Having a frustrating problem with Hibernate 3.6.9. MS SQL Server 2008. Note the exception and the odd column index reference.
The HQL Query itself:
Select r from DataStoreReference r join fetch r.container c where r.hash=:hash and r.state=0
The stack trace:

Now, I’d understand this from logic (and from googling) if the following were not true
a) every instantiation of DataStoreReference is shortly followed by a setUsage of System.currentTimeMillis)
b) the item is marked not-null in the mapping (see below)
c) the exported table shows nulls only in the f_external column. The usage column has perfectly reasonable long numbers.
The POJO:
DataStoreReference
private long id;
private String hash;
private long date;
private long sze;
private long usage;
private int state;
private String external;
private DataStoreContainer container;
followed by generic unmodified getter/setters.
The mapping file:

Turns out it is a bug with the enhanced Hibernate 3.6 MS SQL dialects. If you extend SQLServer2005 or SQLServer2008 dialects, you will have this issue. Using the older SQLServer dialect (which is pretty much what shipped with Hibernate 3.3x) you do not. Probably something to do with paging support introduced. Sigh
