données de comptage et le regroupement par semaine dans mysql

Question

c'est ma table DB:

CREATE TABLE IF NOT EXISTS `inspection_report` (
    `Inspection_datetime` datetime NOT NULL, 
    `Line` char(5) NOT NULL, 
    `S` int(11) NOT NULL, 
    `A` int(11) NOT NULL, 
    `B` int(11) NOT NULL, 
    `C` int(11) NOT NULL, 
INSERT INTO `inspection_report` (`Inspection_datetime`,`Line`,`S`, `A`, `B`, `C`) VALUES 
('2010-09-01 09:08:01','FA 05',0, 0, 0, 0),('2010-09-02 14:24:35','FA 07',0, 0, 1, 0),('2010-09-01 09:08:01','fa 05',0, 1, 1, 0),('2010-09-01 16:24:04','FA 03', 0, 1, 0, 0); 

J'ai beaucoup de données pour cette table.how dois-je faire si je veux montrer le résultat comme:

Line  1st week  2nd week  3rd week 4th week 5th week total 
    FA 03  20    32   10   12   35  109 
    FA 05  12     5   10   10   25   62 
    FA 07   0     0   1   1   0   2 

Il y a beaucoup de données pour un mois. Je veux les séparer en comptant pour une semaine.Si il y a des données qui ont atteint environ une semaine, alors le script les comptera automatiquement et les partagera dans la 1ère semaine, 2ème semaine, 3ème semaine, et ainsi de suite. comment je fais ça? ou avez-vous une idée? Pourquoi ne pas utiliser la commande YEARweek()?

Answer 1

SELECT 
    A.Line, 
    week1.1stweek, 
    week2.2ndweek, 
    ... 
    IFNULL(week1.1stweek,0) + IFNULL(week2.2ndweek,0) + .... AS total 
FROM 
    inspection_report AS A 
LEFT JOIN (
    SELECT Line, (SUM(S) + SUM(A) + SUM(B)*0.4 + SUM(C)*0.1)/COUNT(Serial_number) AS 1stweek FROM inspection_report WHERE DAY(Inspection_datetime) BETWEEN 1 AND 7 GROUP BY Line, WEEK, YEAR) AS week1 USING (Line) 
LEFT JOIN (
    SELECT Line, (SUM(S) + SUM(A) + SUM(B)*0.4 + SUM(C)*0.1)/COUNT(Serial_number) AS 2ndweek FROM inspection_report WHERE DAY(Inspection_datetime) BETWEEN 8 AND 14 GROUP BY Line, WEEK, YEAR) AS week2 USING (Line) 
... 
GROUP BY Line 

Answer 2

Vous pouvez utiliser la fonctionnalité de tableau croisé dynamique de SQL Server. Voir l'exemple suivant.

CREATE TABLE MyData 
(
    ItemDate DATETIME, 
    ItemName VARCHAR(200), 
    ItemQty INT 
) 
GO 

DECLARE @I INT 
SET @i = 1 
WHILE @i < 1000 
BEGIN 
    INSERT INTO MyData VALUES(GETDATE()-@I, 'NAME ' + CONVERT(VARCHAR(5),@I % 5), RAND()*100) 
    SET @I = @I + 1 
END 
GO 

SELECT ItemName, [1] AS 'WEEK-1', [2] AS 'WEEK-2', [3] AS 'WEEK-3', [4] AS 'WEEK-4' 
FROM (SELECT ItemName, DATEPART(wk, ItemDate) WeekNum, ItemQty 
     FROM MyData) AS SourceTable 
PIVOT 
(
    SUM(ItemQty) 
    FOR WeekNum IN ([1], [2], [3], [4]) 
) AS PivotTable; 

Answer 3

Vous devez faire quelque chose comme ça

SELECT 
    n.name, 
    w1.amount, 
    w2.amount, 
    ... 
    IFNULL(w1.amount,0) + IFNULL(w2.amount,0) + .... AS total 
FROM 
    yourTable AS n 
LEFT JOIN (
    SELECT name, SUM(qty) AS amount FROM yourTable WHERE DAY(date) BETWEEN 1 AND 7 GROUP BY name 
) AS w1 USING (name) 
LEFT JOIN (
    SELECT name, SUM(qty) AS amount FROM yourTable WHERE DAY(date) BETWEEN 8 AND 14 GROUP BY name 
) AS w2 USING (name) 
...

exemple requête de pivot:

SELECT 
    IFNULL(empId,'Totals') AS EmpId, 
    sums.2005, sums.2006, sums.2007, 
    sums.2005 + sums.2006 + sums.2007 AS Sums 
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; 
+--------+----------+----------+----------+-----------+ 
| EmpId | 2005  | 2006  | 2007  | Sums  | 
+--------+----------+----------+----------+-----------+ 
| 1  | 12000.00 | 18000.00 | 25000.00 | 55000.00 | 
| 2  | 15000.00 | 6000.00 |  0.00 | 21000.00 | 
| 3  |  0.00 | 20000.00 | 24000.00 | 44000.00 | 
| Totals | 27000.00 | 44000.00 | 49000.00 | 120000.00 |
