Pierre commented on HHH-892:
----------------------------
It would really nice to see a solution for this issue. The fact is on large slow query you
don't want to repeat the subquery. Without a proper way to alias these subqueries,
they bexome useless, at least if put in the select part of the query. The only solution is
to switch back to SQL...
HQL parser does not resolve alias in ORDER BY clause

Key: HHH-892
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-892
Project: Hibernate3
Issue Type: Bug
Components: query-hql
Affects Versions: 3.0.5
Environment: Hibernate 3.0.5, MySQL, Tomcat
Reporter: Guido Laures
Priority: Minor
When using an alias for an ORDER BY clause this is not always correctly resolved.
Example:
SELECT SUM(A.x) AS mySum FROM MyClass AS A GROUP BY A.y ORDER BY mySum
does not work because "mySum" is not resolved in the ORDER BY clause which
results in an exception telling that mySum is an unknown column.
Workaround (not to say "hack") is using:
SELECT SUM(A.x) AS mySum FROM MyClass AS A GROUP BY A.y ORDER BY col_0_0_
