Issues with aggregation queries using Date objects -------------------------------------------------- Key: ISPN-5787 URL: https://issues.jboss.org/browse/ISPN-5787 Project: Infinispan Issue Type: Bug Affects Versions: 8.0.1.Final, 8.1.0.Alpha1 Reporter: Jakub Markos Assignee: Adrian Nistor Fix For: 8.1.0.Alpha2, 8.0.2.Final I found 2 problems, not sure if they have a common cause: 1. This query {code} Query q = qf.from(getModelFactory().getTransactionImplClass()) .select("date") .having("date").between(makeDate("2013-02-15"), makeDate("2013-03-15")).toBuilder() .groupBy("date") .build(); List<Object[]> list = q.list(); {code} fails with {code} org.hibernate.hql.ParsingException: HQL000002: The query SELECT _gen0.date FROM org.infinispan.query.dsl.embedded.testdomain.hsearch.TransactionHS _gen0 WHERE (date >= Fri Feb 15 01:00:00 CET 2013) AND (date <= Fri Mar 15 01:00:00 CET 2013) is not valid; Parser error messages: [[statement, statementElement, selectStatement, queryExpression, querySpec, whereClause, logicalExpression, expression, logicalOrExpression, logicalAndExpression, negatedExpression, equalityExpression, relationalExpression, concatenation, additiveExpression, multiplyExpression, unaryExpression, atom]: line 1:116 mismatched token: [@35,116:118='Feb',<75>,1:116]; expecting type RIGHT_PAREN]. {code} The query works after removing the groupBy. It also partially works in remote mode (running in RemoteQueryDslConditionsTest) - the query is parsed, but still doesn't return the result as a Date object. 2. This query {code} Query q = qf.from(getModelFactory().getTransactionImplClass()) .select(Expression.count("date"), Expression.min("date")) .having("description").eq("Hotel").toBuilder() .groupBy("id") .build(); List<Object[]> list = q.list(); {code} returns in the 2nd column the internal representation of the Date (i.e. 20130227000000000) instead of an object. Selecting only the minimum, select(Expression.min("date")), the query returns a Date object. Both queries are supposed to be run inside the QueryDslConditionsTest test class.
