"selectrow_arrayref"
             $ary_ref = $dbh->selectrow_arrayref($statement);
             $ary_ref = $dbh->selectrow_arrayref($statement, \%attr);
             $ary_ref = $dbh->selectrow_arrayref($statement, \%attr, @bind_values);
           This utility method combines "prepare", "execute" and
           "fetchrow_arrayref" into a single call. It returns the first row of
           data from the statement.  The $statement parameter can be a previ-
           ously prepared statement handle, in which case the "prepare" is
           skipped.
                                                                                
           If any method fails, and "RaiseError" is not set, "selectrow_array"
           will return undef.
