Name and version of the database you are using:
Oracle9i

Hi all! I'm using hibernate-tools3-alpha1 with eclipse3.1m6. In hibernate console perspective I have created configuration and trying to perform some queries against my datasource.
Operatio and Specific are in one-to-many biderectional relationship(one operatio to many specific).
queries like
Code:
from Operatio as op where op.cod=....
and like
Code:
select sp.operatio from Specific as sp where sp.cod=...
work fine. But when I'm trying to execute query like this one
Code:
select op.specific from Operatio as op where op.cod=...
exception occured[/code]

I think the error message is telling you exactly what it should. You need to pick whether you want to select the elements of the set, or the indices (keys) of the set.

The former would be:
select elements(op.specific) from ...

The latter would be:
select indices(op.specific) from ...

Makes sense? Nothing wrong with the mapping, that's just HQL syntax.

Sorry, I should add - you can't use the indices operator unless the collection you're querying has an index. So in your case, I believe the only thing you can do is elements().

It worked perfectly great.
If your <many-to-one is of type List, you might need to include
<list-index column="indexcolumn">

If your table doesn't have any index column, we can as well define the collection as set and use elements() in HQL.

Thanks guys, I had the same problem and this posting helped me.
