Sorry, I should have added in the environment section that the stack trace is actually from Hibernate 2.1beta2 - although the code still fails on all the other mentioned versions of Hibernate!

Here is an overview of the issue:
---------------------------------------------------------------------
        Key: HB-297
    Summary: Named Parameters not recognized in 'order by' section of Query
       Type: Bug

     Status: Unassigned
   Priority: Major

    Project: Hibernate2
 Components: 
             core
   Versions:
             2.0.1
             2.0.2
             2.1 beta 1

Environment: java.version=1.4.2
os.name=Windows 2000
Mckoi DB 1.0.2

Description:

The following query using named parameters fails:

Query q=session.createQuery("from Location loc where (loc.lonLat.UnitX between :minX and :maxX) order by ABS( loc.lonLat.UnitX - :centX )");
q.setDouble("minX", x - r);
q.setDouble("maxX", x + r);
q.setDouble("centX", x);
Iterator locs = q.iterate(); // Fails with QueryException

The final bit with 'centX' causes the problem, as the following query, with the 'centX' removed, succeeds:

Query q=session.createQuery("from Location loc where (loc.lonLat.UnitX between :minX and :maxX) order by ABS( loc.lonLat.UnitX )");
q.setDouble("minX", x - r);
q.setDouble("maxX", x + r);
Iterator locs = q.iterate(); // Succeeds

Also, using JDBC-style un-named parameters works:

Query q=session.createQuery("from Location loc where (loc.lonLat.UnitX between ? and ?) order by ABS( loc.lonLat.UnitX - ? )");
q.setDouble(0, x - r);
q.setDouble(1, x + r);
q.setDouble(2, x);
Iterator locs = q.iterate(); // Succeeds

Both of these two succeeding queries bring back all the results I would expect, with the correct ordering - so none of the function-calls or presence of a parameter in the order-by clause should be illegal.

The full stack trace is:

net.sf.hibernate.QueryException: Named parameter does not appear in Query: centX [from com.thisbedisonfire.madgag.persistence.Location loc where (loc.lonLat.UnitX between :minX and :maxX) order by ABS( loc.lonLat.UnitX - :centX )]
	at net.sf.hibernate.hql.QueryTranslator.getNamedParameterLocs(QueryTranslator.java:437)
	at net.sf.hibernate.hql.QueryTranslator.bindNamedParameters(QueryTranslator.java:817)
	at net.sf.hibernate.loader.Loader.prepareQueryStatement(Loader.java:575)
	at net.sf.hibernate.hql.QueryTranslator.iterate(QueryTranslator.java:832)
	at net.sf.hibernate.impl.SessionImpl.iterate(SessionImpl.java:1436)
	at net.sf.hibernate.impl.QueryImpl.iterate(QueryImpl.java:29)
	at com.thisbedisonfire.madgag.Main.main(Main.java:105)

So, something's going wrong with binding of named parameters...

Hope you can help!
