Invalid SQL generated for mapping with property-ref
---------------------------------------------------

         Key: HHH-1819
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1819
     Project: Hibernate3
        Type: Bug

  Components: query-hql  
    Versions: 3.1.3    
 Environment: Oracle 8.1.7
    Reporter: Jakub Mendys
    Priority: Critical


Consider mappings:
	<class name="MedDRATerm" table="MBROW_MEDDRA_TERMS" mutable="false"
		batch-size="50">
		<cache usage="read-only" region="dictionary" />
		<id name="medDRATermId" type="long" column="TERM_ID">
			<generator class="assigned" />
		</id>
		<map name="termNames" table="MBROW_TERM_NAMES" lazy="true"
			batch-size="50">
			<cache usage="read-only" region="dictionary" />
			<key column="MEDDRA_CODE" property-ref="medDRACode" />
			<index column="LANGUAGE_ID"
				type="com.roche.dss.meddra.dao.type.LanguageType" />
			<element column="NAME" type="string" />
		</map>
		<property name="medDRACode" column="MEDDRA_CODE"
			type="com.roche.dss.meddra.dao.type.MedDRACodeType" />
	</class>
	<class name="MedDRATermInstance" table="MBROW_MEDDRA_TREES"
		mutable="false">
		<cache usage="read-only" region="dictionary" />
		<id name="medDRATermInstanceId" type="long" column="NODE_ID">
			<generator class="assigned" />
		</id>
		<many-to-one name="medDRATerm" class="MedDRATerm"
			column="TERM_ID" fetch="join" not-null="true" insert="false"
			update="false" />
	</class>

and a HQL query:

from MedDRATermInstance i where i.medDRATermInstanceId is not null and i.medDRATerm.termNames[1] like 'headache'

Having this Hibernate will generate following SQL:

SELECT ...
  FROM orcl_gthes.mbrow_meddra_trees meddraterm0_,
       orcl_gthes.mbrow_term_names termnames2_
 WHERE meddraterm1_.meddra_code = termnames2_.meddra_code
   AND termnames2_.language_id = 1
   AND meddraterm0_.term_id = meddraterm1_.term_id
   AND (termnames2_.NAME LIKE 'headache')

Please note that WHERE clause refers to alias meddraterm1_ which is not mentioned in FROM section!!!!
