如何在NamedQuery中编写NamedQuery Haversine公式？

Question

我想在haversine公式的查询下运行为NamedQuery，但我不知道如何纠正它。

set @orig_lat = 37.334542;
set @orig_lon = -121.890821;
set @dist = 10;

select  *,
        3956 * 2 * ASIN(SQRT(POWER(SIN((@orig_lat - abs(mlatitude)) * pi() / 180 / 2), 2) 
          + COS(@orig_lat * pi() / 180) * COS(abs(mlatitude) * pi() / 180) * POWER(SIN((@orig_lon - mlogitude) * pi() / 180 / 2), 2))) as distance
from user_gps_location
having distance < @dist
ORDER BY distance

我将查询运行到mysql中，对我来说很好用，但是当我将以下查询写为NamedQuery时，它给了我错误：

UserGpsLocation users = (UserGpsLocation)em.createQuery("select (3956*2*ASIN(SQRT(POWER(SIN((?1-abs(u.mlatitude))*pi()/180/2),2)+COS(?1*pi()/180) * COS(abs(u.mlatitude)* pi()/180) *POWER(SIN((?2 -u.mlogitude)* pi()/180/2),2)))) as distance from UserGpsLocation u having distance < :dist ORDER BY distance")
      .setParameter(1, mlatitude)
      .setParameter(2, mlogitude)
      .setParameter("dist", 10)
      .getResultList();

例外：

javax.servlet.ServletException: java.lang.IllegalArgumentException: An exception occurred while creating a query in EntityManager: 
Exception Description: Syntax error parsing the query [select (3956*2*ASIN(SQRT(POWER(SIN((?1-abs(u.mlatitude))*pi()/180/2),2)+COS(?1*pi()/180) * COS(abs(u.mlatitude)* pi()/180) *POWER(SIN((?2 -u.mlogitude)* pi()/180/2),2)))) as distance from UserGpsLocation u having distance < :dist ORDER BY distance], line 1, column 19: unexpected token [(].
Internal Exception: NoViableAltException(83@[()* loopback of 383:9: (d= DOT right= attribute )*])

谁能帮助我，告诉我这是怎么回事？

终于能够找到解决方案。我使用createNativeQuery代替createQuery，它解决了我的问题。
