我正在寻找通过查询我们数据库中的表来创建图表。

我无法理解如何从数据库中水平获取数据，以便很好地插入图表。

人们通常如何为除了要水平输入的数据之外的图表准备数据？

我正在使用 PHP 和 mysql。

My->Mysql 查询 =:

SELECT SUM( production_net ) AS prodnet, production_shift, CONCAT( WEEK( production_date ) , '-', YEAR( production_date )) AS weekno
    FROM production
    WHERE production_shift IN('1','2','3')
    AND product_id = '1319'
    AND production_date
    BETWEEN '2013-01-01'
    AND '2013-06-30'
    GROUP BY production_shift, weekno
    ORDER BY production_shift, CASE weekno
    WHEN '0-2013' THEN 1
    WHEN '1-2013' THEN 2
    WHEN '2-2013' THEN 3
    WHEN '3-2013' THEN 4
    WHEN '4-2013' THEN 5
    WHEN '5-2013' THEN 6
    WHEN '6-2013' THEN 7
    WHEN '7-2013' THEN 8
    WHEN '8-2013' THEN 9
    WHEN '9-2013' THEN 10
    WHEN '10-2013' THEN 11
    WHEN '11-2013' THEN 12
    WHEN '12-2013' THEN 13
    WHEN '13-2013' THEN 14
    WHEN '14-2013' THEN 15
    WHEN '15-2013' THEN 16
    WHEN '16-2013' THEN 17
    WHEN '17-2013' THEN 18
    WHEN '18-2013' THEN 19
    WHEN '19-2013' THEN 20
    WHEN '20-2013' THEN 21
    WHEN '21-2013' THEN 22
    WHEN '22-2013' THEN 23
    WHEN '23-2013' THEN 24
    WHEN '24-2013' THEN 25
    WHEN '25-2013' THEN 26
    WHEN '26-2013' THEN 27
    WHEN '27-2013' THEN 28
    WHEN '28-2013' THEN 29
    WHEN '29-2013' THEN 30
    WHEN '30-2013' THEN 31
    WHEN '31-2013' THEN 32
    WHEN '32-2013' THEN 33
    WHEN '33-2013' THEN 34
    WHEN '34-2013' THEN 35
    WHEN '35-2013' THEN 36
    WHEN '36-2013' THEN 37
    WHEN '37-2013' THEN 38
    WHEN '38-2013' THEN 39
    WHEN '39-2013' THEN 40
    WHEN '40-2013' THEN 41
    WHEN '41-2013' THEN 42
    WHEN '42-2013' THEN 43
    WHEN '43-2013' THEN 44
    WHEN '44-2013' THEN 45

我认为这应该是您正在寻找的：

SELECT
    CONCAT(WEEK(production_date), '-', YEAR(production_date)) weekno,
    SUM(CASE WHEN production_shift = 1 THEN production_net ELSE 0 END) shift_1_net,
    SUM(CASE WHEN production_shift = 2 THEN production_net ELSE 0 END) shift_2_net,
    SUM(CASE WHEN production_shift = 3 THEN production_net ELSE 0 END) shift_3_net,
WHERE production_shift IN(1, 2, 3) AND product_id = 1319 AND
    production_date BETWEEN '2013-01-01' AND '2013-06-30'
GROUP BY weekno
ORDER BY YEAR(production_date), WEEK(production_date)

顺便说一句，我认为ORDER BY返回行的顺序与你的相同，而且更简单:)

Mostacho 几乎完美，我必须删除一个逗号，添加我从中提取的表，并且最后仍然使用巨大的 case 语句。所有功劳归功于他，但这是我的工作查询。希望它可以帮助别人

SELECT
    CONCAT(WEEK(production_date), '-', YEAR(production_date)) weekno,
    SUM(CASE WHEN production_shift = '1' THEN production_net ELSE 0 END) shift_1_net,

    SUM(CASE WHEN production_shift = '3' THEN production_net ELSE 0 END) shift_3_net
    FROM production
WHERE production_shift IN('1', '2', '3') AND product_id = '1319' AND
    production_date BETWEEN '2013-01-01' AND '2013-06-30'
