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 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4111128#...
