> I'm trying to create an alias to apply a filter on a composite primary-key association, but I'm getting an invalid SQL generated by the ctiteria api: in the SQL there is the filter applied in the where, but the join for the alias is missing in the from.
> Here is a sample of the problem:
> Mappings (I stripped non relevant info):
> TableOne.hbm.xml
> <hibernate-mapping default-cascade="none">
>     <class name="TableOne" table="TABLE_ONE" dynamic-insert="false" dynamic-update="false">
>         <id name="idTableOne" type="java.lang.Long" unsaved-value="null">
>             <column name="ID_CONTRATTO"/>
>             <generator class="sequence">
>                 <param name="sequence">S_TABLE_ONE</param>
>             </generator>
>         </id>
>         <set name="tableOneToTableTwo" order-by="ID_TABLE_ONE" lazy="true" fetch="select" inverse="true" cascade="none">
>             <key>
>                 <column name="ID_TABLE_ONE"/>
>             </key>
>             <one-to-many class="TableOneToTableTwo"/>
>         </set>
>     </class>
> </hibernate-mapping>
> TableOneToTableTwo.hbm.xml
> <hibernate-mapping default-cascade="none">
>     <class name="TableOneToTableTwo" table="TABLE_ONE_TO_TABLE_TWO" dynamic-insert="false" dynamic-update="false">
>         <composite-id name="tableOneToTableTwoPk" class="TableOneToTableTwoPK">
>             <key-many-to-one name="tableOne" class="TableOne" >
>                 <column name="ID_TABLE_ONE"/>
>             </key-many-to-one>
>             <key-many-to-one name="tabelTwo" class="TabelTwo" >
>                 <column name="ID_TABLE_TWO"/>
>             </key-many-to-one>
>         </composite-id>
>     </class>
> </hibernate-mapping>
> TabelTwo.hbm.xml
> <hibernate-mapping default-cascade="none">
>     <class name="TabelTwo" table="TABLE_TWO" dynamic-insert="false" dynamic-update="false">
>         <id name="idTableTwo" type="java.lang.Long" unsaved-value="null">
>             <column name="ID_TABLE_TWO"/>
>             <generator class="sequence">
>                 <param name="sequence">S_TABLE_TWO</param>
>             </generator>
>         </id>
>         <property name="codTabelTwo" type="java.lang.String">
>             <column name="COD_TABLE_TWO" not-null="true" unique="false"/>
>         </property>
>     </class>
> </hibernate-mapping>
> Code:
> Criteria hibCrit = getSession().createCriteria(TableOne.class);
> hibCrit.createAlias("tableOneToTableTwo", "tableOneToTableTwo");
> hibCrit.createAlias("tableOneToTableTwo.tableOneToTableTwoPk.tabelTwo", "tabelTwo");
> hibCrit.add(Restrictions.eq("tabelTwo.codTabelTwo", "AAA"));
> hibCrit.list();
> Generated SQL using Oracle10G dialect (I stripped columns in select):
> SELECT [...]
>   FROM TABLE_ONE this_ 
>          INNER JOIN TABLE_ONE_TO_TABLE_TWO tabelTwoco1_ ON this_.ID_TABLE_ONE = tabelTwoco1_.ID_TABLE_ONE
>  WHERE tabelTwo2_.COD_TABLE_TWO = ?
> The "tabelTwo2_" should be the sql alias for criteria alias "tabelTwo", but the table and the join are missing in the from...
> I also tried using createCriteria:
> Criteria hibCrit = getSession().createCriteria(TableOne.class);
> hibCrit.createAlias("tableOneToTableTwo", "tableOneToTableTwo");
> Criteria tableTwoCrit = hibCrit.createCriteria("tableOneToTableTwo.tableOneToTableTwoPk.tabelTwo", "tabelTwo");
> tableTwoCrit.add(Restrictions.eq("tabelTwo.codTabelTwo", "AAA"));
> hibCrit.list();
> But i get the same sql query.
> Also upgrading Hibernate result in the same behavior.
