[Hibernate-JIRA] Created: (HHH-2650) Allow for an entire Session to be readOnly, add Session.setReadOnly() method

by Gunther Schadow (JIRA)

Allow for an entire Session to be readOnly, add Session.setReadOnly() method ---------------------------------------------------------------------------- Key: HHH-2650 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2650 Project: Hibernate3 Issue Type: Sub-task Components: core Environment: Any Reporter: Gunther Schadow There is a need for read-only applications to avoid any snapshoting of objects if that application never intends to make updates. Such readOnly mode would be the mode in which any object gets loaded into the session, whether directly or from lazy collections. The use case is reporting applications which want to make sure that they don't even accidentally make updates AND that want to save the time it takes to create snapshots because they read through a lot of data very quickly. Our own need is that we have a rich client where we hold read only sessions open for browsing and where we spawn off any change transactions into separate Sessions. Even in change transactions we like to have all objects locked from even accidental updates unless they are explicitly unlocked. A Session.setReadOnly() method would be ideal to do this. It does not appear very hard to make that improvement. We would do it ourselves even if we had some idea if (and under which criteria) our modifications would have a chance to make it into future versions of Hibernate? -- 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: (ANN-632) @IndexColumn doesn't set value of index column

by Dan Allen (JIRA)

@IndexColumn doesn't set value of index column ---------------------------------------------- Key: ANN-632 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-632 Project: Hibernate Annotations Issue Type: Bug Components: documentation Affects Versions: 3.3.0.ga Reporter: Dan Allen I'm sure I will get screamed at for this, but the @IndexColumn just doesn't work with @OneToMany. When I say it doesn't work, it means that I am a reasonable person and I have studied the documentation for at least 4 hours and I just cannot figure out how to make it work. So either the documentation needs to be improved, or there is something wrong with Hibernate. I refuse to believe that I am this stupid. Here is my problem in a nutshell. I have a Person and a collection of Jobs. The Jobs should be an indexed list based on the history that the person holds them. @Entity public class Person { @Id @GeneratedValue private long id; @Column private String name; @OneToMany(cascade=ALL, fetch=LAZY, mappedBy = "job") @IndexColumn(base = 1, name = "order") private List<Job> jobs = new ArrayList<Job>(); // getters and setters } @Entity public class Job { @Id @GeneratedValue private long id; @Column private String name; @ManyToOne @JoinColumn(name="person_id") private Person person; @Column private Integer order; // getters and setters } If I do the following, I get NULL for order. Person person = new Person(); person.setName("Chuck") Job job1 = new Job(); job1.setName("sysadmin") job1.setPerson(person); person.getJobs().add(job1); Job job2 = new Job(); jobs2.setName("network admin") job2.setPerson(person); person.getJobs().add(job2); entityManager.persist(person); Assume that the reason I am not assigning an order is more complex than this example. The point is that we want to see the order column populated with the index of the list. Now, if you give me the business about removing mappedBy, to that I will respond that by removing mappedBy, Hibernate tries to work with a person_job table, which I don't want. I want two tables, one for person and one for job. -- 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-2354) Schema validation too rigid for MySql enums

by Zeljko Trogrlic (JIRA)

Schema validation too rigid for MySql enums ------------------------------------------- Key: HHH-2354 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2354 Project: Hibernate3 Type: Bug Components: metamodel Environment: jboss-seam-1.1.0.GA, MySQL 5 Reporter: Zeljko Trogrlic Enum column type in MySQL is handled as CHAR in their JDBC driver and should be mapped to String Java type. However, Hibernate expects varchar(n) and fails to do the validation. This is how DatabaseMetaData.getColumns describes it: DATA_TYPE=1 TYPE_NAME=enum Note that although TYPE_NAME is enum, DATA_TYPE represents CHAR.

[Hibernate-JIRA] Created: (EJB-277) allow string values for query hints

by Norman Richards (JIRA)

allow string values for query hints ----------------------------------- Key: EJB-277 URL: http://opensource.atlassian.com/projects/hibernate/browse/EJB-277 Project: Hibernate Entity Manager Type: Improvement Reporter: Norman Richards It seems that some string values are not accepted as query hint values in hibernate. In specific, I was trying to convert a simple query that uses setHint("org.hibernate.cacheable", true) to use an XML-defined EntityQuery that uses <framework:entity-query name="allCategories" ejbql="select c from Category c" order="c.name"> <framework:hints> <key>org.hibernate.cacheable</key> <value>true</value> </framework:hints> </framework:entity-query> Unfortunately, this fails with an IllegalArgumentException: Caused by: java.lang.IllegalArgumentException: Value for hint at org.hibernate.ejb.QueryImpl.setHint(QueryImpl.java:160) at org.jboss.seam.framework.EntityQuery.createQuery(EntityQuery.java:114) at org.jboss.seam.framework.EntityQuery.getResultList(EntityQuery.java:41) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) ... Although I didn't try it, I would assume this would also fail from a @QueryHint in on a named query since that annotation only accepts a string value. I don't think this is technically a bug, but it would be very convenient if all the hints could accept string values. -- 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-2905) Sybase not allow to use alias in subquery

by Sammi Ting (JIRA)

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?

[Hibernate-JIRA] Created: (HHH-2077) Providing an escape sequence for Criteria queries

by Tobias Dietl (JIRA)

Providing an escape sequence for Criteria queries ------------------------------------------------- Key: HHH-2077 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2077 Project: Hibernate3 Type: Improvement Components: query-criteria Versions: 3.1.3, 3.2.0 cr1, 3.2.0.cr2, 3.2.0.cr3, 3.2.0.cr4 Environment: Hibernate 3.1.3, MySQL, HSQLDB, Oracle Reporter: Tobias Dietl Up to now, there is no way of setting the escape sequence to use for string comparisions with like for Criteria queries. This is necessary as MySQL on the one hand and HSQLDB / Oracle on the other behave differently... If you want to search for '_abc' in MySQL, you have to use: value like '\\_abc' In Oracle or HsqlDB, you have to use: value like '\_abc' If you want to switch to another escape sequence like '|' , you can set it in HQL with value like '|_abc' escape '|'. Unfortunately, there is no way of setting it for Criteria queries, which would force me to rewrite all my Criteria queries in HQL. It would really be nice if the feature/improvement would be added... -- 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-2407) rework HQL translator

by Steve Ebersole (JIRA)

rework HQL translator --------------------- Key: HHH-2407 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2407 Project: Hibernate3 Type: Improvement Components: query-hql, query-criteria Reporter: Steve Ebersole Assigned to: Steve Ebersole Priority: Blocker Fix For: 3.3 Formalization of the work already started on the HQL_ANTLR_2 branch in SVN. Specifically, split the translation into 4 phases instead of 3 phases (we really sorta, kinda have 4 phases already with the join-post-processor). This is pre-requisite for many requested enhancements to HQL. Also the idea is to consolidate code between HQL and Criteria translation, thus giving Criteria queries all the capabilities available in HQL. -- 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
