Erste Reihe von SubQuery Graf, die Gruppe durch - MySQL

Question

ich zur Zeit eine Tabelle mit folgendem Schema hat:

CREATE TABLE `order_handling` (
    `id` int(11) NOT NULL AUTO_INCREMENT, 
    `oh_no` varchar(24) COLLATE utf8_unicode_ci DEFAULT NULL, 
    `date_request` datetime DEFAULT NULL, 
    `status` smallint(4) DEFAULT NULL, 
    PRIMARY KEY (`id`) 
) ENGINE=InnoDB AUTO_INCREMENT=14 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci; 

Ich mag ausführen Abfrage, die wie folgt führen:

+-------------------------------------------------------------+ 
| MonthDone | OhProgress | OhHold | OhCancel | OhDone | Total | 
+-------------------------------------------------------------+ 
| June 2016 |   2 |  1 |  1 |  3 |  7 | 
| July 2016 |   6 |  1 |  null | null |  7 | 
+-------------------------------------------------------------+ 

Meine Suche ist,

SELECT 
    DATE_FORMAT(`oh`.`date_request`, '%m-%Y') AS `IdMonth`, 
    (SELECT COUNT(*) FROM order_handling as oh1 WHERE `oh1`.`status` IN (1,2) GROUP BY IdMonth) As OhProgress, 
    (SELECT COUNT(*) FROM order_handling as oh2 WHERE `oh2`.`status` IN (3) GROUP BY IdMonth) As OhHold, 
    (SELECT COUNT(*) FROM order_handling as oh3 WHERE `oh3`.`status` IN (4) GROUP BY IdMonth) As OhCancel, 
    (SELECT COUNT(*) FROM order_handling as oh3 WHERE `oh3`.`status` IN (5) GROUP BY IdMonth) As OhDone, 
    (SELECT COUNT(*) FROM order_handling as oh5 WHERE `oh5`.`status` IN (1,2,3,4,5) GROUP BY IdMonth) As SumTotal 
FROM `order_handling` `oh` 
GROUP BY DATE_FORMAT(`oh`.`date_request`, '%M %Y') 
ORDER BY `oh`.`date_request` ASC 

Die Ausgabe wurde nicht erwartet. Wenn ich SubQuery GROUP BY ändern mit DATE_FORMAT(date_request, '%m-%Y') wie folgt:

SELECT 
    DATE_FORMAT(`oh`.`date_request`, '%m-%Y') AS `IdMonth`, 
    (SELECT COUNT(*) FROM order_handling as oh1 WHERE `oh1`.`status` IN (1,2) GROUP BY DATE_FORMAT(`oh1`.`date_request`, '%m-%Y')) As OhProgress, 
    (SELECT COUNT(*) FROM order_handling as oh2 WHERE `oh2`.`status` IN (3) GROUP BY DATE_FORMAT(`oh2`.`date_request`, '%m-%Y')) As OhHold, 
    (SELECT COUNT(*) FROM order_handling as oh3 WHERE `oh3`.`status` IN (4) GROUP BY DATE_FORMAT(`oh3`.`date_request`, '%m-%Y')) As OhCancel, 
    (SELECT COUNT(*) FROM order_handling as oh4 WHERE `oh4`.`status` IN (5) GROUP BY DATE_FORMAT(`oh4`.`date_request`, '%m-%Y')) As OhDone, 
    (SELECT COUNT(*) FROM order_handling as oh5 WHERE `oh5`.`status` IN (1,2,3,4,5) GROUP BY DATE_FORMAT(`oh5`.`date_request`, '%m-%Y')) As SumTotal 
FROM `order_handling` `oh` 
GROUP BY DATE_FORMAT(`oh`.`date_request`, '%M %Y') 
ORDER BY `oh`.`date_request` ASC 

Es gibt mir Fehler: Subquery Rückkehr mehr als 1 Zeile Hier ist meine SQLFiddle

Bitte helfen, danke

Answer 1

Try this:

SELECT 
    DATE_FORMAT(oh.`date_request`, '%m-%Y') AS `IdMonth`, 
    (SELECT COUNT(*) 
    FROM order_handling as oh1 
    WHERE oh1.`status` IN (1,2) AND 
      `IdMonth` = DATE_FORMAT(oh1.`date_request`, '%m-%Y')) As OhProgress, 
    (SELECT COUNT(*) 
    FROM order_handling as oh2 
    WHERE oh2.`status` IN (3) AND 
      `IdMonth` = DATE_FORMAT(oh2.`date_request`, '%m-%Y')) As OhHold, 
    (SELECT COUNT(*) 
    FROM order_handling as oh3 
    WHERE oh3.`status` IN (4) AND 
      `IdMonth` = DATE_FORMAT(oh3.`date_request`, '%m-%Y')) As OhCancel, 
    (SELECT COUNT(*) 
    FROM order_handling as oh4 
    WHERE oh4.`status` IN (5) AND 
      `IdMonth` = DATE_FORMAT(oh4.`date_request`, '%m-%Y')) As OhDone, 
    (SELECT COUNT(*) 
    FROM order_handling as oh5 
    WHERE oh5.`status` IN (1,2,3,4,5) AND 
      `IdMonth` = DATE_FORMAT(oh5.`date_request`, '%m-%Y')) As SumTotal 
FROM `order_handling` oh 
GROUP BY DATE_FORMAT(oh.`date_request`, '%M %Y') 
ORDER BY oh.`date_request` ASC

Answer 2

Keine Notwendigkeit für Unterabfragen

SELECT 
    DATE_FORMAT(`date_request`, '%m-%Y') AS `IdMonth`, 
    SUM(status IN (1,2)) As OhProgress, 
    SUM(status IN (3)) As OhHold, 
    SUM(status IN (4)) As OhCancel, 
    SUM(status IN (5)) As OhDone, 
    SUM(status IN (1,2,3,4,5)) As SumTotal 
FROM `order_handling` 
GROUP BY DATE_FORMAT(`date_request`, '%M %Y') 
ORDER BY `date_request` ASC
