HibernateException: Ошибки в именованных запросов: FindPostWithComments

Question

В моем приложении Spring 4 У меня есть проблема с названием родного запроса:

@NamedNativeQuery(name = "FindPostWithComments", query = 

    " SELECT * FROM (" 
+ "  SELECT p.*, " 
+ "  MATCH (description) AGAINST ('text') AS score " 
+ "  FROM posts as p" 
+ "  WHERE MATCH (description) AGAINST ('text') > 0 " 
+ "  LIMIT 0, 10 " 
+ " ) p LEFT JOIN (" 
+ "  SELECT c.*, " 
+ "   @rownumber := CASE WHEN @post_id = post_id THEN @rownumber + 1 ELSE 1 END AS n, " 
+ "   @post_id := post_id " 
+ "  FROM comments c, " 
+ "  (SELECT @rownumber := 0, @post_id := 0) r " 
+ "  WHERE MATCH (content) AGAINST ('text') > 0 " 
+ "  ORDER BY c.last_edited DESC, post_id DESC " 
+ " ) c ON p.post_id = c.post_id " 
+ " WHERE c.post_id IS NULL OR n BETWEEN 1 and 3 " 
+ " ORDER BY score DESC " 

, resultSetMapping = "PostWithComments") 

@SqlResultSetMappings({ 
    @SqlResultSetMapping(
     name = "PostWithComments", 
     entities = { 
      @EntityResult(entityClass = Post.class, fields = { 
        @FieldResult(name = "id", column = "p.post_id"), 
        @FieldResult(name = "userId", column = "p.user_id"), 
        @FieldResult(name = "type", column = "p.type_id"), 
        @FieldResult(name = "description", column = "p.description"), 
        @FieldResult(name = "link", column = "p.link"), 
        @FieldResult(name = "dateCreated", column = "p.date_created"), 
        @FieldResult(name = "lastEdited", column = "p.last_edited"), 
        @FieldResult(name = "totalVotes", column = "p.total_votes"), 
        @FieldResult(name = "totalComments", column = "p.total_comments")     
       } 
      ), 
      @EntityResult(entityClass = Comment.class, fields = { 
        @FieldResult(name = "id", column = "c.comment_id"), 
        @FieldResult(name = "post", column = "c.post_id"), 
        @FieldResult(name = "userId", column = "c.user_id"), 
        @FieldResult(name = "dateCreated", column = "c.date_created"), 
        @FieldResult(name = "lastEdited", column = "c.last_edited"), 
        @FieldResult(name = "content", column = "c.content"), 
        @FieldResult(name = "totalVotes", column = "c.total_votes") 
       }    
      )   
     } 
    ) 
}) 

Это дает сбой при запуске приложения с исключением следующего:

Какова возможная причина?

Этот запрос отлично работает из Workbench MySQL.

Answer 1

Я нашел причину самостоятельно. Мне нужно добавить двойные косые черты перед каждым знаком двоеточия, поэтому окончательный запрос должен выглядеть так:

" SELECT * FROM (" 
+ "  SELECT p.*, " 
+ "  MATCH (description) AGAINST (:term) AS score " 
+ "  FROM posts as p" 
+ "  WHERE MATCH (description) AGAINST (:term) > 0 " 
+ "  LIMIT 0, 10 " 
+ " ) p LEFT JOIN (" 
+ "  SELECT c.*, " 
+ "   @rownumber \\:= CASE WHEN @post_id = post_id THEN @rownumber + 1 ELSE 1 END AS n, " 
+ "   @post_id \\:= post_id " 
+ "  FROM comments c, " 
+ "  (SELECT @rownumber \\:= 0, @post_id \\:= 0) r " 
+ "  WHERE MATCH (content) AGAINST (:term) > 0 " 
+ "  ORDER BY c.last_edited DESC, post_id DESC " 
+ " ) c ON p.post_id = c.post_id " 
+ " WHERE c.post_id IS NULL OR n BETWEEN 1 and 3 " 
+ " ORDER BY score DESC "
