Question

我在HQL中用Hibernate编写了以下查询。

=============================================== =========================

select new map(ret.retailerDesc as ret_name, ret.id.retailerId as ret_id,
               ret.id.serviceId as service_id,  

(select count(distinct i.inspectionId) as inspections from Inspection i 
inner join i.clgCodeStatus c 
inner join c.retailerOrderses r  
inner join r.cusRetailer cr 
inner join i.inspectionMission m  where ret.id = cr.id  ) as inspections ,

(select count(distinct i.inspectionId) as inspections   from Inspection i 
inner join i.clgCodeStatus c 
inner join c.retailerOrderses r 
inner join r.cusRetailer cr 
inner join i.inspectionMission m 
where ret.id = cr.id  and i.inspectionResult = '1'  ) as match,

(select count(distinct i.inspectionId) as inspections   from Inspection i 
inner join i.clgCodeStatus c 
inner join c.retailerOrderses r 
inner join r.cusRetailer cr 
inner join i.inspectionMission m 
where ret.id = cr.id  and i.inspectionResult = '0'  ) as mismatch  )

from CusRetailer ret  order by inspections desc

=============================================== ========================

当执行上述查询时，会出现以下错误：

ERROR: column "inspections" does not exist

“检查desc”的命令给出了这个错误。如果我删除它工作正常。

有谁可以帮我解决这个问题？

感谢。

Answer 1

可能需要重复inspections

的表达式

...from CusRetailer ret order by count(distinct i.inspectionId)

可能HQL不支持order by子句中的表达式，您可能需要使用n SQL查询。

Answer 2

我在上面的查询中使用“按col_1_0_命令”解决了它...因为hibernate创建了名为col_0_0_，col_1_0_，col_2_0_等的列...所以如果您只需要知道列的顺序并将其添加到订单中相应地..

感谢。
