* 事务

//事务能够用来管理insert 、update 、delete语句。 一般事务必须满足的4个条件：原子性（Atomicity，或称不可分割性）、一致性（Consistency）、隔离性（Isolation，又称独立性）、持久性（Durability）。 事务简单来说就是做一件事要么成功，要么全部完成，要么全部不完成。事务在执行过程中发生错误，会被回滚（Rollback）到事务开始前的状态，就像这个事务从来没有执行过一样。

//###MySQL事务处理用 BEGIN, ROLLBACK, COMMIT来实现 1、BEGIN 开始一个事务 2、ROLLBACK 事务回滚 3、COMMIT 事务确认
