轉換PostgreSQL的查詢到本機查詢

我想下面的PostgreSQL的查詢轉換到休眠查詢或任何類型的Java支持查詢轉換PostgreSQL的查詢到本機查詢

WITH RECURSIVE tree(parent, idElement) AS 
    (
    --Anchor member definition 
     SELECT e.fk_course_det_id, e.course_det_id,e.course_name 
     FROM course_details AS e 
     WHERE course_det_id =1 
     UNION ALL 
    -- Recursive member definition 
     SELECT d.fk_course_det_id, d.course_det_id,d.course_name 
     FROM tree 
     INNER JOIN course_details AS d 
      ON tree.idElement = d.fk_course_det_id 
      ) 
      SELECT * 
    FROM tree

我只是轉換上面查詢到本機查詢

@Entity 
    @Table(name = "course_details") 
    @NamedNativeQuery(
     name = "getAllChild", 
     query=" WITH RECURSIVE tree(idElement,parent,name) AS"+ 
    "("+ 

     " SELECT e.course_det_id,e.fk_course_det_id,e.course_name"+ 
     " FROM course_details AS e "+ 
     " WHERE e.course_det_id =?1"+ 
     " UNION ALL"+ 

     " SELECT d.course_det_id,d.fk_course_det_id,d.course_name"+ 
     " FROM tree "+ 
     " INNER JOIN course_details AS d"+ 
      " ON tree.idElement = d.fk_course_det_id"+ 
      ")"+ 
      " SELECT * FROM tree", 
    resultClass=CourseDetails.class 
) 
    @Component 
    public class CourseDetails{// 
    ...//}

實現類

@Override 
    public @ResponseBody List<CourseDetails> sectionList(@ModelAttribute("course_details_create") CourseDetails cd, 
      @RequestParam("cdtype") Long cdtype, Model model) { 

     List<CourseDetails> allList = entityManager.createNamedQuery("getAllChild", CourseDetails.class) 
       .setParameter(1, cdtype) 
       .getResultList(); 
return allList;

，但我得到了錯誤 org.postgresql.util.PSQLException：列名course_det_id並沒有到此ResultSet中。

我認爲你不能沒有寫一些JPA供應商特定的功能。但是你可以使用本地查詢和映射到對象：http://www.buzdin.lv/2012/08/recursive-polymorphic-queries -with-jpa.html –

@Rodrigo Menezes你確定嗎？ – BeginnerBro

在一些帖子中有關於這個問題的更多信息：https://stackoverflow.com/questions/3638082/recursive-jpa-query –

經過一番研究，我只是傳遞字符串的SQL查詢本地休眠sqlquery的並根據需要我得到的結果非常完美。

@Override 
    public @ResponseBody List<CourseDetails> sectionList(@ModelAttribute("course_details_create") CourseDetails cd, 
      @RequestParam("cdtype") Long cdtype, Model model) { 

     Session session = getSession(); 
     String query = "WITH RECURSIVE tree(parent, idElement) AS" + "(" + 

       "SELECT e.fk_course_det_id, e.course_det_id,e.course_name,e.course_desc,e.fk_book_id,e.fk_org_id" 
       + " FROM course_details AS e" + " WHERE course_det_id =" + cdtype + " UNION ALL" + 

       " SELECT d.fk_course_det_id, d.course_det_id,d.course_name,d.course_desc,d.fk_book_id,d.fk_org_id AS course_det_id" 
       + " FROM tree" + " INNER JOIN course_details AS d" + " ON tree.idElement = d.fk_course_det_id" + ")" 
       + " SELECT *" + " FROM tree"; 

     SQLQuery qry = session.createSQLQuery(query); 
     qry.setResultTransformer(Criteria.ALIAS_TO_ENTITY_MAP); 
     List<CourseDetails> results = qry.list(); 

     return results; 

    }
