'in elements' does not work on ElementCollections of Enums ---------------------------------------------------------- Key: HHH-5159 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5159 Project: Hibernate Core Issue Type: Bug Components: core, entity-manager, query-hql Affects Versions: 3.5.1, 3.3.2 Environment: Oracle 10, Hibernate 3.5.1-Final Reporter: Peer Hartmann Attachments: bugreport-mvn.zip When performing a query with an 'in elements' clause and an enum typed parameter, hibernate does not correctly set the parameter value for the underlying SQL. Here is an example (HQL) query: select e from Employee e where :function in elements( e.jobFunctions ); Hibernate makes the following SQL of that (correct) Hibernate: select employee0_.id as id9_, employee0_.name as name9_ from Employee employee0_ where ? in (select jobfunctio1_.jobfunction from employee2jobfunction jobfunctio1_ where employee0_.id=jobfunctio1_.employeeId) ...but sets the parameter wrong as it uses toString instead of the name of the enum: [LogPreparedStatement] DEBUG - executing PreparedStatement: 'select ... from employee2jobfunction ...' with bind parameters: {1=[B@2eb6fb} the exmaple uses an employee entity class with an ElementCollection of JobFunction-enum entries. See the attached zip-file for details. The same query works when using an entity instead of an enum. -- 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
