JPA criteria query numeric expressions produce wrong result (due to wrong bracketing) ------------------------------------------------------------------------------------- Key: HHH-5078 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5078 Project: Hibernate Core Issue Type: Bug Components: entity-manager, query-criteria Affects Versions: 3.5.0-Final Environment: Hibernate-Core 3.5.0-Final, all database platforms Reporter: Christoph Gerkens The combination of quot and diff results in wrong SQL code. E.g.: (2 - 1) / 2 should be evaluated to 0.5 not 1.5 ( which is 2 - (1 / 2). JUnit 4 Test: @Test public void testJpaCriteriaApiQuoteAndDiff() { CriteriaBuilder cb = em.getCriteriaBuilder(); CriteriaQuery<Number> query = cb.createQuery(Number.class); query.from(SystemUser.class); // entity type doesn't matter, but must contain at least one entry for this test case. query.select( // (2 - 1) / 2 cb.quot( cb.diff( cb.literal(BigDecimal.valueOf(2.0)), cb.literal(BigDecimal.valueOf(1.0))), BigDecimal.valueOf(2.0))).distinct(true); Number result = em.createQuery(query).getSingleResult(); assertEquals(0.5d, result.doubleValue(), 0.1d); // (2 - 1) / 2 = 0.5 } -- 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
