休眠::意外的標記：FOR

我有這個疑問在休眠中使用與Java：休眠::意外的標記：FOR

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);

但我得到一個錯誤：

unexpected token: FOR 
    at org.hibernate.hql.internal.antlr.HqlBaseParser.atom(HqlBaseParser.java:3473) 
    at org.hibernate.hql.internal.antlr.HqlBaseParser.unaryExpression(HqlBaseParser.java:3168)

    at org.hibernate.hql.internal.antlr.HqlBaseParser.logicalExpression(HqlBaseParser.java:1786)

爲什麼？

查詢的問題部分是：

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

FOR XML PATH是MSSQL 2005 feature在Hibernate中缺席。 HQL不是SQL的超集，當然它不能訪問數據庫特定的功能。

對於這種用例，您應該使用native query，因爲它允許您通過Hibernate API使用SQL直接查詢數據庫。
