Mysql: How to fetch database data in different variables

Question

<?php
  $sql=mysql_query("SELECT description FROM `tbl_news` where `flag`=1 and `show_at`='notice_board'");
  if(mysql_num_rows($sql)>0)
  {
   $i=1;
   while($row=mysql_fetch_array($sql))
   {
?>
    <br/>
    <img src="images1/left_nav_symbol.png" alt="" /> &nbsp;&nbsp;&nbsp;
    <font color="#000000">
    <?php echo $row['description'];?> <img src="images1/new1.GIF" alt=""/>
    </font>
    <?php
    $i=$i+1;    
   }    
 }
 else
 { 
   echo "No records found.";
 }          

This is my code. I want to fetch values of column description by the latest value, show it by highlighting or set a new button image to it. Is there any solution for it?

Answer 1

要获取最新值，可以使用MAX

MAX(description) in select query

Answer 2

The table should have an auto_increment ID or a datetime field (maybe with the default value NOW() ), indicating when the rows were inserted.

Using this field you can order the results of the query like:

SELECT description FROM `tbl_news` where `flag`=1 and `show_at`='notice_board' ORDER BY `stored_at` DESC
