只能在子线程中执行？我咋没听说过这个说法，一般是单纯的非耗时数据库操作，我都是在主线程操作的，除了占用了资源之外，并未报错过，我只知道，数据库不能做并发写入操作，还真不知道不能在主线程操作。[/quote]
[/quote]
我还真没注意过这个，我做的全局数据库管理，专门给数据库的创建和更新预留了线程，但是数据库的读取和写入都是同步操作，从不用子线程异步操作

错误日志发的不对，再看看教程。
idea的黄色提示或者红线提示要仔细看看，如你的单词AUTOTNCREMENT，这都能打错

Android操作数据库需要在子线程中执行。你直接在主线程中操作数据库当然报错误了。修改一下数据库操作就可以了。
