Brian Rozmierski commented on HHH-2591:
---------------------------------------
I tried to do some digging through the source and while some changes, perhaps, in/around
org.hibernate.sql.JoinFragment may resolve some of the issues, the HQL parsed queries also
require QueryJoinFragment to reflect these changes. While I can override the JoinFragment
used via the Dialect, I can't seem to be able to override the QueryJoinFragment
without compiling a custom build of hibernate.
MySQL 5.0.12+ JOIN Syntax Changed
---------------------------------
Key: HHH-2591
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HHH-2591
Project: Hibernate3
Issue Type: Bug
Components: query-hql, query-sql
Affects Versions: 3.2.1, 3.2.3
Environment: Tested with Hibernate Core 3.2.1 and 3.2.3, MySQL 5.0.27, 5.0.33,
5.0.37
Reporter: Brian Rozmierski
Priority: Critical
With 5.0.12 MySQL changed the JOIN syntax to be SQL:2003 compliant. (See MySQL 5.0.12
Release Notes at
http://dev.mysql.com/doc/refman/5.0/en/news-5-0-12.html and JOIN syntax
information at
http://dev.mysql.com/doc/refman/5.0/en/join.html for more information)
Previous to this change the following query was valid:
SELECT * FROM t1, t2 JOIN t3 ON (t1.i1 = t3.i3);
Now it must be written as:
SELECT * FROM (t1, t2) JOIN t3 ON (t1.i1 = t3.i3);
or
SELECT * FROM t1 JOIN t2 JOIN t3 ON (t1.i1 = t3.i3);
