hql 语句不知道怎么拼的，求解，拜托了

Question

sql语句是： select * from COURSE where course_grade='高三' order by last_date desc
我写的hql语句是： "from Course as a where a.courseGrade="+"'高三'"+"0rder by a.lastDate desc"

但是报这个错：org.hibernate.hql.ast.QuerySyntaxException: unexpected token: 0 near line 1, column 66 [from com.mstf.happyStudy.po.Course as a where a.courseGrade='高三'0rder by a.lastDate desc]

个位大神求解，感觉应该很简单，但是我找不到了

Answer 1

from Course as a where a.courseGrade="+"'高三'"+"0rder by a.lastDate desc Order by 那个空下格看看
