PHPで2つの類似したフィールドをグループ化する方法は?
GROUP BY DATE(bill.date)、bill.agent_idで試しましたが、機能しません
テーブル構造1: http: //i.stack.imgur.com/yvBF0.jpg(テーブル名はbill_agents)
テーブル構造2: http: //i.stack.imgur.com/38tKh.jpg(テーブル名はbill)
現在の結果
+---------+----+----+----+-----+----+
| | 1 | 2 | 3 | 4 | 5 |
+---------+----+----+----+-----+----+
| Agent 1 | 35 | 0 | 0 | 0 | 0 |
| Agent 2 | 0 | 10 | 0 | 0 | 0 |
| Agent 1 | 0 | 0 | 12 | 0 | 0 |
| Agent 3 | 0 | 0 | 0 | 100 | 0 |
| Agent 6 | 0 | 0 | 0 | 9 | 0 |
| Agent 2 | 0 | 0 | 0 | 9 | 14 |
+---------+----+----+----+-----+----+
1,2,3,4,5....は日付からの日数です
でも次のようになりたい
+---------+----+----+----+-----+----+----+
| | 1 | 2 | 3 | 4 | 5 |total
+---------+----+----+----+-----+----+----+
| Agent 1 | 35 | 0 | 12 | 0 | 0 |47 |
| Agent 2 | 0 | 10 | 0 | 0 | 14 |28 |
| Agent 3 | 0 | 0 | 0 | 100 | 0 |100 |
| Agent 6 | 0 | 0 | 0 | 9 | 0 | 9 |

私が現在使用している以下に貼り付けられたPHPコード。
<table width="100%" border="1" cellspacing="4" cellpadding="1">
