order by with placeholders in DBIx::Class

Question

What's the proper way to generate an order by like ORDER BY myfunction(col, ?, ?) DESC with bind values in DBIx::Class?

Currently I use literal SQL for this, but that's not optimal for several reasons.

$rs->search(undef, { order_by => \"myfunction(col, $v1, $v2) DESC" });

Answer 1

I did manage to get DBIx::Class to generate the correct ORDER BY. Here is the code:

$rs->search(undef, {
    order_by => \[
        'myfunction(mycol, ?, ?) DESC', map [dummy => $_], $v1, $v2
    ]
});
