从数据库中获取您的数据用于制图

Question

我期待通过查询数据库中的表来创建图表。

我无法理解如何从数据库水平获取数据，因此它很好地插入图表。

人们通常如何为图表准备数据，除水平输入数据外？

我使用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

我需要的是这个数据是这样

2013-01-21   67   1503   573 
2013-01-22   85   763   800 

我一直在试图array_merge /推/和大块，但不能得到正确的数据。

Answer 1

我想这应该是你在找什么：

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返回行以相同的顺序为你的，是简单一点:)

Answer 2

Mostacho有它几乎完美，我不得不删除一个逗号，添加我从中拉出来的表格，并在最后仍然使用巨大的病例声明。所有信贷给他，但这里是我的工作查询。希望它可以帮助别人

SELECT 
    CONCAT(WEEK(production_date), '-', YEAR(production_date)) weekno,

    SUM(CASE WHEN production_shift = '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'
