java - Mistake in HQL query while creating reports through hibernate projection -

-

i had following query working fine had convert hibernate projection performance issues.

namedquery = " select o orderjob o "

was converted to:-

string hqlquery = "select "          + "new jobauditlistvo( o.jobdate, o.jobtype, customer.name, job.street, payment.description, p.paid,o.invoice) "          + " orderjob o   "          + " join  o.order ordr "         + " join ordr.customer customer "         + " join  o.jobaddress job "         + " join o.payment p"         + " join p.paymentreceivedmethod payment"; getentitymanager().createquery(hqlquery).getresultlist();

but list returning 0 results. while name query return 2 results.

i have got answer. both queries absolutely equivalent. problem had use left join instead of simple join. because entities returning null.
