Hi,

I am having problem putting together a DBIx::Class query that uses a mysql-function in the where-clause.

Here is my resultset: 

package MyDB::Schema::Result::Queue;
use strict;

use base qw/DBIx::Class::Core/;

__PACKAGE__->table('queue');
__PACKAGE__->add_columns( id => { is_auto_increment => 1},
                         qw/ msg box /);
__PACKAGE__->set_primary_key('id');

1;

[download]
The query I want to (re-)construct is select id, msg, box from queue where is_lock_free(box) order by id limit 1

The best I can get at the moment is 

my $rs = $schema->resultset('Queue');

my $q = $rs->search ({ -bool => "is_free_lock(me.box)" }, { order_by =
+> 'id', rows => 1 })->single;

[download]
Which produces SELECT me.id, me.msg, me.box FROM queue me WHERE ( is_free_lock(me.box) ) ORDER BY id LIMIT 1 which actually works but of course is obtained by cheating because I supplied the me.box argument to is_lock_free by hand...

How can I do this without cheating?

Many thanks!
