In fact it seems that it is a driver error. We are using MSSQL server with

Hi,
Is there any possibility, without using QueryBySQL , to create a query join

Thanks a lot.

Hi Thomas.

In my repository I have the following mapping for a collection using m:n

I am no expert and it has been a few months since I used the ODMG API.

Is there a way to construct an OQL query (I am using the OTM, but it
should be the same conceptually as the ODMG api) to query against the
identity of a child persistent object. For example:
class Profile
{
private Group group;
}
class Group
{
}

Hi Armin,
took some time but I was able to build the testcase.
snip :-)
Why not all objects are selected and why without throwing any
exception?
Is there a workaround (instead of making a lot of primary key selects)?

of eager-release,

hi thomas,
this is pretty much normal behaviour !
the first query looks for all persons having a phonenumber like "052*"
and returns these persons. when you do person.getPhones() all phones
belonging to this ONE person are returned, no matter what the number is
(at least one is like "052*").

As shown in the 'Query' documentation if the SqlInLimit property is

Yes, it seems to be. We have had no problems with rollback since.
But I am concerned about using ConnectionFactoryPooledImpl
