title: Validation failed for query for method JPQL
body: <p>I am implementing a query which return output in custom object. With my implementation, I am getting an error:</p>
  
  <blockquote>
    <p>"method public abstract java.util.List org.degs.repository.ConsolidateresponseRepository.transactions()!"</p>
  </blockquote>
  
  <p>JPQL Repository code:</p>
  
  <pre><code>@Query(value = "SELECT new org.degs.beans.ConsolidateResDB(DATE_FORMAT(ts, '%d-%m-%Y') AS transdate,IFNULL(COUNT(orderreqid),0),IFNULL(COUNT(failamount),0),IFNULL(SUM(amount),0),IFNULL(SUM(successamount),0),IFNULL(SUM(failamount),0),IFNULL(COUNT(successcount),0)) FROM Consolidateresponse GROUP BY DATE_FORMAT(ts, '%d-%m-%Y') ORDER BY ts DESC")
  public List&lt;ConsolidateResDB&gt; transactions();
  </code></pre>
  
  <p><code>ConsolidateResDB</code> bean:</p>
  
  <pre><code>public class ConsolidateResDB {
      String transdate;
      long total;
      long failcount;
      double totalamount; double successamount;
      double failamount;
      long successcount;
  }
  </code></pre>
  
  <p>I have already handled null values in the query itself and getting normal output if I run the same query in mysql db terminal, but while implementing in JPA and Spring Boot still receiving the <code>NullPointerException</code>
  error:</p>
