can't specify property of the element in the collection ------------------------------------------------------- Key: HHH-2871 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2871 Project: Hibernate3 Issue Type: Bug Components: query-sql Affects Versions: 3.2.5 Reporter: Vlad Rechkalov Attachments: SQLQueryParser.java In according to Hibernate documentation (topic 16.1.4.1. Alias and property references) collection properties can be specified a few ways: All properties of the the collection {[aliasname].*} All properties of the element in the collection {[aliasname].element.*} Property of the element in the collection {[aliasname].element.[propertyname]} But the last way doesn't work. Example: There are two entities: Program and Document. Program has one-to-many inverse collection of Documents. Program int getId() List<Document> getDocuments() // one-to-many inverse collection Document int getId() String getTitle() Program getParent() // many-to-one association Trying to select Program and fetch collection of Documents: select p.id as {p.id}, d.program_id as {d.key}, d.id as {d.element}, d.id as {d.element.id}, d.title as {d.element.title}, d.program_id as {d.element.program} from ... SQLQuery q = session.createSQLQuery q.addEntity("p", Program.class); q.addJoin("d", "p.documents"); q.list(); // throws exception There is a simple way to fix this bug: class SQLQueryParser method resolveCollectionProperties instead of code (line 140) else if ( "element.*".equals( propertyName ) ) { return resolveProperties( aliasName, "*" ); } write else if( propertyName.startsWith(ELEMENT_PREFIX) ) { return resolveProperties( aliasName, propertyName.substring(ELEMENT_PREFIX.length()) ); } comments: ELEMENT_PREFIX is defined as private static final String ELEMENT_PREFIX = "element."; The fixed file is attached. -- 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
