Salutations sooth bearers,

I have a problem, which I'm nearly certain is one of oversight, but I'm a perl novice and apparently going blind so I'd really appreciate some quick advice.

The setup involves modularised dbi routines to delete a row from MySQL. I've managed to work (read: blunt trauma) my head around problems I had with all other types of SQL calls and dereferencing results, but I feel like DBI.pm has some abtuse, unspoken rule used to force us into the celebate life.

Anyway, the (edited) code: 

sub remove {
    ( my @dat = @_ ) =~ /^\d+$/;
    my $statement = qq~DELETE FROM `gates-post` WHERE id = "$dat[1]"~;
    get( "affected" );
    return( undef ) unless( $rows > 0 );

sub get {
    my $opt = shift;
    ( $rows, @rtn ) = '';
    $dbh = DBI->connect( gates->url, gates->accessName, gates->passs, 
+{    AutoCommit => 1, RaiseError => 1 }) || die "DB connect failed: "
+ . $dbh->errstr;
.
.
.
    if ( $opt eq "affected" ) {
        $rows = $dbh->do( $statement ) or die "DB operation failed to 
+affect: " . $dbh->errstr;
        return;
    }

The problems:
Basically, nothing is deleted. However, I know that the statement is formatted properly (and will delete the right row if I stick it through phpMyAdmin for instance); I know that $rows (global var) is returned and has value 1; I'm also sure that the right method 'do' is called. I've tried the extended version of do but since it works for the other calls to it I don't understand why it pretends to succeed for DELETE statements.

I can't get the local 'ward' out of the corner of my eye, so any help would be much appreciated (as would any unrelated 'criticism', of course).

Cheers.
