带子句的 grails HQL

Question

由于我之前的问题没有得到解答，我想再问一次。

高品质

    from Agenda agr 
    inner join agr.agenda a with a.employee.id = :employeeId
    left join agr.employer wgr
    left join wgr.contracts cnt with agr.date >= cnt.validFrom and agr.date < cnt.ValidUntil

我收到了消息

with-clause referenced two different from-clause elements

native SQL

left join contract cnt
    on agr.wgv_id = cnt.wgv_id
       and agr.date >= cnt.validFrom
       and agr.date < cnt.validTill

在上一个问题中，建议是使用 HQL 和 'with' 子句。这可能是一种方式吗？建议？

Answer 1

{替换}

如果您希望捕获空记录，则只需要左连接，否则只需使用连接

from Agenda agr
    inner join agr.agenda a with a.employee.id = :employeeId
    left join agr.employer wgr
    left join wgr.contracts cnt
where agr.date >= :start
    and agr.date <= :end
    and ((agr.date >= cnt.validFrom and agr.date < cnt.validTill) or agr.employer is Null)
