Joining fixed-length CHAR field with VARCHAR field -------------------------------------------------- Key: HHH-5354 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5354 Project: Hibernate Core Issue Type: Bug Components: query-criteria Affects Versions: 3.5.3 Environment: Windows XP, JDK 1.6.0_07, Hibernate 3, Oracle 10g Reporter: Will Sumekar Attachments: OracleCHAR.java I join 2 tables on join condition: table1.col1=table2.col2 col1 is NOT table1's PK, col2 is table1's PK col1's type is CHAR(20), col2's type is VARCHAR(40) I use Hibernate's Criteria API and it doesn't recognise the join condition and gives me 0 row. I've trimmed the padding spaces by extending UserType but it doesn't work. Seems that it only works for retrieving a CHAR field, not joining it to another field. Code: Criteria pq = session.createCriteria(Devices.class).createAlias("PrisProduct", "pp"); pq.add(Restrictions.eq(field, value.trim())); Collection pc = pq.list(); The Devices.hbm.xml excerpt: <property name="dieCode" type="com.st.wma.datalayer.hibernate.util.OracleCHAR"> <column name="DIE_CODE" length="20" not-null="true" unique="true" /> </property> <many-to-one name="PrisProduct" class="com.st.wma.datalayer.hibernate.model.PrisProduct" column="DIE_CODE" not-null="true" insert="false" update="false"> </many-to-one> The PrisProduct.hbm.xml excerpt: <set name="devices" table="DEVICES"> <key column="CAM_PRODUCT"/> <one-to-many class="com.st.wma.datalayer.hibernate.model.Devices"/> </set> OracleCHAR code is attached. It's not in my capacity to change the DB schema so I can't change the CHAR to VARCHAR. environment: Windows XP, JDK 1.6.0_07, Hibernate 3, Oracle 10g Thanks! -- 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
