命名查询Hibernate中的坏语法错误

Question

当我尝试用Java中的hibernate运行这个查询时出错了并抛出一个错误

( 12002 ) Internal Service Error. Exception Message : Bad Sql Grammar Exception occurred [Hibernate operation: could not execute query; bad SQL grammar [SELECT COMDT_COM_STAT, COMDT_COM_REFNO, COMDT_COM_CCY  
            FROM COMDT 
            WHERE COMDT_COM_REFNO = ? 
            AND COMDT_COM_RDN BETWEEN ? AND ? 
            AND COMDT_COM_STAT = ?
            GROUP BY COMDT_COM_STAT, COMDT_COM_REFNO, COMDT_COM_CCY 
            ORDER BY COMDT_COM_REFNO]; nested exception is java.sql.SQLException: Invalid Column Name]

但是当我在PLSQL中使用适当的输入运行相同的查询时，一切都按预期工作。我正在处理这个错误2天但没有出现。

谢谢。
