I posted a snippet a while ago that shows one method of generating an SQL INSERT statement from an anonymous hash and a table name, which is about as simple as you can get. Plus it does clever things to produce placeholdered statements and batched commits.

It really is a funky piece of code that serves me well. OTOH it only works well in a limited domain, that is, it is not the ideal solution when you are inserting different columns sets at different points in the program (as it must generate a fresh prepared statement for each call and it's up to you to remember to tell it to do so).

So I think it would be hard to come up with something that satisfies the general case.

Plus, my main aim was to minimise characters. Not in a golf TM sense, but I didn't want to have to dick around with too many braces, parens or other syntactic fluff.

An example call looks like this:

    insert 'aglrelvalue', {
        att_value    => $id_mission,
        attribute_id => B0,
        client       => DEFCLIENT,
        last_update  => $mis_update,
        percentage   => 100.00,
        rel_attr_id  => YC,
        rel_value    => $regvp,
        user_id      => USER,
    };
