Hey.
Just guessing here since im not really sure what you want....
So just fill in the blanks from ur DB table.

SELECT {table_column_here} FROM {your_table_name} WHERE {what_you_want}

If you can supply the table details i can help you complete this

Are you using any server side scripting...
Please give some more info

<? 
$cres=mysql_query("SELECT * FROM table  ORDER BY id ");
$ccunt=mysql_num_rows($cres);
	echo "<script language=javascript>\n";
	echo "function getsubcats() {\n";
		echo "var d=document.frmaddpro;\n";
		echo "if(d.selcategory.value==0) {\n";
			echo "d.selsubcat.options.length = 0;\n";
			echo "d.selsubcat.options[0]=new Option(\"Select Subcategory\",\"\")\n";
		echo "}\n";
	while($row_cat=mysql_fetch_array($cres,MYSQL_BOTH)){
		echo "if(d.selcategory.value==".$row_cat['id'].") {\n";
				echo "d.selsubcat.length=0;\n";
				$sub_res=mysql_query("SELECT * FROM table WHERE codeid='".$row_cat['id']."'");  
				$i=1;
				echo "d.selsubcat.options[0]=new Option(\"Select Subcategory \",\"\")\n";
				while($sub_row=mysql_fetch_array($sub_res,MYSQL_BOTH)){
					echo "d.selsubcat .options[".$i."]=new Option('".$sub_row['name']."','".$sub_row['c_id']."');\n";
					$i=$i+1;
				}   
		echo "}\n";
	}  
	echo "}</script>\n"; 

?>

$cres=mysql_query("SELECT * FROM table  ORDER BY id ");
$ccunt=mysql_num_rows($cres);
	echo "<script language=javascript>\n";
	echo "function getsubcats() {\n";
		echo "var d=document.frmaddpro;\n";
		echo "if(d.selcategory.value==0) {\n";
			echo "d.selsubcat.options.length = 0;\n";
			echo "d.selsubcat.options[0]=new Option(\"Select Subcategory\",\"\")\n";
		echo "}\n";
	while($row_cat=mysql_fetch_array($cres,MYSQL_BOTH)){
		echo "if(d.selcategory.value==".$row_cat['id'].") {\n";
				echo "d.selsubcat.length=0;\n";
				$sub_res=mysql_query("SELECT * FROM table WHERE codeid='".$row_cat['id']."'");  
				$i=1;
				echo "d.selsubcat.options[0]=new Option(\"Select Subcategory \",\"\")\n";
				while($sub_row=mysql_fetch_array($sub_res,MYSQL_BOTH)){
					echo "d.selsubcat .options[".$i."]=new Option('".$sub_row['name']."','".$sub_row['c_id']."');\n";

Why not use ajax? Its better than having php create the javascript which adds to the page size and load time.
