[Hibernate-JIRA] Created: (HHH-3316) If expression support in the criteria API

by Avlesh Singh (JIRA)

If expression support in the criteria API ----------------------------------------- Key: HHH-3316 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3316 Project: Hibernate3 Issue Type: Improvement Components: query-criteria Environment: Hibernate 3, MySQL 4.1 Reporter: Avlesh Singh Priority: Minor MySQL supports IF() as one of the Control Flow Structures. I am not too sure if other dialects support an equivalent. This is how it works - SELECT IF(1>2,2,3); -> 3 To the best of my knowledge, there is no implementation in the Restrictions/Expression class for this control structure. Underneath is what I am talking about this implementation in the Expression class public static org.hibernate.criterion.Criterion ifExpression(org.hibernate.criterion.Criterion criterion, java.lang.Object trueValue, java.lang.Object falseValue){} for which usage would typically look like this- Criteria queryCriteria = session.createCriteria(MyBean.class); queryCriteria.add(Expression.ifExpression(Expression.isNull("myProperty"), "myProperty", new Date())); the bean definition is underneath - class MyBean{ private Date myProperty; } I would love to hear from others on this. -- 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

[Hibernate-JIRA] Created: (HBX-1062) Hibernate Tools - JUnit tests has a lot of errors with Oracle & MySQL test connection

Hibernate Tools - JUnit tests has a lot of errors with Oracle & MySQL test connection -------------------------------------------------------------------------------------- Key: HBX-1062 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-1062 Project: Hibernate Tools Issue Type: Patch Affects Versions: 3.2.1 Reporter: Vitali Yemialyanchyk Priority: Minor Attachments: JBIDE-2229_20080529.zip More description is here - http://jira.jboss.com/jira/browse/JBIDE-2229. opensource.atlassian.com is a right place for the issue - so I put patch here. Now junits should work at least for 3 rdbs: Oracel, MySQL & HSQL. Also it is good example for some differences of these rdbs and subtle differences in use hibernate tools with these rdbs. -- 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

[Hibernate-JIRA] Created: (HHH-3315) Criteria API to accept SQL strings in the orderBy clause

by Avlesh Singh (JIRA)

Criteria API to accept SQL strings in the orderBy clause -------------------------------------------------------- Key: HHH-3315 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3315 Project: Hibernate3 Issue Type: Improvement Components: query-criteria Environment: Hibernate3, MySQL 4.1 Reporter: Avlesh Singh Priority: Minor The criteria interface accepts an "Order" in the addOrder method to sort the resultset. This is how it currently works: Criteria queryCriteria = session.createCriteria(MyBean.class); queryCriteria.addOrder(Order.asc("myBeanProperty")); In my specific case, I needed a sql expression instead of a property name. The Order class had no specific method (unlike the Expression class) to use a sql string instead of the "property" itself. I would have loved to see a public static org.hibernate.criterion.Order sql(java.lang.String sqlString){} implementation in the Order class. Alternatively, The Criteria interface can have this method - org.hibernate.Criteria addOrder(java.lang.String sqlString); I feel its a nice to have feature. -- 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

[Hibernate-JIRA] Created: (HSEARCH-202) Avoid many maps lookup in Workspace

by Sanne Grinovero (JIRA)

Avoid many maps lookup in Workspace ----------------------------------- Key: HSEARCH-202 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-202 Project: Hibernate Search Issue Type: Improvement Reporter: Sanne Grinovero Assignee: Sanne Grinovero Priority: Minor As discussed on dev list: Workspace contains many maps to needed objects, all having the same key "DirectoryProvider"; also locks are kept in an array; Wouldn't it be easier to have a single map, returning a container object with all needed stuff; This object could be passed to all other methods instead of the dir.provider and avoid more gets on the maps. Also some locking code could go "local" in this container class, I've some difficulty in tracking the lock sequences. -- 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

[Hibernate-JIRA] Commented: (HHH-1661) merge of a deleted object results in a insert?

Please could you consider this pacth and try to close this bug?

I tested this, and it seems ok for me.

Using that same object in another session and call merge results in the object being inserted into the database. Here's the sample code: > Session session = factory.getCurrentSession(); > session.beginTransaction(); > MyClass obj = (MyClass)session.load(MyClass.class, new Integer(10)); > session.delete(obj); > session.getTransaction().commit(); > session = factory.getCurrentSession(); > session.beginTransaction(); > session.merge(obj); > session.getTransaction().commit(); > Since the object is already deleted, merge could not find it and thus proceeds with a INSERT. Shouldn't it throw an exception instead? -- 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
