How i can convert this mysql statement to hql
select invisit, notinVisit
FROM(
select COUNT(*) as invisit from consultations cons join patients p
on cons.patient_id = p.id
where cons.datefin > now()) as A
JOIN
( select COUNT(*) as notinVisit from consultations cons join patients p
on cons.patient_id = p.id
where cons.datefin < now()) as B
my try was
"select com.organ.project.service.DTO.PatientsByInConsultationDTO(invisit, notinVisit)\n" +
"FROM(\n" +
"select COUNT(*) as invisit from Consultation cons join Patient p \n" +
"on cons.patient.id = p.id\n" +
"where cons.datefin > now()) as A\n" +
"JOIN \n" +
"( select COUNT(*) as notinVisit from Consultation cons join Patient p \n" +
"on cons.patient.id = p.id\n" +
"where cons.datefin < now()) as B\n"
but i got this error:
...org.hibernate.hql.internal.ast.QuerySyntaxException: unexpected token: ( near line 2, column 5...
turned out that hql does not support subqueries
ps: i need the invisit , notinVisit props as constructor params to return an object containing the result
Try to use this
select new com.organ.project.service.DTO.PatientsByInConsultationDTO(
sum(case when cons.datefin > now() then 1 else 0 end) as invisit,
sum(case when cons.datefin < now() then 1 else 0 end) as notinVisit)
from Consultation cons join Patient p on cons.patient.id = p.id
group by cons.id
