------------------------------------

                 Key: HHH-6253
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6253
             Project: Hibernate Core
          Issue Type: Bug
          Components: core, query-hql
    Affects Versions: 3.6.4, 3.6.3
            Reporter: Sebastian H.


Using the following SQL Dialect

public class ServiceAppMySQL5InnoDBDialect extends MySQL5InnoDBDialect {

	public ServiceAppMySQL5InnoDBDialect() {
		super();
		registerFunction("bitwise_and", new SQLFunctionTemplate(StandardBasicTypes.INTEGER, "(?1 & ?2)"));
		registerFunction("hasflags", new SQLFunctionTemplate(StandardBasicTypes.BOOLEAN, "?1 & ?2 = ?2"));
	}
}

and HQL query

Query q = em
	.createQuery(
		"SELECT o FROM "
			+ entityClass.getName()
			+ " o WHERE hasflags(o.status, :status)")
	.setParameter("email", username)
	.setParameter("status", status.getBitmask());

results in the following exception
