PHP和MySQL：查詢到 「和」 2個從PHP

Question

行

我有如下表：

+------------+-------+------------+-----------+ 
| date  | time | custom_id | Number | 
+------------+-------+------------+-----------+ 
| 01/17/2014 | 00:00 | ABC123  | 15  | 
| 01/17/2014 | 00:00 | HEY567  | 25  | 
| 01/17/2014 | 00:30 | ABC123  | 17  | 
| 01/17/2014 | 00:30 | HEY567  | 28  | 
| 01/17/2014 | 01:00 | ABC123  | 17  | 
| 01/17/2014 | 01:00 | HEY567  | 28  | 
| 01/17/2014 | 01:30 | ABC123  | 17  | 
| 01/17/2014 | 01:30 | HEY567  | 28  | 
+------------+-------+------------+-----------+ 

我怎樣才能和2行（總數）具有相同CUSTOM_ID & DATE當給定的時間只是：30分鐘的差異將它舍入到：00並刪除：30？它應該看起來像這樣到底：

+------------+-------+------------+-----------+ 
| date  | time | custom_id | Number | 
+------------+-------+------------+-----------+ 
| 01/17/2014 | 00:00 | ABC123  | 32  | 
| 01/17/2014 | 00:00 | HEY567  | 53  | 
| 01/17/2014 | 01:00 | ABC123  | 34  | 
| 01/17/2014 | 01:00 | HEY567  | 56  | 
+------------+-------+------------+-----------+ 

我該如何使用PHP或可能的MySQL查詢來完成此操作？

在此先感謝

Answer 1

這應該工作

SELECT date, MIN(time) as time, custom_id, SUM(Number) as Number 
FROM table 
GROUP BY date, custom_id, HOUR(time)
