求证：hql多条件from时丢掉参数

求证：hql多条件from时丢失参数？
最近做一个项目，用from对对象进行查询，结果查出重复数据（composite-id，但是key是正确地override了equals和hashCode）。

让hibernate输出生成的native sql发现

select performscr0_.p_code as p1_26_, performscr0_.sheet_no as sheet2_26_, performscr0_.relat_no as relat3_26_, performscr0_.kind as kind26_, performscr0_.script as script26_, performscr0_.start_day as start6_26_, performscr0_.end_day as end7_26_ from perform_script performscr0_ where performscr0_.p_code='123456' and performscr0_.sheet_no='123456' and [b]performscr0_.kind='pc' [/b]and (performscr0_.start_day is null or performscr0_.start_day='' or performscr0_.start_day<='20070122') and (performscr0_.end_day is null or performscr0_.end_day='' or performscr0_.end_day>='20070122')

条件又出来了。

估计是hibernate的bug。
除非hibernate输出的sql有长度限制。

有碰到同样问题的xdjm没？ 1 楼 抛出异常的爱 2007-01-22   没事用那么多个括号干什么？也没有or都是and需要么？
   1. from PerformScript where  key.pcd='123456'
and key.interviewSheetNo='123456' 
and ( startDay=null or startDay='' or startDay<='20070122')
and ( endDay=null  or endDay='' or endDay>='20070122' ))
and kind='pc'  order by key.relatNo   2 楼 tomgreenintel 2007-01-23   sql问题
