[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-892) HQL parser does not resolve alias in ORDER BY clause

[Jean-François St-Germain (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-892?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=38762#action_38762 ] 

Jean-François St-Germain commented on HHH-892:
----------------------------------------------

wow! it took 5 (FIVE) years to fix such an essential and basic functionality!!!
In the mean time that a stable build is released including this fix, just use the column number instead of its alias...

select a.id as annoying, a.field2 as bug from a order by 2

results will be sorted based on the second column

> 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_
