I have a feeling I'm doing something very wrong, this simple query fails to parse:

Code:

select
    b2
from
    Benefit b1,
    Benefit b2
where
    b1.benefitType.code = 'H001' and
    b2 = b1

The error message is "path expression ends in a composite value: benefit1_". My mapping for Benefit is:

Code:

<class name="com.ff.model.life400.core.Benefit" table="LIFE400_VW_BENEFIT">
   
      <composite-id>
         <key-property name="policyNumber" column="CHDRNUM"/>
         <key-property name="lifeKey" column="LIFE"/>
         <key-property name="coverage" column="COVERAGE"/>
         <key-property name="rider" column="RIDER"/>
         <key-property name="jointLifeKey" column="JLIFE"/>
      </composite-id>

      <property name="sumInsured" column="SUMINS"/>
      
      <many-to-one name="riskStatus" column="STATCODE"/>
      
      <many-to-one name="benefitType" column="CRTABLE"/>

   </class>

I tried using a component composite ID and got the same problem. Am I going mad or is this simply not supported?

Thanks

Niall

You can actually, the code above would work fine if Benefit had an atomic PK.

I have tried all of the comparisons below but none parse correctly if the types have a composite key.

b1 = b2
b1.id = b2.id
b1.key = b2.key
b1.key.id = b2.key.id
