Problem with HQL (Hibernate) Query using Netbeans 6.7.1

Question

Hi. I have a database which possesses only one table. This table is called "Login" and has two columns: "username" and "password". I have inserted two rows in it, so it is not empty.
Using HQL within Netbeans, I write the following query
FROM LoginThis results in HQL showing the correct result, the two rows added. But, let's say that I wanted only one of the two columns, like "username". I would do something like this:
SELECT log.username FROM Login AS logThis gives, the column with 2 rows (as expected), but in each row appears something weird. First of all, the column is not nada log.username, but "Bytes". The rows have for values something like "B@ebd...", and it's completely random, for when I ask for the result again, the "B@ebd..." can change to other word but it always begins with "B@".
I don't understand what I am doing wrong. I have tried many things, like using Upper Case, Lower Case, etc. It always work when selecting ALL the items from the table, but when asking for only a column, it goes crazy. Thanks for any help you can give

Answer 1

SELECT log.username FROM Login AS logThis is not HQL, it is plain SQL. This would be the HQL:
SELECT log.username FROM Login logThe result you are getting is a standard toString() representation of a class that does not have a toString() implementation itself. This would indicate that the value returned by the query is not a String object like you would expect. How this could happen, I cannot say. Not enough information.
