hibernate不支持-1做查询条件吗，强人解答

hbm.xml
<property name="state" type="short">
            <column name="state" not-null="true">
                <comment>-1:保密,0:公开&amp;未兑现,1:公开&amp;申请中,3:公开&amp;已兑现</comment>
            </column>
        </property>
应其它原因不使用hibernate的关联关系和hql，而是直接使用sql正常的语句:
Hibernate: select a.id,a.passport,a.realname,c.name from tb_spreader as a inner join tb_billbranch as b on a.id=b.spreader_id inner join tb_billtrunk as c on c.id=b.billT_id where b.state=0 
查询出的记录条数：1====上面的语句和下面的语句一字之差b.state=0 /b.state=-1,却是两种结果,我在mysql中执行都能成功，难道是-1出错，晕============出错的语句
Hibernate: select a.id,a.passport,a.realname,c.name from tb_spreader as a inner join tb_billbranch as b on a.id=b.spreader_id inner join tb_billtrunk as c on c.id=b.billT_id where b.state=-1
