MySQL daemon don't lock tables or records if you don't require this.

Can I ask if this is in fact accurate? As I understand it, MySQL does a fairly good job of locking the tables, that's part of the performance problem of MyISAM vs. InnoDB table types with many updates running. And with InnoDB, you get a Repeatable Read isolation level by default which 'feels like' getting a read lock.

What did you mean that it doesn't lock tables? SQL
