You could use the GreenDao QueryBuilder to do SELECTs. But this would be overkill for your example.

In your case, since you are simply dumping out the entire table, you can just use the loadAll() method of your entity's Dao class. This illustrates why using DAO is so powerful.

For example, if your entity is named "Seguimento", you can call: daoSession.getSeguimentoDao().loadAll(), which will return a List<Seguimento>.
