[英]Mysql count with descending with join and where clause ,two tables, limit?
在這里,我實現了兩個表(頁面,頁面統計)。我需要使用這些表中的連接獲取最后五個記錄的結果,並且我需要第二個表中的cID字段的計數(頁面統計),我需要將計數結果顯示在下降。
注意:主要ID為cID。
![pagestatistics] [1]![pages] [2]
<?php
$recentpageviews =mysql_query("SELECT Distinct(cID) FROM `pagestatistics` order by `pstID` desc limit 0,5");
$downloads=mysql_num_rows($recentpageviews);
$k=1;
$cid="";
while($views_values=mysql_fetch_array($recentpageviews))
{
$cid.=",".$views_values['cID'];
$k++;}
}
$explode =explode(",",$cid);
for($i=1;$i<count($explode);$i++)
{
$sql=mysql_query("select Distinct(a.cID),count(a.cID) as clicks,b.cFilename,a.date from pagestatistics as a left join pages as b on a.cID=b.cID where a.cID='".$explode[$i]."' order by a.cID desc");
$res=mysql_fetch_array($sql);
?>
<tr>
<td class='ccm-site-statistics-downloads-title'><?php echo $res['cFilename'];?></td>
<td class='ccm-site-statistics-downloads-title'><?php echo $res['clicks'];?></td>
<td class='ccm-site-statistics-downloads-title'><?php echo $res['date'];?></td>
</tr>
<?php }?>
如何以降序顯示所有記錄。 預先感謝。
您可以通過這種方式來執行此操作,只需在ORDER BY
子句中用,
分隔count
$sql=mysql_query("select Distinct(a.cID),count(a.cID) as clicks,b.cFilename,a.date
from pagestatistics as a left join pages as b on a.cID=b.cID
where a.cID='".$explode[$i]."' order by a.cID,clicks desc");
