Question

我得到了这个hibernate异常：

 org.hibernate.QueryException: , expected in SELECT [select tc.id as
 id, tc.terminalServerPort.id as terminalServerPortId,
 tc.terminalServerPort.terminalServer.name as terminalServerName,
 tc.terminalServerPort.terminalServer.ipConfig.ipAddress as
 terminalServerIpAddress, tc.terminalServerPort.portNumber as
 terminalServerPort from
 com.windriver.dsm.labmanagement.data.TargetConsole tc where
 tc.target.id = :targetId order by id asc]

有什么想法吗？谢谢！

Answer 1

Even when I narrow the HQL to the minimum I still get that exception - , expected in SELECT [select tc.id as id from com.windriver.dsm.labmanagement.data.TargetConsole as tc]

你不应该这样写吗？

[select tc.id as id from com.windriver.dsm.labmanagement.data.TargetConsole tc]

为表格提供别名时，为什么要写as？

Answer 2

我找到了解决方案。

显然我正在使用的hibernate版本（hibernate 3）不允许为关联实体分配别名。当我删除这些别名时 - 查询有效。

这是正确的代码：

select tc.id, tc.terminalServerPort.id, 
tc.terminalServerPort.terminalServer.name, 
tc.terminalServerPort.terminalServer.IPConfig.IPAddress, 
tc.terminalServerPort.portNumber 
from TargetConsole tc where tc.target.id = :targetId order by id asc

感谢帮助人员！

Answer 3

您需要为正在使用的sessionFactory配置hibernate转换程序属性。

hibernate.query.factory_class = org.hibernate.hql.ast.ASTQueryTranslatorFactory

这个HQL有什么问题？丢失的逗号在哪里？
