[hibernate-issues] [Hibernate-JIRA] Created: (HHH-4656) Small patch to support cross joins in Criteria queries

Small patch to support cross joins in Criteria queries ------------------------------------------------------ Key: HHH-4656 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4656 Project: Hibernate Core Issue Type: Patch Components: core Affects Versions: 3.5 Environment: Recent Hibernate trunk, Ubuntu 8.04, MySQL 5.0.51a-3ubuntu5.4 Reporter: Chris Wilson Attachments: hibernate-criteria-cross-join.patch This patch allows you to do a cartesian product (cross join) in a Criteria query, deliberately removing the supplied join conditions, and adding any that you like (prefer) via the withClause parameter of Criteria.createCriteria. For example, it enables you to do: Criteria c = session.createCriteria(Project.class); c.createCriteria("sites", JoinFragment.CROSS_JOIN); returning a row for every Project and every Site, regardless of whether they match or not. I need this to implement some complex SQL queries using Criteria. I could probably use HQL or SQL but I prefer Criteria. The patch includes some changes I made to ANSIJoinFragment's SQL formatting to make the SQL it generates easier to read, which you may prefer to leave out. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
