★ 请问怎么使用PHP在Oracle里做分页！？

[phpphp]

要最容易理解 和最容易使的（我是个初学者）
最好不使类：）
谢谢！！

建议你使用adodb.

楼主可以看看吧,这是我写的分页函数.起始最重要的就是那句sql语句!

[erldy]

PHP+ORACLE 分页代码：
//分页程序开始
$display_rows = 10;
$sql = "SELECT COUNT(*) FROM $tbl where msg_sort_id=$sid";
$stmt = Query($c245,$sql);

if (OCIFetch($stmt)) {
$num_rows = OCIResult($stmt,1);
} else {
$num_rows = 0;
}

OCIFreeStatement($stmt);
$page = $_GET['page'];
if (empty($page) || $page == 0) {
$page = 1;
}
$start_range = (($page - 1) * $display_rows) + 1;
$end_range = $page * $display_rows;
$sql = "SELECT msg_id,msg_content,msg_sort_id,msg_sort_name,msg_hide,msg_commend,msg_hits,ROW_NO FROM (SELECT msg_id,";
$sql .= "msg_content,msg_sort_id,msg_sort_name,msg_hide,msg_commend,msg_hits,ROWNUM ROW_NO FROM (SELECT msg_id,msg_content,";
$sql .= "msg_sort_id,msg_sort_name,msg_hide,msg_commend,msg_hits FROM $tbl where msg_sort_id=$sid ORDER BY msg_id desc)) WHERE ROW_NO BETWEEN ";
$sql .= $start_range." AND ".$end_range;

//显示数据

if ($num_rows != 0) {
$stmt = Query($c245,$sql);
while(OCIFetchInto($stmt, &$ary)) {
……
}
}

//显示导航条
if ($num_rows % $display_rows == 0) {
$total_pages = $num_rows / $display_rows;
} else {
$total_pages = ($num_rows / $display_rows) + 1;
settype($total_pages, integer);
}

if ($page != 1) {
echo "<a href='".$PHP_SELF."?page=".($page - 1)."&sid=".$sid."'>上一页</a>";
}

for ($i = 1; $i <= $total_pages; $i++) {
if ($page == $i){
echo " ".$i;
} else {
echo " <a href='".$PHP_SELF."?page=".$i."&sid=".$sid."'>".$i."</a>";
}
}

if ($page < $total_pages) {
echo " <a href='".$PHP_SELF."?page=".($page + 1)."&sid=".$sid."'>下一页</a>";
}
echo "  总页数: <b><font color=red>".$total_pages."</font></b>    总记录数: <b><font color=red>".$num_rows."</font></b>";
//结束分页


用三层子查询来实现，效率很高！

[hahawen]

楼上的写的对,oricle的分页要通过子查询来实现, 所以不建议自己写,建议用adodb来处理数据库问题

[jxyuhua]

<?php
//PEAR中的Pager文件，自己可以下载
include_once('Pager/Pager.php');
$products = getResult($keywords);//将要显示的数据,数组类型
$params = array(
'mode' => 'Jumping',
'perPage' => 5,
'delta' => 5,
'itemData' => $products,
'linkClass' => 'pageResults',
);
$pager = & Pager::factory($params);
$page_data = $pager->getPageData();
$links = $pager->getLinks();
$selectBox = $pager->getPerPageSelectBox();
$pageOffset = $pager->getOffsetByPageId();
for ($i=$pageOffset[0]-1; $i<$pageOffset[1]; $i++) {
//显示
}
echo "Result Pages:  " .$links['all'];
$display = "Displaying %d to %d (of %d products)";
printf($display, $pageOffset[0], $pageOffset[1], $pager->numItems());

[黑夜路人（heiyeluren）]

建议用adodb或者db来做,呵呵

[phpphp]

adodb 是啥？连数据库的？咋使？：P

[-神仙-]

不是和mysql差不多的吗?????
