我有这样的来自 mysql 的数据
production_date| production_net| worker_name
------------------------------------------
2013-01-10 | 390 | MMahe
------------------------------------------
2013-01-10 | 400 | RMaloney
------------------------------------------
2013-01-11 | 460 | JBurris
------------------------------------------
2013-01-11 | 210 | MMahe
------------------------------------------
2013-01-14 | 285 | LTaylor
------------------------------------------
我想像这样显示我的结果
operator| 2013-01-10| 2013-01-11| 2013-01-14
--------------------------------------------
MMahe | 390 | 210 |
--------------------------------------------
RMaloney| 400 | |
--------------------------------------------
JBurris | | 460 |
--------------------------------------------
LTaylor | | | 285
--------------------------------------------
我将使用 php。
任何有用的帖子、想法或教程将不胜感激。

您只能通过 MySQL 完成此操作，请查看此链接 http://www.artfulsoftware.com/infotree/qrytip.php?id=78
例如，将该链接中的示例查询修改为如下所示:
SELECT
EmpId,
sums.2005, sums.2006, sums.2007,
FROM (
SELECT
EmpID,
SUM(IF(Yr=2005,sales,0)) As '2005',
SUM(IF(Yr=2006,sales,0)) As '2006',
SUM(IF(Yr=2007,sales,0)) As '2007'
FROM Sales
GROUP BY EmpID WITH ROLLUP
) AS sums;
你将在 MySQL 中得到这样的结果
+--------+----------+----------+----------+
| EmpId | 2005 | 2006 | 2007 |
+--------+----------+----------+----------+
| 1 | 12000.00 | 18000.00 | 25000.00 |
| 2 | 15000.00 | 6000.00 | 0.00 |
| 3 | 0.00 | 20000.00 | 24000.00 |
