查询使用的hql:

Select
 C02.z0005,
 C02.a0004,
 C02.a0007code.codename,
 C02.z0002code.codename,
 C02.z0006
  from QuData02 C02
   Where (C02.z0002code.codeid like '41%' or C02.z0005 like '%王%') and C02.z0006 = '2006-01' order by C02.a0004 Desc

输出的sql语句:

select
 qudata02x0_.Z0005 as col_0_0_,
  qudata02x0_.A0004 as col_1_0_,
   qucodeitem2_.CODENAME as col_2_0_,
    qucoderegi1_.CODENAME as col_3_0_,
     qudata02x0_.Z0006 as col_4_0_
      from
       data_02 qudata02x0_,
        CODE_REGION qucoderegi1_,
         CODE_ITEM1 qucodeitem2_ 
         where
          qudata02x0_.A0007=qucodeitem2_.ID
           and
            (((qucoderegi1_.CODEID1 like '41%'  and qudata02x0_.Z0002=qucoderegi1_.ID)or(qudata02x0_.Z0005 like '%王%' ))and(qudata02x0_.Z0006='2006-01' ))
             order by  qudata02x0_.A0004 Desc

希望的输出结果:

select
 qudata02x0_.Z0005 as col_0_0_,
  qudata02x0_.A0004 as col_1_0_,
   qucodeitem2_.CODENAME as col_2_0_,
    qucoderegi1_.CODENAME as col_3_0_,
     qudata02x0_.Z0006 as col_4_0_
      from
       data_02 qudata02x0_,
        CODE_REGION qucoderegi1_,
         CODE_ITEM1 qucodeitem2_ 
         where
         qudata02x0_.Z0002=qucoderegi1_.ID and 
          qudata02x0_.A0007=qucodeitem2_.ID
           and
            (((qucoderegi1_.CODEID1 like '41%')or(qudata02x0_.Z0005 like '%王%' ))and(qudata02x0_.Z0006='2006-01' ))
             order by  qudata02x0_.A0004 Desc  

注意输出结果中qudata02x0_.Z0002=qucoderegi1_.ID的位置的不同.

变换成下面的形式的Hql
select * from A a1,AItem item1,AItem2 item2
where a1.id = item1.aId
and a1.id = item2.aId
and item1.name = 'xx'

谢谢!
这样的确可以查出正确的结果,但我还是觉得这应该是hibernate的一个bug
