所有mysql引擎之间的主要区别是什么？

I want to make a summary of the main differences between all the Mysql engines and of course the most populars also.

我想总结所有Mysql引擎之间的主要区别,当然也是最流行的。

And what criteria should I use to determine which engine to use?

They are very well described here:

他们在这里描述得非常好:

Use InnoDB, if you're in doubt. It is general-purpose and performs well.

如果您有疑问,请使用InnoDB。它是通用的并且表现良好。

You should take a look to the manual, like Lars and Phil said.

你应该看看手册,就像Lars和Phil说的那样。

Although, i could tell you in short, the differences between the primaries engines (MyISAM and innoDB) are in Transaction support, foraing key support, Locking level (MyISAM locks the entire table, innoDB has row level locking), and MVCC. There are too much many differences between them. I recommend you to take a look at: Pro MySQL Apress 2005.

虽然,我可以简单地告诉你,初级引擎(MyISAM和innoDB)之间的差异在于事务支持,搜索关键支持,锁定级别(MyISAM锁定整个表,innoDB具有行级锁定)和MVCC。它们之间存在太多差异。我建议你看看:Pro MySQL Apress 2005。
