[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-2744) QueryException raised for valid SQL query - problems with aliases parsing

[Neil Buesing (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-2744?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=39752#action_39752 ] 

Neil Buesing commented on HHH-2744:
-----------------------------------

I don't understand why this will not be fixed. An alias (as far as I can see) cannot be defined within a quoted string within a sql query.  So, why not fix the parser so it doesn't try to balance check {} if the {} are within a quoted literal in the query.

Native query handling should be as close to pure SQL as possible.  I understand that the alias syntax changes that, but this seems to be something that could easily be fixed.
