I have an interesting thing to implement. I have to implement the following Query in JPA2 without using NativeQuery method.
select smsid, smstimestamp, hphonenumber from db.sms as detail join (select max(smsid) as maxsmsid, max(smstimestamp) as maxtime from db.sms where myrmnid=5 group by hphonenumber order by maxsmsid limit 0,15) as topconv on detail.smstimestamp=topconv.maxtime and detail.smsid = topconv.maxsmsid
How can I do this?
query = entityManager.createQuery("select detail from sms as detail join (select max(m.smsid) as maxsmsid, max(m.smstimestamp) as maxtime from sms as m where m.myrmnid=:myrmnid group by m.hphonenumber order by maxsmsid limit 0,15) as topconv on detail.smstimestamp=topconv.maxtime and detail.smsid = topconv.maxsmsid");
The above statement is getting failed. Please help me with this. Any help is appreciated.
