the user forum would be more correct.
but a small tip is that jira and documentation contains notes
on the fact that you need to list all parts of the composite id to
make it work.
/max
So I sent an email to this list yesterday about an issue I encountered
where I get malformed SQL when I make an HQL createQuery() call
containing an "order by" clause which refers to a composite ID. I
haven't gotten any responses to that email, but I've dived into the
Hibernate source and am trying to fix it myself.
I'm trying to understand how Hibernate takes an HQL query, relates it to
a mapping (in this case a composite ID), expands that mapping to get its
contents (namely the different keys involved in the composite ID
mapping) and translates that mapping into SQL. I've been looking at the
ANTLR grammars involved and I see how the SQL queries are constructed,
but I don't understand how the parser, upon seeing an order by clause
that involves a composite key gets interpreted by the query engine and
expanded into a SQL query. Can anyone shed some light on this, or give
me a starting point? This is my first time looking at the Hibernate
source; I'm kind of trying to find my feet. Any help would be greatly
appreciated.
Thank you!
