wrongly predicted param type in HQL ----------------------------------- Key: HHH-3520 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3520 Project: Hibernate Core Issue Type: Bug Components: query-hql Affects Versions: 3.3.1 Reporter: Gregory Klimov Consider class CategoryCode class with property 'code' of type Integer. Then such a code snippet: Query query1 = session.createQuery("from CategoryCode where 'Hello world!' + code + 14 = ?"); query1.setParameter(0, "Test"); query1.list(); Its execution produces sql (which is absolutely correct): select ... from category_codes categoryco0_ where 'Hello world!'+categoryco0_.code+14=? but mapping parameter gives error: 20:21:01,504 <> [main] INFO IntegerType:140 - could not bind value 'Test' to parameter: 1; java.lang.String cannot be cast to java.lang.Integer Exception in thread "main" java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Integer at org.hibernate.type.IntegerType.set(IntegerType.java:41) at org.hibernate.type.NullableType.nullSafeSet(NullableType.java:136) at org.hibernate.type.NullableType.nullSafeSet(NullableType.java:116) at org.hibernate.param.PositionalParameterSpecification.bind(PositionalParameterSpecification.java:39) at org.hibernate.loader.hql.QueryLoader.bindParameterValues(QueryLoader.java:491) at org.hibernate.loader.Loader.prepareQueryStatement(Loader.java:1563) -- 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
