Error on binding values prepared statment in many-to-any relation ----------------------------------------------------------------- Key: HHH-5160 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5160 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5.1, 3.3.2 Environment: Tested on Version 3.3.2 and 3.5.1 on Oracle, PostgreSQL and MySQL Reporter: wof A Collection of Entities is defined as a ManyToAny relation, e.g. @ManyToAny(metaColumn=@Column(name="C_OBJECT_TYPE")) @AnyMetaDef(idType="string", metaType="string", metaValues={ @MetaValue(targetEntity=Entity1.class, value="Entity1"), @MetaValue(targetEntity=Entity2.class, value="Entity2") }) @JoinTable(name="T_OBJECTS", joinColumns=@JoinColumn(name="C_OWNER_ID"), inverseJoinColumns=@JoinColumn(name="C_OBJECT_ID") ) private Set<EntityBase> objects = new HashSet<EntityBase>(); Adding to this set works without problems. Removing all elements from the set (i.e. setting the set to null or zero-sized), too. However, when one or more elements are removed from the set with at least one element remaining, an exception is thrown: org.hibernate.exception.GenericJDBCException: could not delete collection rows with the cause being java.sql.SQLException: Parameter index out of range (3 > number of parameters, which is 2). I have narrowed this problem to this: The mapping table consists of 3 columns, C_OWNER_ID, C_OBJECT_TYPE and C_OBJECT_ID. The generated SQL-statement to delete the rows is as folling: DELETE FROM t_objects WHERE c_owner_id=? AND c_object_id=? However, Hibernate (in org.hibernate.typ.AnyType) tries to bind the actual value for c_object_id with index 3 which causes the exception. I guess Hibernate expects c_object_type to be present in the statement. As workaround we changed nullSafeSet in AnyType to: public void nullSafeSet(PreparedStatement st, Object value, int index, boolean[] settable, SessionImplementor session) throws HibernateException, SQLException { Serializable id; String entityName; if (value==null) { id=null; entityName=null; } else { entityName = session.bestGuessEntityName(value); id = ForeignKeys.getEntityIdentifierIfNotUnsaved(entityName, value, session); } // metaType is assumed to be single-column type // <ORIGINAL CODE> /* if ( settable==null || settable[0] ) { metaType.nullSafeSet(st, entityName, index, session); } if (settable==null) { identifierType.nullSafeSet(st, id, index+1, session); } else { boolean[] idsettable = new boolean[ settable.length-1 ]; System.arraycopy(settable, 1, idsettable, 0, idsettable.length); identifierType.nullSafeSet(st, id, index+1, idsettable, session); } */ // </ORIGINAL CODE> // <PATCHED CODE> if ( settable==null || settable[0] ) { metaType.nullSafeSet(st, entityName, index, session); boolean[] idsettable = new boolean[ settable.length-1 ]; System.arraycopy(settable, 1, idsettable, 0, idsettable.length); identifierType.nullSafeSet(st, id, index+1, idsettable, session); } else if (settable==null) { identifierType.nullSafeSet(st, id, index+1, session); } else { boolean[] idsettable = new boolean[ settable.length-1 ]; System.arraycopy(settable, 1, idsettable, 0, idsettable.length); identifierType.nullSafeSet(st, id, index, idsettable, session); } // </PATCHED CODE> } best regards wof -- 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
