业界担忧MySQL命悬一线_MySQL
甲骨文是商用数据库巨头,而Sun旗下有一款全球知名的开源数据库MySQL,MySQL未来命运如何,是否会被甲骨文“消灭”或者转让,这引发了业界的担忧.
MySQL是开源WEB开发套件LAMP中的数据库组件,被用于全球数万网站的数据库后台.最近,该开源数据库进入企业级市场,获得成功,由 此,MySQL也成为甲骨文“拳头产品”Oracle Database 11g的对手.业界专家分析说,最理想的一种情况是,甲骨文针对两种数据库进行不同的市场定位,同时销售两款产品.实际上,MySQL还可以从甲骨文的数 据库技术中吸取长处.
不过让人担心的是,对于甲骨文来说,他们一直希望自己的企业客户使用更加昂贵的数据库产品.这样,继续维护一款进入企业级市场的开源数据库已经不符合甲骨文的利益.
在一封谈及收购Sun的信件中,甲骨文总裁查尔斯·菲利普斯谈到了公司拥有Java和Soloris操作系统的好处,但对于MySQL数据库则没有提到一个字.这显然不是MySQL客户希望看到的.
实际上,除了Oracle Database 11g,甲骨文拥有开源数据库产品,比如Berkeley DB以及InnoDB,不过影响力要远小于MySQL.
业界媒体纷纷指出,未来甲骨文如何处置拥有海量开源用户的MySQL,这还需要拭目以待.

How to recover data after SQL deletes rows
Apr 09, 2025 pm 12:21 PM
Recovering deleted rows directly from the database is usually impossible unless there is a backup or transaction rollback mechanism. Key point: Transaction rollback: Execute ROLLBACK before the transaction is committed to recover data. Backup: Regular backup of the database can be used to quickly restore data. Database snapshot: You can create a read-only copy of the database and restore the data after the data is deleted accidentally. Use DELETE statement with caution: Check the conditions carefully to avoid accidentally deleting data. Use the WHERE clause: explicitly specify the data to be deleted. Use the test environment: Test before performing a DELETE operation.

Redis uses a single threaded architecture to provide high performance, simplicity, and consistency. It utilizes I/O multiplexing, event loops, non-blocking I/O, and shared memory to improve concurrency, but with limitations of concurrency limitations, single point of failure, and unsuitable for write-intensive workloads.
