this is a bit of a theory question. (laugh if you will, but remember my degree is in philosophy and didn't take math from 8th grade on :)

i have three things A, B and C. They will be snippets of SQL. A will always be the sart of the string. If B exists, I want to join it to A by ' where ', and if C exits i want to join it to A with ' where ' if B is not there and with ' and ' if it is there. I know i can 

if ( $b and $c ) {
    $string = "$a" . ' where ' . "$b" . ' and ' . "$c";
} elsif ( $b or $c ) {
    if ( $b ) {
        $string = "$a" . ' where ' . "$b";
    } else {
        $string = "$a" . ' where ' . "$c";
    }
}

my gut tells me there's a better way to do this though I don't know how. ideas?
