如何在此MySQL查询中获得每个结果的计数？

Question

我有一张表，其中每行跟踪有关链接何时被点击的详细信息。该查询显示，前5页，用户是在当他们点击链接：

$pop_pages = ("SELECT url FROM clicks WHERE link = '$link_id' GROUP BY url ORDER BY url ASC LIMIT 5"); 

foreach($pop_pages as $page) { 

$page_string = $page_string."<li>".$page->url."</li>"; 

} 

这将使前5名最频繁点击的URL列表。如何在此查询中添加点击次数的次数？

喜欢的东西：

$page_string = $page_string."<li>".$page->url." (X clicks)</li>"; 

Answer 1

试试这个：

$pop_pages = ("SELECT url, count(url) as c FROM clicks WHERE link = '$link_id' GROUP BY url ORDER BY url ASC LIMIT 5"); 

foreach($pop_pages as $page) { 

$page_string = $page_string."<li>".$page->url." (".$page->c." clicks)</li>"; 

} 

Answer 2

你可以做这样的事情：

$pop_pages = ("SELECT url, COUNT(*) as count FROM clicks WHERE link = '$link_id' GROUP BY url ORDER BY url ASC LIMIT 5"); 

foreach($pop_pages as $page) { 

    $page_string = $page_string."<li>".$page->url." (".$page->count." clicks)</li>"; 

}
