h
iodbc/myodbc-2.50.11/connect.c
为方便使用,我将改动过的iODBC打了一个包,叫做
iodbc-2.50.11-lg.tgz, :-)权充一回自由软件者.因为上网不便,
暂时还没有放上来,抱歉. //sorry
4.安装后iODBC在/usr/lib/iodbc 之下.配置文件为iodbc.ini .
三.iODBC配制
其实 iodbc.ini 文件已经讲地很详细了,我这里再多说什么也很多余,
那我就讲些它没说的.
iodbc.ini中有一项是设置 SERVER 的,就是 MySQL 数据库所在的
机器名,在iodbc-2.12-3.src.rpm和iodbc-2.12-3.i386.rpm中都是
摆设:p,网上我看到的好象都是酱紫的.后来我改动了一些iODBC中
的一些ODBC驱动程序,(//smile,真是要为开放源代码欢呼了!!!).
~~~~~~~~~~~~~~~~~~
让它访问远端的MySQL服务器.细节暂时保密,其实你可以看代码的说.
现在好了,就是在iodbc.ini文件里设置[identify] 和 DSN 必须是
相同的,DB才是远端实际的数据库名.至于本地机就不用设DB了,
推荐的远端DSN命名方法为 databasename.hostname ,即:
本地: [identify] //随意.hehe
DSN = databasename
SERVER = localhost
...
远端: [databasename.hostname]
DSN = databasename.hostname
SERVER = hostname
...
很简单吧. :-)

PHP's big data structure processing skills
May 08, 2024 am 10:24 AM
Big data structure processing skills: Chunking: Break down the data set and process it in chunks to reduce memory consumption. Generator: Generate data items one by one without loading the entire data set, suitable for unlimited data sets. Streaming: Read files or query results line by line, suitable for large files or remote data. External storage: For very large data sets, store the data in a database or NoSQL.
How to optimize MySQL query performance in PHP?
Jun 03, 2024 pm 08:11 PM
MySQL query performance can be optimized by building indexes that reduce lookup time from linear complexity to logarithmic complexity. Use PreparedStatements to prevent SQL injection and improve query performance. Limit query results and reduce the amount of data processed by the server. Optimize join queries, including using appropriate join types, creating indexes, and considering using subqueries. Analyze queries to identify bottlenecks; use caching to reduce database load; optimize PHP code to minimize overhead.

The difference between oracle database and mysql
May 10, 2024 am 01:54 AM
Oracle database and MySQL are both databases based on the relational model, but Oracle is superior in terms of compatibility, scalability, data types and security; while MySQL focuses on speed and flexibility and is more suitable for small to medium-sized data sets. . ① Oracle provides a wide range of data types, ② provides advanced security features, ③ is suitable for enterprise-level applications; ① MySQL supports NoSQL data types, ② has fewer security measures, and ③ is suitable for small to medium-sized applications.
