<code class="java">public class SurveyAnswerStatistics {
  private String answer;
  private Long count;

  // Constructor for object instantiation
}</code>

<code class="java">public interface SurveyRepository extends CrudRepository<Survey, Long> {
    @Query("SELECT new com.path.to.SurveyAnswerStatistics(v.answer, COUNT(v)) FROM Survey v GROUP BY v.answer")
    List<SurveyAnswerStatistics> findSurveyCount();
}</code>

<code class="java">public interface SurveyAnswerStatistics {
  String getAnswer();
  int getCnt();
}</code>

<code class="java">@Query(nativeQuery = true, value =
          "SELECT v.answer AS answer, COUNT(v) AS cnt FROM Survey v GROUP BY v.answer")
    List<SurveyAnswerStatistics> findSurveyCount();
