Hi,

I'm struggling working on (inner) join in DBIx::Class.
I looked through the documents but, didn't figure out what to do.

table A (class name is 'ClassA')
---
id
tmp_id
---

table B (class name is 'ClassB')
---
id
info1
info2
info3
---

What I want to do is very simple listed below.

select * from A, B where A.id = B.id and A.tmp_id = 'someid';


In DBIx::Class

    $rs = $schema->resultset('ClassB')->search(
        {
            'A.tmp_id' => 'someid'
        },
        {
            join => [qw/A/],
        }
    );

It doesn't work and i get the following error.

"No such relationship ... "

Do I have to specify the relationship for the normal join ?
Does anybody know what to do to achieve the sql ?

Thanks,

Hiroyuki Yamada
