| //資料庫連接就不寫在這裡面了 $s = isset( $_GET['s'] )?$_GET['s']:0; $e = isset( $_GET['e'])?$_GET['e']:50; $count =85000; if( $s < $count ) { $sql = "select * from 表首碼_info where isget =0 order by id desc limit $s,$e "; $query = mysql_query( $sql ); while( $rs = mysql_fetch_array( $query ) ) { $id = $rs['id']; $sss = $rs['sss']; $typeid = $rs['typeid']; $isget = $rs['isget']; $sql = "insert into 表首碼_info_bak (id,表首碼,typeid,isget) values('$id','$sss','$typeid','$isget')"; mysql_query( $sql ) ; echo $sql; //exit; $sqlu = "update 表首碼_info set isget=1 where id =".$rs['id']; mysql_query( $sqlu ); } echo '正在處理資料,當前為'.$s.'條......'; } else { echo '完成所有資料處理 再隨機排序一次'; } ?> |
