Question

早上好，我从今天早上开始在DAOImpl方法上遇到这个错误......它突然发生了......

这是我的方法：

public int postiOccupatiParcheggio(Park park) {
        Query pianiQuery = getSession().createQuery("from Piano p where p.park = :park");
        pianiQuery.setParameter("park", park);
        List <Piano> piani = pianiQuery.list();

        Query postiQuery = getSession().createQuery("from Posto p where p.piano in :piani");
        postiQuery.setParameterList("piani", piani);
        List<Posto> posti = postiQuery.list();

        Query query = getSession().createQuery("SELECT count(*) from Occupazione o where o.posto in :posti "
                + "and o.occupied = true and o.dateTime = (select max(oo.dateTime) from "
                + "Occupazione oo where o.posto = oo.posto)");
        query.setParameterList("posti", posti);
        Long r = null;
        int result = 0;
        try {
        r = (Long) query.uniqueResult();
        result = r.intValue();

        } catch(NoResultException nre) {
            result = 0;

        } 
        return result;
    }

我收到此异常

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error
 in your SQL syntax; check the manual that corresponds to your MySQL server
 version for the right syntax to use near ')) and occupazion0_.isOccupied=1 and
 occupazion0_.date_time=(select max(occupazi' at line 1

和hibernate日志告诉：

SQL Error: 1064, SQLState: 42000

我读到这是一个错误，如果你使用一些限制变量名称会发生，但事实并非如此，最重要的是，直到昨天一切都很顺利......

我正在使用MySql 5.7.9并使用此属性： hibernate.dialect = org.hibernate.dialect.MySQLDialect

Hibernate SQLSyntaxErrorException - SQL错误：1064，SQLState：42000
