if statement problem using mysql

[CreationP]

I'm using a table named 'options' which has 1 field with the name 'log' and one record which can be only 1 or 0. Default value is 1. I want to enable or disable logging to my progra, using the following code:

 if ($choise ==6){

    $sql1 = "select * from scanner.options";
    $sth1 = $dbh ->prepare($sql1);
    $sth1->execute or die "SQL Error: $DBI::errstr\n";
    while (@option - $sth1 ->fetchrow_array()){
    $log = $option[0];
    }
    
    if ($log == 1){
    
        print "Logs = 1";
        print "\n\nWould you like to disable logging? (press 1 for yes
+ or anything else for no): ";
        my $o_log= <STDIN>;
    
        if ($o_log == 1){
    
            my $sql = "UPDATE options SET log=0 WHERE log=1";
            $sth = $dbh->prepare($sql);
            $sth->execute
                or die "SQL Error: $DBI::errstr\n";
        }
    }
    else{
        
        print "Logs = 0";
        print "\n\nWould you like to enable logging? (Press 1 for yes 
+or anything else for no): ";
        my $o_log= <STDIN>;
        
        if ($o_log == 1){
        
        
        my $sql = "UPDATE options SET log=1 WHERE log=0";
        $sth = $dbh->prepare($sql);
        $sth->execute
            or die "SQL Error: $DBI::errstr\n";
        }
    }
}

Using this code I cannot get the program to go into the first if function ($log == 1). I also tried with if ($option[0] == 1) and it still does not work. My value in the mysql table is 1. Why is it not working and how can I make it work? Thank your for your time.
