[hibernate-issues] [Hibernate-JIRA] Closed: (HHH-5449) Versioned HQL update might issue incorrect SQL

Versioned HQL update might issue incorrect SQL ---------------------------------------------- Key: HHH-5449 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5449 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.5.4 Environment: Hibernate 3.5.4 and MySQL. Reporter: Stian Brattland Assignee: Steve Ebersole Priority: Minor Fix For: 3.6.0.Beta3, 3.5.5 Time Spent: 19m Remaining Estimate: 0h When executing a versioned HQL update, the version column (java.util.Calendar) is updated using 'updated=updated+1'. Some MySQL versions will throw an exception whenever the incremented value ended with 59. For instance, if the previous version value was '2010-03-12 13:00:59', then MySQL will throw an exception as the incremented value would be '2010-03-12 13:00:60' (see http://dev.mysql.com/doc/refman/5.0/en/time-zone-leap-seconds.html for more on this). In this case, Hibernate would throw the exception 'SEVERE: Data truncation: Incorrect datetime value: '20100302130060.000000' for column 'updated' at row 1'. I've received feedback on this issue through the Hibernate forum which indicates that this might be a bug (https://forum.hibernate.org/viewtopic.php?f=1&t=1006238) ** Entity.hbm.xml ** <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <class name="com.tracker.robot.db.entities.Entity" table="track"> <id column="id" length="36" name="id" type="java.lang.String" /> <version column="updated" name="updated" type="java.util.Calendar" unsaved-value="null" /> <property column="title" length="255" name="title" type="java.lang.String"/> </class> </hibernate-mapping> ** Entity.java ** import java.util.Calendar; public class Entity { private String id; private String title; private Calendar updated; public Entity() { } public String getId() { return id; } public void setId(String id) { this.id = id; } public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } public Calendar getUpdated() { return updated; } public void setUpdated(Calendar updated) { this.updated = updated; } } ** TestCode ** currentSession.beginTransaction(); Query q = currentSession.createQuery("update versioned Entity e set e.title = :title where e.id = :id"); q.setString("title", "TEST"); q.setString("id", "000059e4-8b71-41c1-81f2-5cacabba5554"); q.executeUpdate(); currentSession.getTransaction().rollback();
