I have put together a few routines to handle sessions on a web-driven script which uses DBI to access MySQL. I've encountered a problem that I can't seem to get by: I prepare a statement to delete a row in a database if the username matches, when I use the mysql client, the SQL statement works fine, but through the script it just doesn't seem to do it. Reading through some of the nodes brought me to the quoting problems some SQL servers and DBI have to overcome, while aware of this I've never paid too much attention since I bind most if not all of my variables. Here's a bit of code:

sub del_session {

    my $user = $_;
    my $dbh = DB_Methods::db_connect();
    my $sth = $dbh->prepare("DELETE FROM session WHERE     user_name L
+IKE ?");
    $sth->bind_param(1, $user);
    $sth->{ChopBlanks} = 1;
    unless ($sth->execute()) {die $dbh->errstr();}
    $sth->finish();
    $dbh->disconnect();
}

While I don't see any problems with this code, the end result from this call doesn't produce any sql errors so I can assume that the statement has been executed and the row(s) deleted. But when I check the table ... it still contains the row that was to be removed. Can anyone enlighten me as to what I'm missing here (running out of options).
