php - SELECT SUM 数据等级和资源 ID #9 错误 PHP

Question

我有一个网站，其中登录的成员存储在名为“用户”的表下

‘用户’表

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

用户在名为“sales_list”的单独表中的“sales_points”字段中有销售数据。

'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

基本上我想做的是一个查询:

一个。计算“sales_list”中每个用户的“sales_points”总数

B.列出 100 个用户，得分最高的用户排在最前面，然后在下面排名次高，依此类推...

C.我不是在排名数字，而是订单本身。

使用下面的代码，我让 100 个用户打印正常，但是当它打印时，我在“总点数”列中收到“资源 ID #9”消息。谁能帮忙？

我要打印的内容

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

您不会获取第一个结果。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);
