given following classes: class user { @onetomany set<transaction> transactions } class transaction { bigdecimal money; } i'm stumped how perform aggregate, functions don't appear available on following query: quser $user = quser.user; qtransaction $transaction = qtransaction.transaction; query().from($user) .innerjoint($user.transactions, $transaction) .where($user.eq(myuser)) // what? as bonus -- possible if money persisted joda money type, rather bigdecimal? (i'm using usertype's joda money support facilitate persistence) something should work quser $user = quser.user; qtransaction $transaction = qtransaction.transaction; query().from($user) .innerjoint($user.transactions, $transaction) .where($user.eq(myuser)) .singleresult($transaction.money.sum()); querydsl doesn't have (yet) direct support joda money, using joda money sum() method won't available directly.

how can construct clause of objectquery querying time part of datetime column? i've tried following it's not working. invalid exception on convert. objectquery<item> _query = itementities.createquery<item>("item"); _query = _query.where("convert(varchar,it.start_time,114) > '{0}'", starttime.timeofday); also, i'm using oracle database. tried to_char instead of convert , still same error. thanks. you should able time portion date using to_char , subsequently converting system type e.g. to_date(to_char(it.start_time,'hh24:mi:ss'), 'hh24:mi:ss') dual if objectquery doesn't support to_char try using extract , build time manually e.g. to_date(extract(hour it.start_time) || ':' || extract(minute it.start_time) || ':' || extract(second it.start_time) dual, 'hh24:mi:ss');
