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
}

Attachment: hhh-5078-fix.txt
This patch adds the test and includes a fix, which is not optimal but will get the job
done; it will bracket expressions like (((2 + 2) + 2) + 2) which is not needed, in other
words, it just adds the parentheses without regards for precedence or associativity.
I've checked the other expression renderers and they appear safe enough, notably the
conjunction and disjunction.
