[Dbix-class] Date not inflating

[Dan Horne]

Hi

Consider the following: A config has many sections. A section has many
process runs. I want to find the latest process run from a config and
section combination:

my $rs =3D $scheduler->EpProcessRun->search(
    {
        'ep_config.config_name' =3D> 'my_config',
        'ep_section.section_name' =3D> 'my_section',
    },
    {
        select =3D> [ { max =3D> 'me.date_created' } ],
        as     =3D> [ 'date_created' ],
        'join'     =3D> {'ep_section' =3D> ['ep_config']},
    }
);

say $rs->first->get_column('date_created');

This works - but the date is text, whereas I was hoping it would be inflated
to a  DateTime object (as they are with regular queries). The generated SQL
is

SELECT MAX(me.date_created)
FROM   ep_process_run me
JOIN   ep_section ep_section
ON     ep_section.section_id =3D me.section_id
JOIN   ep_config ep_config
ON     ep_config.config_id =3D ep_section.config_id
WHERE  ((ep_config.config_name =3D ? AND ep_section.section_name =3D ?))

I also tried

my $rs =3D $scheduler->EpProcessRun->search(
    {
        'ep_config.config_name' =3D> 'my_config',
        'ep_section.section_name' =3D> 'my_section',
    },
    {
        'join'     =3D> {'ep_section' =3D> ['ep_config']},
    }
);

say $rs->get_column('date_created')->max;

The generated SQL is exactly the same, and the date isn't inflated. Am I
doing something wrong, or have I hit a DBIx::Class limitation? I;m on
DBIx:Class v0.08123 on Win32
