Sugar ORM on Android: updating a saved object in SQLite

Question

I am new to application development using SQLite and Sugar ORM on Android and tried to read the Sugar ORM documentation but found nothing how to update a saved object in SQLite. Can I save an object after changing its properties? sort of:

Customer myCustomer = (Customer.find(Customer.class, "id = ?", id)).get(0);
myCustomer.setName("new name");
myCustomer.setAddress("new Address");
myCustomer.save(); // is this okay for updating the object?

the save () method will not create another new object, leaving the old record intact, right?

Answer 1

He will renew your essence. Sugar ORM overwrites an existing name, such as Name, and updates it with the "new name" after calling save ().

Answer 2

Your code should update the line without problems.

- Update Entity:

Book book = Book.findById(Book.class, 1);
book.title = "updated title here"; // modify the values
book.edition = "3rd edition";
book.save(); // updates the previous entry with new values.
