JPA-基于setParameter的按条款分组

Question

我们可以基于setParameter使用动态分组依据子句吗？

select (FLOOR(r.TTF/:binWidth) * :binWidth + :binWidth ) AS TTF,COUNT(r.SerialNumber) AS Count from RMATTFMapping r  where r.GlobalProductId in (select distinct c.GlobalProductID from ProductComponentMapping c where c.Component=:component ) AND r.CalendarMonthStartDate between :start AND :end and NOT (r.TTF in (-999) OR r.TTF is NULL) GROUP BY FLOOR(r.TTF/:binWidth) ORDER BY FLOOR(r.TTF/:binWidth) 

在上述查询中，我必须基于binWidth ( request parameter)使用分组依据，但是我遇到了"ORA-00979: not a GROUP BY expression"异常。
