> There is a table Person with composite primary key:
> PERSON
> primary key fields:
>   FAMILY
>   NUMBER
> For the Criteria Query like
> 		List<PersonId> ids = new Vector<PersonId>();
> 		ids.add(new PersonId("SLAVA1", 10L));
> 		ids.add(new PersonId("SLAVA2", 20L));
> 		ids.add(new PersonId("SLAVA3", 30L));
> 		List<Person> persons = session.createCriteria(Person.class)
> 			.add(Restrictions.in("id", ids))
> 			.list();
>  the query  is generated
> select this_.FAMILY as FAMILY0_0_, this_.NUMBER as NUMBER0_0_ from PERSON this_ where (this_.FAMILY, this_.NUMBER) in ((?, ?), (?, ?), (?, ?))
> The query is right, but the parameters are bound in wrong order, here is the excerpt from the log:
> 16:21:33,221 DEBUG [SQL] select this_.FAMILY as FAMILY0_0_, this_.NUMBER as NUMBER0_0_ from PERSON this_ where (this_.FAMILY, this_.NUMBER) in ((?, ?), (?, ?), (?, ?))
> Hibernate: select this_.FAMILY as FAMILY0_0_, this_.NUMBER as NUMBER0_0_ from PERSON this_ where (this_.FAMILY, this_.NUMBER) in ((?, ?), (?, ?), (?, ?))
> 16:21:33,221 DEBUG [AbstractBatcher] preparing statement
> 16:21:33,330 DEBUG [StringType] binding 'SLAVA1' to parameter: 1
> 16:21:33,330 DEBUG [StringType] binding 'SLAVA2' to parameter: 2
> 16:21:33,330 DEBUG [StringType] binding 'SLAVA3' to parameter: 3
> 16:21:33,330 DEBUG [LongType] binding '10' to parameter: 4

> I've made an example (attached, standalone eclipse project with all libs) which demonstrates the problem, but you need running oracle somewhere to run it. See also bug report HH-708 which is predecessor of this.
> The problem may lay in org.hibernate.criterion.InExpression::getTypedValues.
> Instead of 
> for ( int i=0; i<types.length; i++ ) { 
> for ( int j=0; j<values.length; j++ ) { 
> Object subval = values[j]==null ? 
> null : 
> actype.getPropertyValues( values[j], EntityMode.POJO )[i]; 
> list.add( new TypedValue( types[i], subval, EntityMode.POJO ) ); 
> } 
> } 
> should be 
> for ( int j=0; j<values.length; j++ ) { 
> for ( int i=0; i<types.length; i++ ) { 
> Object subval = values[j]==null ? 
> null : 
> actype.getPropertyValues( values[j], EntityMode.POJO )[i]; 
> list.add( new TypedValue( types[i], subval, EntityMode.POJO ) ); 
> } 
> } 
> After change have worked for me. But I am not sure whether the syntax of what's going from Restriction.in is database-specific.
