从这个示例表和数据:
CREATE TABLE sales
(`sales_person_id` int,
`sale_date` datetime,
`sale_amount` int);
INSERT INTO sales
(`sales_person_id`, `sale_date`, `sale_amount`)
VALUES
(1, '2014-01-01 00:00:00', 10),
(1, '2014-01-02 00:00:00', 12),
(2, '2014-01-03 00:00:00', 20),
(1, '2014-01-03 00:00:00', 15),
(1, '2014-01-03 00:00:00', 3),
(3, '2014-01-05 00:00:00', 25)
;
使用@startDate = '2014/01/01'
和@endDate = '2014/01/06'
时,我想以这种格式返回结果:
ID | 20140101 | 20140102 | 20140103 | 20140104 | 20140105 | 20140106 |
----------------------------------------------------------------------
1 | 10 | 12 | 18 | 0 | 0 | 0 |
2 | 0 | 0 | 20 | 0 | 0 | 0 |
3 | 0 | 0 | 0 | 0 | 25 | 0 |
----------------------------------------------------------------------
我确信这可以在一个查询中完成,但我目前还没有任何结果。如果我取得任何进展,我会进行编辑。
