Aggregation functions should ignore NULL values ----------------------------------------------- Key: ISPN-5732 URL: https://issues.jboss.org/browse/ISPN-5732 Project: Infinispan Issue Type: Bug Affects Versions: 8.0.0.Final Reporter: Jakub Markos Assignee: Adrian Nistor Fix For: 8.0.1.Final For example, this query returns 3 (in QueryDslConditionsTest) {code} public void testCountNull() { QueryFactory qf = getQueryFactory(); Query q = qf.from(getModelFactory().getUserImplClass()) .select(Expression.count("age")) .build(); {code} while only 1 value is non-null. It might be good to behave like JPA, which ignores NULL values: "Null values are eliminated before the aggregate function is applied, regardless of whether the keyword DISTINCT is specified." http://download.oracle.com/otn-pub/jcp/persistence-2.0-fr-eval-oth-JSpec/...
