不错，就是文档太恶心鸟

还是greenDao吧。

相比greenDao用的应该比较多，稳定，性能好，但是太麻烦，学习成本高，还要code generate，没时间研究

Whenever your schema changes you need to increment the database version number, either through Configuration or AA_DB_VERSION meta-data. If new classes are added, ActiveAndroid will automatically add them to the database. If you want to change something in an existing table however (e.g. add or delete a column), this is done using sql-scripts named <NewVersion>.sql, where NewVersion is the AA_DB_VERSION, inassets/migrations.

ActiveAndroid will execute a script if its filename is greater than the old database-version and smaller or equal to the new version.

Let’s assume you added a column color to the Items table. You now need to increase AA_DB_VERSION to 2 and provide a script 2.sql.

ALTER TABLE Items ADD COLUMN color INTEGER;
