---------------------------------

Is there any HQL-solution on this subject? I do not care if someone thinks this is not a bug - i need a HQL solution, instead. Or, at the end, any reasonable solution...

> 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_
