hi guys, i am trying to write a simple utility to do the following: SELECT a bunch of lines from a remote database and INSERT into a local one. i seem to be running into some problems with the following relevant code sections: 
    while ( my (@log_entry) = $xlh->fetchrow_array ) {
           push(@log_entry, undef, "$_") ;
           $mlh->execute(@log_entry) ;
           last if $mch->err ;
    }
sub get_log() {
    my $dbh = shift ;
    my $table = "log" ;
    my $field = join(',',@log_fields[0..6]) ;
    my $sth = $dbh->prepare( qq{ SELECT $field
                                 FROM $table
                                 LIMIT 25 } )
              or db_err("Can't prepare statement: $DBI::errstr") ;
    $sth->execute
          or db_err("Can't execute statement: $DBI::errstr") ;
    return($sth) ;
}
sub put_log() {
    my $dbh = shift ;
    my $table = "log" ;
    my @field = @_ ;
    my ( $nph, $value_ph ) = "$#field"  ;
    my $field = join(',',@field) ;
    while ( $nph-- > -1 ) {
          $value_ph .= '? ' ;
    } ;
    my $sth = $dbh->prepare( qq{ INSERT INTO $table
                                 ($field)
                                 VALUES ( $value_ph ) } )
              or db_err("Can't prepare statement: $DBI::errstr") ;
    return($sth) ;
}
