Hi,

I am having problems with rather simple Hibernate queries not returning the results I would expect when using query parameters:

Account account = (Account) entityManager
 .createQuery("SELECT c.account FROM Customer c WHERE c.salesperson.name = :salesname")
 .setParameter("salesname", salesGuyname).getSingleResult();

-> 0 results (NoResultException)

However, it works if I don't use query parameters and create the query string with concatenation:

Account account = (Account) entityManager
 .createQuery("SELECT c.account FROM Customer c WHERE c.salesperson.name = '" + salesGuyname + "'")
 .getSingleResult();

-> 1 result (the one I'm expecting)

I'm using JBoss 4.2.2 with MySQL 4.1. Does anyone have an idea where this could come from?

Thanks,
Georges
