我们大家都知道MySQL数据库主要有2种类型,一是数据表格式(传统),二是支持事务处理的数据表格式,以下我们就像大家介绍一下关于MySQL(和PHP搭配之最佳组合)事务处理数据库的安装MySQL及使用方法。
你先要去下载一下MySQL(和PHP搭配之最佳组合) max版的安装MySQL程序,下载地址:www.MySQL(和PHP搭配之最佳组合).com
按常规的方法进行安装
安装MySQL完成后,启动MySQL(和PHP搭配之最佳组合)binWinMySQL(和PHP搭配之最佳组合)admin
再退出
运行
MySQL(和PHP搭配之最佳组合)binmydqld-nt --remove
MySQL(和PHP搭配之最佳组合)binMySQL(和PHP搭配之最佳组合)d-max-nt --install
以上二行是去掉不支持事务处理的MySQL(和PHP搭配之最佳组合)服务,改成支持MySQL(和PHP搭配之最佳组合)事务处理的服务
然后在c:下建一个ibdata目录及iblogs目录,当然名字可以不一样,记住这二个名字及盘符,以后要用到,你也可以不建在C盘,然后,打开c:winnt或c:windows目录下的my.ini,在最后添加:以下内容为程序代码:
<ol class="dp-xml"> <li class="alt"><span><span>innodb_data_file_path = ibdata1:2000M;ibdata2:2000M </span></span></li> <li><span>innodb_data_home_dir = c:ibdata </span></li> <li class="alt"> <span>set-variable = </span><span class="attribute">innodb_mirrored_log_groups</span><span>=</span><span class="attribute-value">1</span><span> </span> </li> <li><span>innodb_log_group_home_dir = c:iblogs </span></li> <li class="alt"> <span>set-variable = </span><span class="attribute">innodb_log_files_in_group</span><span>=</span><span class="attribute-value">3</span><span> </span> </li> <li> <span>set-variable = </span><span class="attribute">innodb_log_file_size</span><span>=</span><span class="attribute-value">30M</span><span> </span> </li> <li class="alt"> <span>set-variable = </span><span class="attribute">innodb_log_buffer_size</span><span>=</span><span class="attribute-value">8M</span><span> </span> </li> <li> <span class="attribute">innodb_flush_log_at_trx_commit</span><span>=</span><span class="attribute-value">1</span><span> </span> </li> <li class="alt"><span>innodb_log_arch_dir = c:iblogs </span></li> <li> <span class="attribute">innodb_log_archive</span><span>=</span><span class="attribute-value">0</span><span> </span> </li> <li class="alt"> <span>set-variable = </span><span class="attribute">innodb_buffer_pool_size</span><span>=</span><span class="attribute-value">80M</span><span> </span> </li> <li> <span>set-variable = </span><span class="attribute">innodb_additional_mem_pool_size</span><span>=</span><span class="attribute-value">10M</span><span> </span> </li> <li class="alt"> <span>set-variable = </span><span class="attribute">innodb_file_io_threads</span><span>=</span><span class="attribute-value">4</span><span> </span> </li> <li> <span>set-variable = </span><span class="attribute">innodb_lock_wait_timeout</span><span>=</span><span class="attribute-value">50</span><span> </span> </li> </ol>
其中
<ol class="dp-xml"><li class="alt"><span><span>innodb_data_file_path = ibdata1:2000M;ibdata2:2000M </span></span></li></ol>
这一行中的2000M可以自己改成200m,看你盘的容量大小,MySQL(和PHP搭配之最佳组合)推荐10G及以上的硬盘空间最好用这样的设置;
以下这一行
<ol class="dp-xml"><li class="alt"><span><span>innodb_data_home_dir = c:ibdata </span></span></li></ol>
也可以改成你自己起的目录,主要是看你自己在刚才建的目录在哪里啦
按照以上的方法,你已经安装MySQL好了MySQL(和PHP搭配之最佳组合)的事务数据库,不过你要是按照MySQL(和PHP搭配之最佳组合)手册上的方法安装,把上面的一段配制放到my.cnf是去的话,可是会出错哦
好了,现在让我们试试看是不是安装完成了,启动apache(Unix平台最流行的WEB服务器平台),或iis,在服务里启动MySQL(和PHP搭配之最佳组合)的服务,打开phpmyadmin,输入:SHOW variables like "have_%"
你要是看到下面的结果,那说明你安装MySQL成功了
以下内容为程序代码
<ol class="dp-xml"> <li class="alt"><span><span>Variable_nameValue </span></span></li> <li><span>have_bdbYES </span></li> <li class="alt"><span>have_innodb YES </span></li> <li><span>have_isam YES </span></li> <li class="alt"><span>have_raid NO </span></li> <li><span>have_symlink YES </span></li> <li class="alt"><span>have_openssl NO </span></li> <li><span>have_query_cacheYES </span></li> <li class="alt"><span> </span></li> </ol>
注:MySQL(和PHP搭配之最佳组合)的事务处理方法的使用同其它数据库语法相似,在这里我就不多说了,另外,MySQL(和PHP搭配之最佳组合)将在4.3中实现外键及子查询,简单的外键已经在4.0中都已经实现了,只是不怎么方便,相信以后会做得更好些。
关于事务表的使用,我已经成功地在我的网上订单管理系统中实现,效果还不错,只是还没有经过大数据量的实践
以上文章是本人自己根据实践写出来的,如要转载,请注明出处及作者,也欢迎大家和我一起讨论关于MySQL(和PHP搭配之最佳组合)事务表的一些问题
以上的相关内容就是对安装MySQL事务数据库(InnoDB)的介绍,望你能有所收获。

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA
