Pam Callaway commented on HHH-892:
----------------------------------

Hi, it would be very nice if this were fixed.  I have a normal SQL query that I want to do, that I can't figure out how to do without ordering by an alias.  Simple in SQL.  Shouldn't it be possible to also do it in HQL?

> 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_
