MySQL permutation

Question

I have two tables. One has products and the other has bundles that go with it. I need to figure out the SQL that allows me to find all the combinations in which I can sell

Answer 1

I cannot think of any ingenious way of doing this in mysql, but it is very easy in a scripting language. Here in PHP:

 $item) {
        if ($i & pow(2, $j)) {
            $combo[] = $item;
        }
    }

    echo implode(' + ', $combo) . "\n";
}

prints

Bench
Bench + undershelf
Bench + overshelf
Bench + undershelf + overshelf
Bench + sheels
Bench + undershelf + sheels
Bench + overshelf + sheels
Bench + undershelf + overshelf + sheels
