Question

说，我有两张桌子......

Table 1 : Hotels
   hotel_id   hotel_name
       1          abc
       2          xyz
       3          efg

Table 2 : Payments
    payment_id     payment_date     hotel_id     total_amt    comission
       p1           23-03-2010          1          100           10
       p2           23-03-2010          2          50            5
       p3           23-03-2010          2          200           25
       p4           23-03-2010          1          40            2

现在，我需要从两个表中获取以下详细信息

鉴于特定日期（例如，23-03-2010），在该特定日期已支付的每家酒店的total_amt总和。
根据酒店名称

示例输出如下......

+------------+------------+------------+---------------+
| hotel_name |   date     |  total_amt |   commission  |
+------------+------------+------------+---------------+
| * abc      | 23-03-2010 |     140    |      12       |
+------------+------------+------------+---------------+
|+-----------+------------+------------+--------------+|
|| paymt_id  |   date     |  total_amt |   commission ||
|+-----------+------------+------------+--------------+|
||   p1      | 23-03-2010 |     100    |     10       ||
|+-----------+------------+------------+--------------+|
||   p4      | 23-03-2010 |     40     |     2        ||
|+-----------+------------+------------+--------------+|
+------------+------------+------------+---------------+
| * xyz      | 23-03-2010 |     250    |      30       |
+------------+------------+------------+---------------+
|+-----------+------------+------------+--------------+|
|| paymt_id  |   date     |  total_amt |   commission ||
|+-----------+------------+------------+--------------+|
||   p2      | 23-03-2010 |     50     |      5       ||
|+-----------+------------+------------+--------------+|
||   p3      | 23-03-2010 |     200    |      25      ||
|+-----------+------------+------------+--------------+|
+------------------------------------------------------+

在必须打印的表格样本上方......

这个想法首先要显示每家酒店的统一细节，当点击酒店名称旁边的“*”时，付款细节的细分将变得可见......但这可以通过一些jquery来完成。。！表本身可以用php ...

现在我正在使用两个单独的查询：一个用于获取按酒店名称分组的金额和佣金的总和。接下来是获取表中具有该日期的每个条目的单独行。当然，这是因为对计算sum（）的记录进行分组只会为每个酒店返回一行，并且金额总和...

有没有办法将这两个查询合并为一个，并以更优化的方式进行操作...... ??

希望我很清楚..感谢您的时间和回复...

编辑：添加查询

查询得到总和（）

 
SELECT DATE_FORMAT($payments.payment_date, '%d-%m-%Y %T') as payment_date,
        $payments.payment_id AS payment_id,
        $payments.payment_amount AS payment_amount,
        $payments.agent_commision AS commision,
        $payments.comm_percentage AS percentage,
        $hotels.hotel_name AS hotel
        SUM($payments.payment_amount)  AS tot_amt
        SUM($payments.agent_commision) AS tot_ag_comsn
FROM $payments
JOIN $hotels
ON   $payments.hotel_id = $hotels.hotel_id
WHERE DATE_FORMAT(payment_date,'%d-%m-%Y') = '$date_report'
GROUP BY $payments.hotel_id
ORDER BY $payments.payment_date ASC

查询以获取各行

   
SELECT DATE_FORMAT($payments.payment_date, '%d-%m-%Y %T') as payment_date,
            $payments.payment_id AS payment_id,
            $payments.payment_amount AS payment_amount,
            $payments.agent_commision AS commision,
            $payments.comm_percentage AS percentage,
            $hotels.hotel_name AS hotel
FROM $payments
JOIN $hotels
ON   $payments.hotel_id = $hotels.hotel_id
WHERE DATE_FORMAT(payment_date,'%d-%m-%Y') = '$date_report'
GROUP BY $payments.payment_date
ORDER BY $payments.payment_date ASC

我将两个查询返回的行添加到两个单独的临时表中，然后使用php打印如上所示的表...

Answer 1

这是报告编写者的领域，或编程语言中的等效逻辑。

有没有办法优化这个mysql查询...？
