This is my Query.Please give the suggession what is the mistake in this query?

data=session.createQuery[from com.claystone.db.Gpsdata where id.mobileunitid = '2090818044' and gpsdate in (select id.gpsdate from com.claystone.db.Gpsdata where id.mobileunitid = '2090818044' ORDER BY id.gpsdate DESC LIMIT 1 )  and gpsstatus='true']

Answer 1

why are you using the subquery? just do it like this :

data=session.createQuery[from com.claystone.db.Gpsdata where id.mobileunitid = '2090818044' and gpsstatus='true' ORDER BY id.gpsdate DESC LIMIT 1]

you might need to take the LIMIT 1 off the end and use .setMaxResults(1) on the query.
