HQL在2个映射表之间联接并以dto类型返回

分类：编程问答

如何解决HQL在2个映射表之间联接并以dto类型返回

我试图从2个映射表中获取数据并以DTO类型返回它们。使用SQL Server数据库，执行HQL查询后，出现以下错误：

花费大量时间尝试查找错误。有人可以帮我解决这个问题吗？

注意：由于其他API正常工作，因此表已正确映射。因此不在这里粘贴

查询： 

select new com.hcl.chks.dto.PendingRecordsDTO(c.id,c.clientName,a.accountType,a.branchNumber,a.regionNumber,a.updatedBy,a.status,a.remarks,a.statusComment) 
from AddressDetailsTransaction a,AccountInfo c 
where version =
(select MAX(version) 
from AddressDetailsTransaction b 
where a.accountNumber = b.accountNumber and 
a.accountType = b.accountType and(a.branchNumber = b.branchNumber OR a.regionNumber = b.regionNumber)) 
and a.accountNumber = c.id**

例外：

解决方法

尝试一下

select new com.hcl.chks.dto.PendingRecordsDTO(c.id,c.clientName,a.accountType,a.branchNumber,a.regionNumber,a.updatedBy,a.status,a.remarks,a.statusComment) 
from AddressDetailsTransaction a 
inner join AccountInfo c 
on a.accountNumber = c.id 
where a.version = (select max(version) from AddressDetailsTransaction)

UPD：如果您需要向子查询中添加一些where条件，这是一种简单的解决方案：

select new com.hcl.chks.dto.PendingRecordsDTO(c.id,a.statusComment) 
from AddressDetailsTransaction a 
inner join AccountInfo c 
on a.accountNumber = c.id 
where a.version = (
   select max(adt.version) 
   from AddressDetailsTransaction adt 
   inner join AccountInfo ai 
   on adt.accountNumber = ai.id
   -- and here comes your where clauses,for instance:
   where ai.clientName = 'John' and adt.branchNumber = 30012)
