数据库引擎被甲骨文操控 MySQL开始另谋后台_MySQL
甲骨文
作者:令狐达【eNet硅谷动力消息】据国外媒体报道,一枝独秀的开源数据库MySQL上月推出了最新的5.0版,与此同时,全球数据库软件巨头甲骨文宣布收购开源数据库厂商Innobase。于是,MySQL和甲骨文这两个有着天壤之别的数据库公司扯上了关系——MySQL的数据库引擎正是Innobase的产品。数据库业界非常关注要和开源数据库竞争的甲骨文是否会采取什么"不 道义"动作"切断"MySQL的后路。11月22日,MySQL先下手为强,该公司高层表示,正在考虑向用户提供另外一个不同于Innobase的数据库引擎。
MySQL负责EMEA(欧洲、中东、非洲)市场的副总裁理查德·马森22日表示:"很显然,由于甲骨文收购了Innobase公司,我们正在考虑以某种方式取代Innobase的数据库引擎。" 马森说目前还不能公开详细的计划,但估计很快就会出台。
MySQL数据库一直采用芬兰开源数据库厂商Innobase的数据库引擎。该软件组件被认为是在在线事务处理应用中最优秀的数据库引擎产品。
上月,在宣布收购Innobase时,甲骨文公司表示将会继续开发Innobase旗下的技术。据悉,Innobase数据库引擎目前通过一个长期协议和MySQL打包发行,而这个协议明年将需要续签。
22日在伦敦召开的MySQL北欧客户会议上,该公司的联合创始人David Axmark所遭遇的第一个问题就是,甲骨文收购Innobase将给给MySQL带来什么影响。Axmark回答说,数据库引擎是"可插拔"的,言下之意是Innobase数据库引擎可以被替换。不过,Axmark指出,MySQL在根据开源的GPL许可协议使用Innobase的软件,因此不存在其代码不能使用的问题。
据业界猜测,MySQL可能会根据现有的Innobase产品开发一个新版的数据库引擎,或是转向其他开源的数据库引擎。
数据库专家表示,即使MySQL明年无法和Innobase续签协议,该数据库仍然可以使用现有的殷勤代码。不过,如果甲骨文保留一些算法和文件结构等底层技术的专利,则局面会比较复杂,MySQL也只能转向其他引擎。
据MySQL公司称,其开源数据库的下载已经超过了100万份。此外,MySQL公司已经和戴尔、惠普和Novell等公司签署了全球发行协议,也可按每台服务器收取一定年费的方式提供后续技术支持。

Backing up and restoring a MySQL database in PHP can be achieved by following these steps: Back up the database: Use the mysqldump command to dump the database into a SQL file. Restore database: Use the mysql command to restore the database from SQL files.

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.

How to insert data into MySQL table? Connect to the database: Use mysqli to establish a connection to the database. Prepare the SQL query: Write an INSERT statement to specify the columns and values to be inserted. Execute query: Use the query() method to execute the insertion query. If successful, a confirmation message will be output.

Creating a MySQL table using PHP requires the following steps: Connect to the database. Create the database if it does not exist. Select a database. Create table. Execute the query. Close the connection.

To use MySQL stored procedures in PHP: Use PDO or the MySQLi extension to connect to a MySQL database. Prepare the statement to call the stored procedure. Execute the stored procedure. Process the result set (if the stored procedure returns results). Close the database connection.

One of the major changes introduced in MySQL 8.4 (the latest LTS release as of 2024) is that the "MySQL Native Password" plugin is no longer enabled by default. Further, MySQL 9.0 removes this plugin completely. This change affects PHP and other app

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

How to use MySQLi to establish a database connection in PHP: Include MySQLi extension (require_once) Create connection function (functionconnect_to_db) Call connection function ($conn=connect_to_db()) Execute query ($result=$conn->query()) Close connection ( $conn->close())
