Hi,

I've managed to get all of my direct JDBC calls replaced except for one. =
 I can't figure out how to write this particular query using the =
hibernate query language, so I'm not even sure it is possible.  If it's =
not possible then I'll take the time to implement it, however I wanted =
to make sure first.

Below is an example of the resulting SQL that I want to create:

select foo.id, foo.name
from foo
where foo.id in
(
   select foo_attr.id_foo
   from foo_attr
   where (foo_attr.id_attribute =3D 'attribute1' and foo_attr.strvalue =
=3D 'value1')=20
   and id_foo in
   (
       select foo_attr.id_foo
       from foo_attr
       where (foo_attr.id_attribute =3D 'attribute2' and =
foo_attr.strvalue =3D 'value2')=20
    )
)

Basically, there is a parent table ("foo" in my example above) and there =
is list of attributes for a particular foo object (called "foo_attr") in =
my example above.  I want to find all Foo's where it have an attribute =
"attribute1" equal to "value1" and an attribute "attribute2" equal to =
"value2".

So, is this something I will have to implement (and if so, are there =
suggestions on the syntax of the query), or does this already exist?

Thanks,
Jon...
