Træk poster fra ordretabellen for den aktuelle uge

Lad os gøre præcis, hvad du vil:

SELECT
    WEEKDAY(`datetime_field`) AS `week_day`,
    COUNT(*) AS `sale_count`
FROM `orders`
WHERE YEARWEEK(`datetime_field`) = YEARWEEK(NOW())
GROUP BY `week_day`
ORDER BY `week_day` ASC;

Dette returnerer et sæt poster med week_day og sale_count . Få flere oplysninger her . Brug NOW() hvis du bruger lokal datotid eller bruger UTC_TIMESTAMP() hvis du spiller med GMT.

Husk på, at jeg ikke kender dit databasenavn eller felternes navne. Du skal udfylde dem.

ARBEJDSEKSEMPEL:

CREATE TABLE `orders` (
  `OrderID` int(11) NOT NULL AUTO_INCREMENT,
  `OrderDate` datetime NOT NULL,
  `OrderValue` decimal(7,2) unsigned NOT NULL,
  PRIMARY KEY (`OrderID`)
);

INSERT INTO `orders` VALUES ('1', '2012-10-29 14:02:19', '100.00');
INSERT INTO `orders` VALUES ('2', '2012-10-30 14:02:19', '123.00');
INSERT INTO `orders` VALUES ('3', '2012-10-31 14:02:19', '103.00');
INSERT INTO `orders` VALUES ('4', '2012-11-01 14:02:19', '232.00');
INSERT INTO `orders` VALUES ('5', '2012-11-02 14:02:19', '321.00');
INSERT INTO `orders` VALUES ('6', '2012-11-03 14:02:19', '154.00');
INSERT INTO `orders` VALUES ('7', '2012-11-04 14:02:19', '112.00');
INSERT INTO `orders` VALUES ('8', '2012-10-29 14:02:19', '100.00');

SELECT
    WEEKDAY(`OrderDate`) AS `week_day`,
    COUNT(*) AS `sales_count`,
    SUM(`OrderValue`) AS `sales_value`
FROM `orders`
WHERE YEARWEEK(`OrderDate`) = YEARWEEK(NOW())
GROUP BY `week_day`
ORDER BY `week_day` ASC;

Dette er SQL for at oprette en tabel, tilføj 1 ordre pr. dag for denne uge, men 2 om mandagen. Og forespørgslen om at hente rapporten.
