小编use*_*286的帖子

这是我的JPA ENTITY

@Entity
@NamedQueries({  
        @NamedQuery(name = "Question.randQuestion", query = "SELECT q FROM Question AS q ORDER BY     RANDOM")
})
@Table(name = "questions")
public class Question implements Serializable {
.....
}

问题是:

eclipse给了我这个namedQuery的错误.它说:"在FROM子句中没有定义标识变量'RANDOM'"

我也试过RAND()而不是RANDOM和NEWID().

谢谢.
