Criteria.createAlias not working for key-many-to-one associations of a composite-id ----------------------------------------------------------------------------------- Key: HHH-4591 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4591 Project: Hibernate Core Issue Type: Bug Components: query-criteria Affects Versions: 3.3.2, 3.2.7, 3.2.6 Environment: Hibernate 3.2.6.ga, 3.2.7.ga, 3.3.2.ga Database: Oragle10g Reporter: Luka 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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
