[Hibernate-JIRA] Updated: (HHH-1088) Add support for projections using composite keys and components

by Gail Badner (JIRA)

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1088?page=c... ] Gail Badner updated HHH-1088: ----------------------------- Issue Type: Improvement (was: Bug) Summary: Add support for projections using composite keys and components (was: IdentifierProjection does not work with composite keys) > Add support for projections using composite keys and components > --------------------------------------------------------------- > > Key: HHH-1088 > URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1088 > Project: Hibernate Core > Issue Type: Improvement > Components: query-criteria > Affects Versions: 3.1 rc2 > Reporter: Max Muermann > Assignee: Gail Badner > Fix For: 3.5.0.Next > > Attachments: CompositeIdProjection.java, CriteriaLoader.java > > > When working with Criteria queries, the IdentifierProjection breaks if the entity has a composite key. > In IdentifierProjection.java: > public String toSqlString(Criteria criteria, int position, CriteriaQuery criteriaQuery) > throws HibernateException { > StringBuffer buf = new StringBuffer(); > String[] cols = criteriaQuery.getIdentifierColumns(criteria); > for ( int i=0; i<cols.length; i++ ) { > buf.append( cols[i] ) > .append(" as y") > .append(position + i) > .append('_'); > } > return buf.toString(); > } > This method does not add commas as separators between the column names. Easily fixed by adding > if (i<col.length-1) > buf.append(","); > as the last statement inside the loop. > However, this leads to another problem: > the type returned by IdentifierProjection.geType is the (single) type of the composite id component. The query will however return the property values of the id component without a mapping step. -- 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-5034) Make CriteriaImpl.uniqueResult() more robust

by Tomas Pollak (JIRA)

Make CriteriaImpl.uniqueResult() more robust -------------------------------------------- Key: HHH-5034 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5034 Project: Hibernate Core Issue Type: Improvement Components: core Affects Versions: 3.3.1 Reporter: Tomas Pollak We are using Sybase for generating a query that has a COUNT(*) and ORDER BY. Granted, the 'order by' doesn't have any semantic effect, but it's a dynamically generated query, and we need to know the total count as well as the actual result. The problem is that Sybase returns many rows for such a query, and the uniqueResult() fails with a NonUniqueResultException. Although every returned row contains an Integer with the same value, they are different instances. We could modify the AbstractQueryImpl.uniqueElement(List list) as follows: static Object uniqueElement(List list) { int size = list.size(); if (size == 0) return null; Object first = list.get(0); for (int i = 1; i < size; i++) { if (!safeEquals(first, list.get(i))) { throw new NonUniqueResultException(list.size()); } } return first; } static boolean safeEquals(Object first, Object second) { if (first instanceof Integer && second instanceof Integer) { return ((Integer)first).compareTo((Integer)second) == 0; } return first == second; } That would solve our issue.

[Hibernate-JIRA] Created: (HHH-5009) Support NOWAIT for "SELECT ... FOR UPDATE" with JPA interfaces

by Sergey Vladimirov (JIRA)

Support NOWAIT for "SELECT ... FOR UPDATE" with JPA interfaces -------------------------------------------------------------- Key: HHH-5009 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5009 Project: Hibernate Core Issue Type: Improvement Affects Versions: 3.5.0-CR-2 Environment: Oracle / Derby Reporter: Sergey Vladimirov Test case description: - DERBY dialect extended to add /* +NOWAIT */ SQL comment to check if it's actually used. - if it's working, log should contain --- "org.hibernate.SQL DEBUG select entity0_.id as id0_0_, entity0_.value as value0_0_ from entities entity0_ where entity0_.id=? for update with rs /* +NOWAIT */" -- but currently it --- "org.hibernate.SQL DEBUG select entity0_.id as id0_0_, entity0_.value as value0_0_ from entities entity0_ where entity0_.id=? for update with rs" It seems LockOptions (like "javax.persistence.lock.timeout") are lost when converting from JPA to Hibernate. The possible place of error, from my point of view, is loadFromDatasource() (DefaultLoadEventListener:499), where persister is loaded depending only on LockMode without paying attention to lockOptions (including timeout). -- 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
