在HQL中查询时出现以下错误
异常原因：意外AST节点：第1行附近的COUNT
我的疑问如下

@Query("SELECT new com.model.CompanyInfoMapping(c.company_id, c.company_name)"
            + "FROM Company c Inner JOIN c.companyInfo ci INNER JOIN c.portfolioPrivate ppc               "
            + " WHERE (ppc.beschreibung_id ='1'  AND ppc.value = 'Yes') "
            + " OR (ppc.beschreibung_id ='2'  AND ppc.value = 'Yes')" 
            + " GROUP BY c.company_id "
            + " HAVING COUNT(CASE WHEN ppc.value ='Yes' THEN 1  ELSE 0 END) " )

任何提示都将不胜感激。
