Hibernate Query Exception
Question
I've got a hibernate query I'm trying to get working but keep getting an exception with a not so helpful stack trace. I'm including the code, the stack trace, and hibernate chatter before the exception is thrown. If you need me to include the entity classes for MessageTarget and GrpExclusion let me know in comments and I'll add them.
public List<MessageTarget> findMessageTargets(int age, String gender, String businessCode, String groupId, String systemCode) {
Session session = getHibernateTemplate().getSessionFactory().openSession();
List<MessageTarget> results = new ArrayList<MessageTarget>();
try {
String hSql = "from MessageTarget mt where " +
"not exists (select GrpExclusion where grp_no = ?) and " +
"(trgt_gndr_cd = 'A' or trgt_gndr_cd = ?) and " +
"sys_src_cd = ? and " +
"bampi_busn_sgmnt_cd = ? and " +
"trgt_low_age <= ? and " +
"trgt_high_age >= ? and " +
"(effectiveDate is null or effectiveDate <= ?) and " +
"(termDate is null or termDate >= ?)";
results = session.createQuery(hSql)
.setParameter(0, groupId)
.setParameter(1, gender)
.setParameter(2, systemCode)
.setParameter(3, businessCode)
.setParameter(4, age)
.setParameter(5, age)
.setParameter(6, new Date())
.setParameter(7, new Date())
.list();
} catch (Exception e) {
System.err.println(e.getMessage());
e.printStackTrace();
} finally {
session.close();
}
return results;
}
Here's the stacktrace.

You are not writing your HQL properly. I would recommend reading the HQL chapter from the documentation.
There are a few things I see wrong off with your query:
- Your subselect is not a valid HQL query. Something like (from GroupExclusion ge where groupNumber = ?) would probably be closer to what you want.
- Column names should match their Java getter names and not the database column names.
You should close your HibernateSession in a finally block:
Session session = getHibernateTemplate().getSessionFactory().openSession(); try { ... } finally { session.close(); }
