本篇文章為大家展示了MySQL中的過時(shí)表述分析,內(nèi)容簡(jiǎn)明扼要并且容易理解,絕對(duì)能使你眼前一亮,通過這篇文章的詳細(xì)介紹希望你能有所收獲。
作為MySQL的默認(rèn)存儲(chǔ)引擎,在性能和可用特征之間,MyISAM提供一種良好的平衡,
這些特征包括全文檢索,壓縮,空間函數(shù)。MyISAM不支持事務(wù)和行級(jí)鎖。
這是因?yàn)閷憰荕ySQL的版本還沒有到5.1

InnoDB
is a general-purpose storage engine that balances high reliability and high performance. Starting from MySQL 5.5.5, the default storage engine for new tables is InnoDB
rather than MyISAM
. Unless you have configured a different default storage engine, issuing a CREATE TABLE
statement without an ENGINE=
clause creates an InnoDB
table. Given this change of default behavior, MySQL 5.5 might be a logical point to evaluate whether tables that use MyISAM
could benefit from switching to InnoDB
.
在5.5.5之后,InnoDB已經(jīng)成為了MySQL的默認(rèn)存儲(chǔ)引擎
InnoDB
includes all the features that were part of the InnoDB Plugin for MySQL 5.1, plus new features specific to MySQL 5.5 and higher.
