CMR PROBLEM. ORA-00904 ERROR !
Hi,
i have an ORA-00904 error in the SQL statement corresponding to the EJB QL query.
I only have this problem when i use the relationship between my two entities.
this is the definition of the relationship in the ejb-jar
<ejb-relation>
<ejb-relation-name>Equip_type - Register</ejb-relation-name>
<ejb-relationship-role>
<ejb-relationship-role-name>Equip_type may have many Register</ejb-relationship-role-name>
One
<relationship-role-source>
<ejb-name>Equip_type</ejb-name>
</relationship-role-source>
<cmr-field>
<cmr-field-name>registers</cmr-field-name>
<cmr-field-type>java.util.Set</cmr-field-type>
</cmr-field>
</ejb-relationship-role>
<ejb-relationship-role>
<ejb-relationship-role-name>Register may have one Equip_type</ejb-relationship-role-name>
Many
<relationship-role-source>
<ejb-name>Register</ejb-name>
</relationship-role-source>
<cmr-field>
<cmr-field-name>equip_typ</cmr-field-name>
</cmr-field>
</ejb-relationship-role>
</ejb-relation>
my RegisterBean.java :
...
public abstract Equip_typeLocal getEquip_Typ();
public abstract void setEquip_Typ(Equip_typeLocal equip_typ);
my Equip_typeBean.java :
...
public abstract java.util.Set getRegisters();
public abstract void setRegisters(java.util.Set registers);
the EJB QL :
SELECT OBJECT(a) FROM Register as a
the error :
