用ODBC的分页显示

$pagesize = 3;//设置每页显示数目

//计算总记录数

$rs_num = "select count(*) as id from table";

$rs_num = odbc_exec($conn_id,$rs_num);

$rs_num = odbc_result($rs_num,"id");

//计算总页数

$pagecount = $rs_num / $pagesize;

$pagecount1 = intval($pagecount);//将总页数取整

$compare = $pagecount - $pagecount1;

switch ($compare){

case "0":

$pagecount = $pagecount1;//总页数

break;

default :

$pagecount1++;

$pagecount = $pagecount1;//总页数

break;

};

if ($pagecount == 0)$pagecount++;

$fpages = $pages-1;

$bpages = $pages+1;

?>

$firstshow = ($pages-1)*$pagesize+1;//确定每页的第一条记录

//找出第一条记录的记录号

$query_string = "SELECT * FROM table Order By id DESC";

$query_string = odbc_exec($conn_id,$query_string);

odbc_fetch_into($query_string,$firstshow,&$idarea);

$idsql = $idarea[0];

//定位查找

if ($pages == $pagecount) {

$rs = "SELECT * FROM table where id <= '".$idsql."' Order By id DESC";

}else{

$rs = "SELECT Top ".$pagesize." * FROM table where id <= '".$idsql."' Order By id DESC";

};

$rs = odbc_exec($conn_id,$rs);

//显示记录

while(odbc_fetch_row($rs)){

};

?>

//关闭连接

odbc_close($conn_id);

?>
