I want to know how to perform the CRUD operation in GreenDAO?

Question

I am very new to GreenDAO, I don't know how to do CRUD operations in GreenDAO. I did some CRUD operation to retrieve the username and password that was totally making me confusion.Any one help to do CRUD operation in GreenDAO.

Code:

loginDao=DataProvider.getLoginDao(context);
QueryBuilder PasswordQuery = loginDao.queryBuilder().where(LoginDao.Properties.Password.eq("@user123"));

output Logcat:

   name: de.greenrobot.dao.query.QueryBuilder@68ca4d0

(Like this I got error when i retrieved the username and password)

Anyone resolve my problem to make me understand of those issue.

Thanks in Advance.
