가 TemporaryAccessOpenCommand 및 TemporaryAccessCloseCommand 모두가 기본 클래스 명령에서 상속 다음 매핑 파일을 고려NHibernate에 쿼리 문제
<class name="Command" table="xxx_Commands" lazy="false">
<id name="Id" type="Int32" unsaved-value="0">
<generator class="identity"/>
</id>
<property name="BeginDate" />
<property name="EndDate" />
<component name="Result" class="CommandResult">
<property name="Status" column="ResultStatus"/>
<property name="Details" column="ResultDetails" />
</component>
<many-to-one name="Requestor" class="xxx.Domain.SessionInfo, xxx.Domain" column="SessionInfoId" lazy="false" />
<joined-subclass name="xxx.TemporaryAccess.Commands.TemporaryAccessCloseCommand, xxx.TemporaryAccess" table="xxx_Commands_TemporaryAccess_Close">
<key column="CommandId"/>
</joined-subclass>
<joined-subclass name="xxx.TemporaryAccess.Commands.TemporaryAccessOpenCommand, xxx.TemporaryAccess" table="xxx_Commands_TemporaryAccess_Open">
<key column="CommandId"/>
<many-to-one name="EndUser" ...... />
<property name="Reason"/>
<property name="AccessRight"/>
<property name="AccessType"/>
<bag name="CloseAccessCommands" cascade="all" lazy="false">
<key column="OpenCommandId"/>
<one-to-many class="xxx.TemporaryAccess.Commands.TemporaryAccessCloseCommand, xxx.TemporaryAccess"/>
</bag>
</joined-subclass>
무슨이 CloseAccessCommand 성공이없는 모든 OpenAccessCommand를 검색 할 NHibernate에 쿼리를 것입니까?
나는이 시도 :public IList<TemporaryAccessOpenCommand> FindOpenCommandsWithoutSucceededCloseCommand()
{
return this.HibernateTemplate.ExecuteFind<TemporaryAccessOpenCommand>(delegate(ISession session)
{
return session.CreateCriteria(typeof(TemporaryAccessOpenCommand))
.CreateCriteria("CloseAccessCommands")
.Add(Expression.Not(Expression.Eq("Result.Status", CommandStatus.Succeeded)))
.List<TemporaryAccessOpenCommand>();
});
}
을하지만 빈 목록을 반환해야 할 때 그것은 견인 CloseCommand을 (하나 실패 하나가 성공)이있는 OpenAccessCommand를 반환합니다.
