In what way?

You can't do that.  execute is part of the DBI package, so you can't
just call it as if it were declared in your own program.  The way I said
is the standard way to do it, so what goes wrong with that?

From "man 3 DBI":

      The typical method call sequence for a "SELECT" statement is:

        prepare,
         execute, fetch, fetch, ...
         execute, fetch, fetch, ...
         execute, fetch, fetch, ...

      for example:

        $sth = $dbh->prepare("SELECT foo, bar FROM table WHERE baz=?");

        $sth->execute( $baz );

        while ( @row = $sth->fetchrow_array ) {
         print "@row\n";
        }
