Question

我有一个网站，其中登录的成员存储在名为“用户”的表格下

'用户'表

users_sales_guild_id | users_first_name | users_surname
555                  | Jane             | Smith
333                  | John             | Smith
111                  | Mike             | Myers

用户的销售数据包含在＆＃39; sales_points＆＃39;字段位于名为“sales_list”的单独表中。

'sales_list'表

sales_id |  users_sales_guild_id     |  sales_points    |  sales_entry_date
1        |  555                      |  50              |  2013-02-31 00:00:00
2        |  333                      |  30              |  2013-02-31 00:00:00
3        |  111                      |  10              |  2013-02-31 00:00:00
4        |  555                      |  50              |  2013-03-31 00:00:00
5        |  333                      |  30              |  2013-03-31 00:00:00
6        |  111                      |  10              |  2013-03-31 00:00:00

基本上我要做的是查询：

一个。计算＆＃39; sales_points的总金额＆＃39;对于来自＆＃39; sales_list＆＃39;

的每个用户

B中。列出100个用户，其中点数最多的用户位于顶部，然后排名下一个最高点，依此类推......

℃。我不是在排名后，只是订单本身。

使用下面的代码我可以让100位用户打印好，但是在打印时，我在“总点数”列中收到“资源ID＃9”消息。有人可以帮忙吗？

我想要打印什么

Jane Smith   |   100
John Smith   |   60
Mike Myers   |   20

代码：

    <?php 
    require_once ('config.inc.php');

    $page_title = '';
    include ('header.html');

    if (!isset($_SESSION['users_id'])) {

      $url = 'http://' . $_SERVER['HTTP_HOST']
        . dirname($_SERVER['PHP_SELF']);
       // Check for a trailing slash.
       if ((substr($url, -1) == '/') OR (substr($url, -1) == '\\') ) {
            $url = substr ($url, 0, -1); // Chop off the slash.
       }
       // Add the page.
       $url .= 'login.php'; 

    ob_end_clean(); // Delete the buffer.
    header("Location: $url"); 
    exit(); // Quit the script.

Answer 1

你没有取得第一个结果。例如，将其作为数组（mysql_fetch_array()）获取。

// Execute query
$total_query = mysql_query("SELECT SUM(sales_points)
                      FROM sales_list, users
                      WHERE sales_list.users_sales_guild_id = users.users_sales_guild_id
                      AND sales_entry_date
                      BETWEEN '2013-10-01 00:00:00' AND '2013-11-30 23:59:59'");

// Fetch result
$total = mysql_fetch_array($total_query);

Answer 2

你回应这个：

$total = mysql_query("SELECT SUM(sales_points) FROM sales_list,users WHERE sales_list.users_sales_guild_id = users.users_sales_guild_id
    AND sales_entry_date
    BETWEEN '2013-10-01 00:00:00' AND '2013-11-30 23:59:59'
    " );

变量$total包含查询结果，即资源。您应该使用mysql_fetch_assoc或类似函数来提取结果本身。最好给SUM(sales_points)一个别名，即AS total_sales_points，这样您就可以轻松获取。

顺便说一句，mysql _ * - 扩展即将成为deprecated。好的选择包括MySQLi和PDO。

Answer 3

$query = mysql_query("SELECT SUM(sales_points) as points FROM sales_list,users WHERE sales_list.users_sales_guild_id = users.users_sales_guild_id
    AND sales_entry_date
    BETWEEN '2013-10-01 00:00:00' AND '2013-11-30 23:59:59'
    " );
$row = mysql_fetch_object($query);
$total = $row->points;

您正在回显mysql资源，首先需要获取结果，然后您可以回显它们。
