是否可以使用hql?
仅加入第一行(或仅加入任何其他行但只加一行)select
config.id, mg.modelGroupName, min(deliveryType.id)
from
NotificationConfig config, NotificationConfigEntry configEntry, SettlementModelGroup mg
join
configEntry.notificationConfigEntryPK.user user
join
configEntry.notificationConfigEntryPK.deliveryType deliveryType
join
config.notificationType notifType
join
notifType.objectType objectType
where
config.id = configEntry.notificationConfigEntryPK.notificationConfig.id
and ( mg.modelId = config.objectId or config.objectId is null )
这是我现在拥有的代码,当然
min(deliveryType.id)
不起作用。未映射mg.modelId和config.objectId之间的关系,deliveryType是一个列表。我不能使用不同的原因我需要能够通过deliveryType订购(这没有任何意义,但我还是需要它)和modelGroupName。
答案 0 :(得分:1)
select config.id, mg.modelGroupName, deliveryType.id from NotificationConfig config, NotificationConfigEntry configEntry, SettlementModelGroup mg join configEntry.notificationConfigEntryPK.user user join configEntry.notificationConfigEntryPK.deliveryType deliveryType with deliveryType.id = (select min(id) from configEntry.notificationConfigEntryPK.deliveryType) ...
