    * @IdClass 혹은 @EmbeddedId 같은 복합키를 사용하면서 count() 쿼리를 사용할 때 오류가 발생한다.
    * 쿼리가 <code>count((follow0_.FOLLOWING_ID, follow0_.USER_ID))</code> 이런식으로 생성된다.
    * Hibernate 4.1로 바꾸면 해결된다.

===== Query Comment =====
  * [[http://stackoverflow.com/questions/3196975/how-to-put-a-comment-into-hql-hibernate-query-language|How to put a comment into hql hibernate query language]]<code>
<property name="hibernate.use_sql_comments">true</property>

Query query = ...;
query.setComment("Some comment here");
</code>

===== Lazy Loading Field Load =====
  * Lazy Loading 필드를 강제로 바로 로딩하고자 한다면,
  * ''Hibernate.initialize(entity.getLazyCollection());'' 형태를 사용해본다.

===== ":" Escape =====
  * [[https://hibernate.atlassian.net/browse/HHH-2697|[HHH-2697] Can't use := for variable assignment within a SQL-Statement - Hibernate JIRA]]
  * SQL 문장 자체에 ":"이 있을 경우 HQL의 파라미터 매핑 ":"과 혼동이 있을 수 있다. 이때 SQL 문장의 ":"는 ''\\:''으로 이스케이프하면 된다.<code sql>
SELECT k.`news_master_id` AS id, @row \\:= @row + 1 AS rownum 
    FROM keyword_news_list k 
    JOIN (SELECT @row \\:= 0) r 
    WHERE k.`keyword_news_id` = :kid
ORDER BY k.`news_master_id` ASC
</code>
