Error with queries with oracle profile

Hi everybody.

I have a problem with oracle profile.

When I execute queries with criteria or hsql i dont have problems.

But when execute sql queries, like this:

SimpleJdbcTemplate jdbcTemplate =
new SimpleJdbcTemplate(SessionFactoryUtils.getDataSource(getSessionFactory()));
Table table = AnnotationUtils.findAnnotation(User.class, Table.class);
return jdbcTemplate.queryForObject(
"select password from " + table.name() + " where username=?", String.class, username);

The application throw the next exception: "Incorrect result size..." (more detail in the image).

WHat happend when use Oracle profile? With My SQL I dont have problems, but I must use Oracle.

Somebody can help me, please?

Thanks so much.
