用ODBC的分页显示

<?php $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; ?> <table> <tr> <td> 共<?php echo $pagecount ?>页;;<?php if($pages != 1)echo "<a href=show.php3?pages=1>";?>首页<?php if($pages != 1)echo "</a>"?>;;<?php if($pages != 1)echo "<a href=show.php3?pages=".$fpages.">"?>前页<?php if($pages != 1)echo "</a>"?>;;<?php if($pages != $pagecount)echo "<a href=show.php3?pages=".$bpages.">"?>后页<?php if($pages != $pagecount)echo "</a>"?> <?php if($pages != $pagecount)echo "<a href=show.php3?pages=".$pagecount.">"?> 尾页<?php if($pages != $pagecount)echo "</a>"?> </td> </tr></table> <?php $firstshow = ($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."'
