[Hibernate-JIRA] Created: (HHH-3511) Sybase - Column alias in subselect doesn't works
by Juraci Paixao Krohling (JIRA)
Sybase - Column alias in subselect doesn't works
------------------------------------------------
Key: HHH-3511
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3511
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.2.4.sp1
Environment: Branch_3_2_4_SP1_CP with Sybase 15
Reporter: Juraci Paixao Krohling
I could not find any reference in documentation to support it, but it seems that column aliasing in sub-selects isn't supported. I could not find any information in the docs which confirms or denies this, but running the test CriteriaQueryTest#testDetachedCriteriaAsSubQuery can confirm this.
Hibernate generates a query which ends in:
where ? in (select this_.courseCode as y0_ from Course this_ where this_.description like ?)
This fails in Sybase, with this message:
15:29:38,063 WARN JDBCExceptionReporter:77 - SQL Error: 156, SQLState: ZZZZZ
15:29:38,074 ERROR JDBCExceptionReporter:78 - Incorrect syntax near the keyword 'AS'.
Removing all "as" keywords returns the same message, even though the query itself doesn't have it. [1]
Removing the "as $alias" solves the problem.
The working line is:
where courseCode in (select this_.courseCode from Course this_ where this_.description like 'test%')

[Hibernate-JIRA] Created: (HHH-2905) Sybase not allow to use alias in subquery

Sybase not allow to use alias in subquery
-----------------------------------------
Key: HHH-2905
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2905
Project: Hibernate3
Issue Type: Bug
Components: query-criteria
Affects Versions: 3.2.2
Reporter: Sammi Ting
I have the same question as the post in forum:
http://forum.hibernate.org/viewtopic.php?t=949233
However, the forum is just so errorneous that not allow me to register nor display the page.
My problem:
I am using sybase as persistant storage and using Hibernate to perform ORM. Due to Spring implementation, I selected to use DetachedCriteria and want to have a simple subquery to perform a tiny task. However, sybase seems not allow alias in subquery and make my sql invalid (generated by Hibernate). If I try to remove the alias from subquery and run the sql, it returns result gracefully.
Any workaround to disable alias? (I am using sybase dialect)

[Hibernate-JIRA] Commented: (HHH-530) Allow application of filters on subqueries
by Heiko Burchard (JIRA)
[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-530?page=co... ]
Heiko Burchard commented on HHH-530:
------------------------------------
Did someone have a look at the unit test I provided? If this is holds to be a bug, shouldn't this issue be reopened? Or should it be a new one? Or is this handled with the SQL Generation rewrite?
