《android进阶之光》——多线程编程（上） TAING要一直努力读书笔记
今天了解了下多线程编程，知识点如下：进程与线程：进程是什么？线程是什么？进程可以看作是程序的实体，是线程的容器，是受操作系统管理的基本运行单元，例如exe文件就是一个进程。线程是进程运行的一些子任务，是操作系统调度的最小单元，各线程拥有自己的计数器，堆栈，局部变量等，也可以访问线程间共享的内存。线程的状态有哪些？新创建，可运行，等待，超时等待，阻塞，终止怎么创建一个线程？-三种方法第一种，MyTr

有以下场景：用户下了一个订单，订单内的内容较多，且来自多表，首次下单的时候，内容可能会不全（部分内容不是必须，出现有些表根本就没有没有该订单的值）。在以后更改订单时，有些内容会更改，有些内容会新增。问题：如果在sql语句中执行update操作，在没有数据的表中会出错。如果在逻辑代码中先做查询，查询结果有做更新，没有做插入，这样会将代码复杂化。解决： mysql中提供了一个sql语
