如何在HQL中为每个计数计算具有不同条件的2个字段

Question

编写HQL时遇到问题。 问题是我希望将这样的东西转移到HQL

 select 
   tb.aca_year, 
   (case when tw.isfulltime = 1 then count(te) end) as fulltime,
   (case when tw.isfulltime = 0 then count(te) end) as parttime
 from timetable tb, teacher te, teacherworktype tw 
  where .............
  group by tb.aca_year
 ................

有什么建议吗？

最诚挚的问候，

Answer 1

您可以这样做：

select tb.aca_year, 
    sum(case when tw.isfulltime = 1 then 1 else 0 end) as fulltime, 
    sum(case when tw.isfulltime = 0 then 1 else 0 end) as parttime
from timetable tb, teacher te, teacherworktype tw 
where ............. 
group by tb.aca_year ................
