Php code about sql query

Question

for example:
create table testtable (
order_number number(4),
item_id number(4),
quantity number(8),
item_desc varchar2(16)
insert into testtable values (1001,1,10,'apple');
insert into testtable values (1001,2,20,'banana');
insert into testtable values (1002,2,50,'banana');
insert into testtable values (1002,1,30,'apple');
insert into testtable values (1003,3,60,'orange');
insert into testtable values (1004,3,50,'orange');
commit;
Table Test DATA
order_number item_id quantity item_desc
1001 1 10 apple
1001 2 20 banana
1002 2 50 banana
1002 1 30 apple
1003 3 60 orange
1004 3 50 orange
i want to make above sql query output in 3 pages.
order_number item_id quantity item_desc
1001 1 10 apple
1001 2 20 banana
when i click next_page it output below:
order_number item_id quantity item_desc
1002 2 50 banana
1002 1 30 apple
and when i click next_page again it will output below:
order_number item_id quantity item_desc
1003 3 60 orange
1004 3 50 orange
using url:http://www.oracle.com/technology/pub/articles/oracle_php_cookbook/fuecks_paged.html
please look at three php code below:
php code:
<?php
$con = oci_connect('apps','apps','prod');
$sql = "select distinct h.order_number,h.order_type_id,h.price_list_id
from oe_order_headers_all h
where to_char(h.ordered_date,'YYYYMMDD') = '20060627'
and h.org_id = 82
order by order_number ASC";
$result = oci_parse($con,$sql);
oci_execute($result);
echo "<table border = 1>";
echo "<tr><td>order_number</td>";
echo "<td>order_type</td>";
echo "<td>price_id</td></tr>";
while ($rows = oci_fetch_array($result,BOTH_NUM)) {
echo "<tr><td>". $rows[0]."</td>";
echo "<td>".$rows[1]."</td>";
echo "<td>".$rows[2]."</td></tr>";
?>
pager_functions.php
<?php
function total_pages($total_rows, $rows_per_page) {
if ( $total_rows < 1 ) $total_rows = 1;
return ceil($total_rows/$rows_per_page);
function page_to_row($current_page, $rows_per_page) {
$start_row = ($current_page-1) * $rows_per_page + 1;
return $start_row;
function count_rows(& $conn, $select) {
$sql = "SELECT COUNT(*) AS num_rows FROM($select)";
$stmt = oci_parse($conn,$sql);
oci_define_by_name($stmt,"NUM_ROWS",$num_rows);
oci_execute($stmt);
oci_fetch($stmt);
return $num_rows;
function & paged_result(& $conn, $select, $start_row, $rows_per_page) {
$sql = "SELECT
FROM
SELECT
r.*, ROWNUM as row_number
FROM
( $select ) r
WHERE
ROWNUM <= :end_row
WHERE :start_row <= row_number";
$stmt = oci_parse($conn,$sql);
oci_bind_by_name($stmt, ':start_row', $start_row);
// Calculate the number of the last row in the page
$end_row = $start_row + $rows_per_page - 1;
oci_bind_by_name($stmt, ':end_row', $end_row);
oci_execute($stmt);
// Prefetch the number of rows per page
oci_set_prefetch($stmt, $rows_per_page);
return $stmt;
?>
outpages.php:
<?php
$conn = OCILogon('scott', 'tiger') or die ("Unable to connect to db");
require_once 'pager_functions.php';
$rows_per_page = 3;
$url = 'results.php'; // URL to this script
$sql = 'SELECT * FROM testtable ORDER BY rank ASC'; // The unfiltered
// Get the total page count from the number of rows
$total_rows = count_rows($conn,$sql);
$total_pages = total_pages($total_rows, $rows_per_page);
// Make sure the page number is a sane value
if ( !isset($_GET['page']) ||
!preg_match('/^[0-9]+$/',$_GET['page']) ||
$_GET['page'] < 1 ) {
$_GET['page'] = 1;
} else if ( $_GET['page'] > $total_pages ) {
$_GET['page'] = $total_pages;
// Translate the page number into a starting row number
$start_row = page_to_row($_GET['page'], $rows_per_page);
// Filter to a single page of rows
$stmt = & paged_result($conn, $sql, $start_row, $rows_per_page);
?>
<table width="600">
<caption>Feedster Top 500 Blogs [#<?php echo $_GET['page']; ?>]</caption>
<thead>
<tr>
<th>Rank</th>
<th>Blog</th>
<th>Inbound Links</th>
</tr>
</thead>
<tbody>
<?php while (OCIFetchinto($stmt,$row,OCI_ASSOC)) { ?>
<tr valign="top">

Hi,
Your table testtable is defined as follows:
create table testtable (
order_number number(4),
item_id number(4),
quantity number(8),
item_desc varchar2(16)
In your script, you are refering to the columns 'RANK', 'NAME', 'URL' and 'LINKS'!!!
They simly doesn't exist.
You simply copied and pasted a snippet from the oracle-php-cookbook without adapting it to your needs. (And I assume without understanding, what that code will do.)
