How to change alphabetic and numeric pager?

How can I change this code so that it works as follows in case it puts the initial letters of each item added in $ aInitials in the case it clicks it filters listing all the items with that initial letter with all numbers, characters and symbols it too inserts them individually by making them appear in the list of links in initial $ I would like a way to make a single link to identify all items with numbers and characters then if it was clicked it lists all items not started by alphabet letters.

How can I do this?

<table width='400' align="center">
<tr>
<?
mysql_connect("localhost","usuariobanco", "senhabanco");
mysql_select_db("bancodedados");

$db = "tabela";
$coluna = "coluna";

$Consulta = mysql_query(" SELECT UPPER(LEFT($coluna, 1)) inicial FROM $db GROUP BY inicial  ORDER BY inicial") or die (mysql_error());
while ($rs = mysql_fetch_array($Consulta)) {
$aIniciais = $rs["inicial"];
$v = "<font style='font-family: Verdana,Tahoma,Arial,Helvetica,Sans-serif; font-size: xx-small; '>
      <a href='?inicial&ini=$aIniciais'> $aIniciais</a></font>" ;

printf(" <td>| $v</td> ");
}
