Java JPA Queries

i'm trying to select all enteties from a databse where a certain date is older than 7 days. It works fine via SQLyog, but in Java it always throws this error:

[33, 76] The expression is not a valid conditional expression.
[76, 101] The query contains a malformed ending.

This is my query in Java:

SELECT a FROM Applicants a WHERE (a.lastMod <= CURRENT_DATE - INTERVAL 7 DAY) ORDER BY a.applDate ASC

May the problem be the "CURRENT_DATE"-part?

Solution

  • CURRENT_DATE is ok, but INTERVAL 7 DAY is not a valid JPQL expression. You'll need to supply the date as parameter

    WHERE a.lastMod <= :dateParam

    Example: 

    Query q = em.createQuery("SELECT a FROM Applicants a WHERE a.lastMod <= :dateParam ORDER BY a.applDate ASC");
q.setParameter("dateParam", dateParam);
List<Applicants> applicants = (List<Applicants>)q.getResultList();

// or, to avoid casting (thanks to @DavidSN)

TypedQuery<Applicants> q = em.createQuery("SELECT a FROM Applicants a WHERE a.lastMod <= :dateParam ORDER BY a.applDate ASC", Applicants.class);
q.setParameter("dateParam", dateParam);
List<Applicants> applicants = q.getResultList();
