[Hibernate-JIRA] Created: (HHH-2871) can't specify property of the element in the collection

by Vlad Rechkalov (JIRA)

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

[Hibernate-JIRA] Created: (HHH-2667) 'illegal attempt to dereference collection' when using auto-join

by Martin Kouba (JIRA)

'illegal attempt to dereference collection' when using auto-join ---------------------------------------------------------------- Key: HHH-2667 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2667 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.4.sp1, 3.2.4, 3.2.3 Environment: I have found that behaviour in version 3.2.4.sp1 and 3.2.3 (I didn't test 3.2.4 pre sp1) Database: ORACLE 10g Reporter: Martin Kouba After upgrading to the latest Hibernate version I got this error. I try to use a statement like this from cat c where c.mate.id = 13 the expected resulting SQL should be something like SELECT * FROM CAT C WHERE C.MATE_ID = 13 which is much more performant than making a join from cat c join c.mate m where m.id = 13 which would result in something like that SELECT * FROM CAT C INNER JOIN MATE M ON C.MATE_ID = M.ID WHERE M.ID = 13 This works as expected in 3.1.3, 3.2.0 and 3.2.2 It doesn't work with version 3.2.3 and with 3.2.4.sp1. -- 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-2822) timestamp extraction functions do not work in SAPDBDialect

by Yossi Tamari (JIRA)

timestamp extraction functions do not work in SAPDBDialect ---------------------------------------------------------- Key: HHH-2822 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2822 Project: Hibernate3 Issue Type: Bug Components: query-hql Affects Versions: 3.2.5, 3.2.4.sp1, 3.2.4, 3.2.3, 3.2.2, 3.2.1, 3.2.0.ga, 3.2.0.cr5, 3.2.0.cr4, 3.2.0.cr3, 3.2.0.cr2, 3.2.0 cr1, 3.1.3, 3.2.0.alpha2, 3.2.0.alpha1, 3.1.2, 3.1.1, 3.1, 3.1 rc3, 3.1 rc2, 3.1 rc 1, 3.1 beta 2, 3.1 beta 1, 3.0.5, 3.0.4, 3.0.3, 3.0.2, 3.0.1, 3.0 final, 3.0 rc 1, 3.0 beta 4, 3.0 beta 3, 3.0 beta 2, 3.0 beta 1, 3.0 alpha Environment: SAPDB 7.6 Reporter: Yossi Tamari Priority: Minor There is no registerFunction in the SAPDBDialect for the date extraction SQL functions (extract, day, hour...). Therefore, the inherited registration from Dialect are in effect. However, they all map to extract, which is no supported in SAPDB. The correct implementation is to register the following functions in SAPDBDialect.java: registerFunction( "second", new SQLFunctionTemplate(Hibernate.INTEGER, "second(?1)") ); registerFunction( "minute", new SQLFunctionTemplate(Hibernate.INTEGER, "minute(?1)") ); registerFunction( "hour", new SQLFunctionTemplate(Hibernate.INTEGER, "hour(?1)") ); registerFunction( "day", new SQLFunctionTemplate(Hibernate.INTEGER, "day(?1)") ); registerFunction( "month", new SQLFunctionTemplate(Hibernate.INTEGER, "month(?1)") ); registerFunction( "year", new SQLFunctionTemplate(Hibernate.INTEGER, "year(?1)") ); registerFunction( "extract", new SQLFunctionTemplate(Hibernate.INTEGER, "?1(?3)") ); -- 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-2842) Problem with instantiating components

by Lanna Kim (JIRA)

Problem with instantiating components ------------------------------------- Key: HHH-2842 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2842 Project: Hibernate3 Issue Type: Improvement Components: core Affects Versions: 3.2.5 Environment: Hibernate 3.2.5ga, DB2 8 Reporter: Lanna Kim Attachments: quickfix.zip, school.zip Hi, I am working on a project migrating a legacy application into J2EE environment using Hibernate. Although it has fairly complicated class hierarchy and table structures, we have managed to migrate most of features successfully, thanks to the flexibility of Hibernate. (Thank you for the great work!) However, we have one issue with instantiating dependent objects. Sometimes only parent class knows how to instantiate its dependent objects properly, so these objects need to be created by their parent class. For example, the following persistent class Student has a dependent object studentInfo, which is mapped as as component in the mapping file. -------------------------------------------------- public class Student { private Long id; private StudentInfo studentInfo; public Student() { // instantiate StudentInfo object here with some additional information. studentInfo = new StudentInfo(SchoolHelper.lookupType("C")); } // ... } -------------------------------------------------- public class StudentInfo { private String description; private transient String typeA; private transient String typeB; public StudentInfo() { } public StudentInfo(String type) { this.typeA = SchoolHelper.getTypeA(type); this.typeB = SchoolHelper.getTypeB(type); } // ... -------------------------------------------------- <class name="school.Student" table="STUDENT"> <id name="id" column="STUDENT_ID"> <generator class="native"/> </id> <component name="studentInfo" class="school.StudentInfo"> <property name="description" column="SI_DESC" /> </component> </class> -------------------------------------------------- Only 'description' member is mapped to a database column and other transient members of StudentInfo aren't. These transient members can be set only by using the information passed from its parent class, Student. However, when a Student object is loaded from database, this information (typeA and typeB) becomes null, because the default constructor StudentInfo() is used by Hibernate, and then Student.setStudentInfo() is called to replace the existing (but properly instantiated) studentInfo object. I know it is a Hibernate requirement for all persistent classes to have no-arg default constructors. This is fine, but is it true for all dependent objects as well? Some of our depedent objects are contained in both persistent classes and business logic classes and it is very difficult to separate them. It would be great if Hibernate supports either of following features: 1) <property> can accept a dotted notaton for its name, so that we can access directly the member of the depedent object without having <component>. i.e. <property name="studentInfo.description" column="SI_DESC" />  or, 2) <component> has an option to indicate to reuse the existing instance instead of always creating a new one. i.e. <component name="studentInfo" reuse="true" class="school.StudentInfo> ... </component>  I have attached student.zip to indicate this issue and quickfix.zip for the (rough) hibernate fix so that ComponentType reuses the existing value unless it is null. Any advice or comment would be appreciated. -- 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
