hql語句 在from 後不支持 子查詢
1.不能加入除對象之外的屬性
2.如果從多個數據中找到一個特殊的數據,可根據where 判斷進行篩選
如：
SELECT COUNT(*)
FROM C_RegistrationBroadcastSituation as rbsCount
where rbsCount.filmManagementId=rbsAll.filmManagementId
and rbsCount.buyer =rbsAll.buyer)as cou
from C_RegistrationBroadcastSituation as rbsAll
where rbsAll.broadCastDate=(
SELECT min(rbs.broadCastDate)as broadCastDate
FROM C_RegistrationBroadcastSituation as rbs
where rbs.filmManagementId=rbsAll.filmManagementId
and rbs.buyer =rbsAll.buyer
)
//如何把查詢的值 放到 vo 對象中
StringBuffer hql = new StringBuffer("select new com.targ.cftvc.broadcastSituation.vo.BroadcastSituationStatisticsVO(rbsAll,playTime) ");
