hql

问题 Is it possible to compare LocalDate with LocalDateTime in HQL/JPQL? This is my query of repository method in spring data which should return amount of orders per required dates. The field deliveryDateTime in Order entity has type LocalDateTime . I want to ignore time part and compare only date part. @Query("SELECT new OrderCountPerDate(DATE(o.deliveryDateTime), COUNT(o.id)) FROM Order o WHERE DATE(o.deliveryDateTime) IN :dates GROUP BY DATE(o.deliveryDateTime) ") List<LocalDate>

问题 I have this query. Translate it from my sql query to hql.

问题 As a followup to this answer(on approach 1 ) I want to go a step further : I want to Filter the grand child objects based on certain criteria's. I tried the following query, but it still does not filter out the objects under the grandchild entity. @Query("select ch from ChildEntity ch " + " join ch.parentEntity pr " + " join fetch ch.grandChildEntities gc " + " where pr.bumId = :bumId and ch.lastExecutionTimestamp in " + "( select max(ch1.lastExecutionTimestamp) from ChildEntity ch1 " + "join

问题 I try use this HQL query: Result.find("SELECT c, ( 3959 * acos( cos( radians(?) ) * "+ "cos( radians( c.latitude ) ) *"+ "cos( radians( c.longitude ) - radians(?) ) +"+ "sin( radians(?) ) * sin( radians( c.latitude ) ) ) ) " + "AS distance FROM City c HAVING distance < ? ORDER BY distance ASC", latitude, longitude, latitude, radius).fetch(); But in result: IllegalArgumentException occured : org.hibernate.hql.ast.QuerySyntaxException: unexpected token: HAVING near line 1, column 204 [SELECT c,

问题 Usually I work with NoResultException to return an "empty" object, e.g. an empty error list or new BigInteger("0"), if I get no results from a TypedQuery. Now it turned out that this sometimes doesn't work. Suddenly getSingleResult() returns null instead of causing a NoResultException, and I don't understand why. Look this example: public BigInteger pointsSumByAccountId(long accountId) { try { TypedQuery<BigInteger> pointsQuery = entityManager.createNamedQuery(Points.SumByAccountId,

问题 I've SQL query: SELECT tag.id, tag.description, tag.`name`, COUNT(question_has_tag.question_id) FROM question_has_tag INNER JOIN question ON question.id = question_has_tag.question_id INNER JOIN tag ON question_has_tag.tag_id = tag.id GROUP BY tag.id All works good. But I need to rewrite it to HQL, some one have any idea? I tried this, but it doesn't work: list = entityManager.createQuery("SELECT " + "t.id, " + "t.description, " + "t.name, " + "COUNT(q.id) " + "FROM Tag t INNER JOIN Question
