Question

我有这个查询用于hibernate with java：

String hql = "select part.ID,part.PartNumber,part.Name,parttype.Name,partkind.Name,
                      partdevice.Name,part.Count,STUFF((SELECT ', ' + cabinet.Name FROM Cabinet as 
                      cabinet,Part_Cabinet as part_cabinet WHERE part.ID=part_cabinet.PaId and cabinet.ID =
                      part_cabinet.CabId FOR XML PATH('')),  1, 1, ''),part.Descript from Part as part,
                      PartDevice as partdevice,PartKind as partkind,PartType as parttype Where
                      part.Kind=partkind.ID and part.Type=parttype.ID and part.Device=partdevice.ID";
Query _q = session.createQuery(hql);

但是我收到了一个错误：

为什么？

Answer 1

查询中有问题的部分是：

WHERE part.ID=part_cabinet.PaId
AND cabinet.ID = part_cabinet.CabId
FOR XML PATH('')

FOR XML PATH是Hibernate中缺少的MSSQL 2005 feature。 HQL不是SQL的超集，当然也无法访问数据库特定的功能。

您可能应该将native query用于此用例，因为它允许您通过Hibernate API直接使用SQL查询数据库。
