Question

我有一些链接，可以借助数据库中的临时数据显示iframe上的数据我在查询字符串

的帮助下获取此数据

包含链接的页面是

<style type="text/css">
a
{
    text-decoration:none;
}
.Menu
{
    width:150px;
    float:left;
}
.fr
{
    width:800px;
    height:800px;
    float:right
}

</style>
<div class="Menu">
<?php
mysql_connect("localhost","dbname","password");
mysql_select_db("dbname");
$sql="select * from NSEIndices_latest";
$result=mysql_query($sql);
while($row=mysql_fetch_array($result))
{
$tpnt=$row['TickerPlantCode'];  //nse indice code
$indexname=$row['IndexName']; //nse indice index name
?>
  <tr>
    <td><a href="http://mastertrade.in/master/wpfiles/gtnsegainers.php?tpnt=<?php echo $tpnt;?>&indexname=<?php echo $indexname;?>" target="fr"><?php echo $indexname;?></a><br></td>
  </tr>
    <?php }?>
    </div>
    <div class="fr">
    <iframe height="780" width="780" scrolling="no" name="fr"></iframe>
    </div>

现在来自上一页的链接在此页面的查询字符串的帮助下获取数据，临时表由各种表中的collectiong数据创建但是从该临时表中检索数据时出现错误

临时表的页面是

<table class="table" cellspacing="0" width="100%">
  <tr>
    <td align="left" valign="middle" style="border:#e7e7e7 1px solid; background-color:#f9f9f9;">Company Name

  </tr>
  <?php } ?>
</table>

我得到的错误是

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/mastertr/public_html/master/wpfiles/gtnsegainers.php on line 58

Answer 1

TEMPORARY表具有一个连接的生命周期，因此如果您在浏览器的一个请求期间创建表，然后想要在另一个请求中从中获取数据....它就不再存在了。该表不存在，您的查询因no such table in database错误而失败。

在MySQL中使用临时表
