我希望总结一下所有Mysql引擎之间的主要区别,当然也包括最受欢迎的引擎。
那么我应该使用什么标准来确定使用哪个引擎呢?

这里对它们进行了很好的描述:
http://dev.mysql.com/doc/refman/5.0/en/storage-engines.html
如果您不确定,使用InnoDB。它是通用型的,并且性能良好。
正如Lars D所说,这里有非常好的描述:

以上数据来自上面提供的链接,可能会对您有所帮助...

你应该像Lars和Phil说的那样查看手册。
虽然我可以简单地告诉你,主要引擎(MyISAM和innoDB)之间的区别在于事务支持、外键支持、锁定级别(MyISAM锁定整个表,innoDB具有行级锁定)和MVCC。它们之间有太多的不同。我建议你看一下:Pro MySQL Apress 2005。
