Question

的總和

可能重複：
MySQL Count data for last 7 days

我有，我需要展示場之和的問題。可以說我有一個記錄如下，

detectDate  |isp |infection | count 
-------------------------------------- 
2012-10-02 01:00|aaaa |malware |3 
2012-10-02 01:30|bbbb |malware |2 
2012-10-02 01:33|bbbb |spy-eye |2 
2012-10-02 01:45|aaaa |DDos  |1 
2012-10-03 01:50|cccc |malware |2 
2012-10-03 02:00|dddd |TDSS  |2 
2012-10-03 04:50|dddd |TDSS  |3 

，我想顯示的輸出，它會顯示每一天所有感染的總和如下，

detectDate |infection | count 
------------------------------- 
2012-10-02 |DDos  |1 
2012-10-02 |malware |5 
2012-10-02 |spy-eye |2 
2012-10-02 |TDSS  |0 
2012-10-03 |DDos  |0 
2012-10-03 |malware |2 
2012-10-03 |spy-eye |0 
2012-10-03 |TDSS  |5 

我用這個查詢，

SELECT DATE_FORMAT(detectDate, '%Y-%m-%d') AS detectDate, infection, SUM(count) 
FROM `tbl_correlateddata` 
GROUP BY DATE_FORMAT(detectDate, '%Y-%m-%d') , infection 

但它只如下是不我的要求給出了把..

detectDate |infection | count 
------------------------------- 
2012-10-02 |DDos  |1 
2012-10-02 |malware |5 
2012-10-02 |spy-eye |2 
2012-10-03 |malware |2 
2012-10-03 |TDSS  |5 

任何幫助將非常有幫助:) 非常感謝你:)感激:)

但不相似

Answer 1

SELECT e.*, COALESCE(SUM(d.`count`),0) `SUM of count` 
FROM 
(
    SELECT c.detectDate, a.infection 
    FROM 
    (
     SELECT DISTINCT infection 
     FROM tbl_correlateddata 
    ) a CROSS JOIN 
    (
     SELECT DISTINCT DATE(detectDate) detectDate 
     FROM tbl_correlateddata 
    ) c 
) e LEFT JOIN tbl_correlateddata d 
    ON DATE(d.detectDate) = e.detectDate AND 
     d.infection = e.infection 
GROUP BY detectDate, infection 
ORDER BY e.detectDate, e.infection

或

SELECT DATE_FORMAT(e.detectDate, '%Y-%m-%d'), 
     e.infection, 
     COALESCE(SUM(d.`count`),0) `SUM of count` 
FROM 
(
    SELECT c.detectDate, a.infection 
    FROM 
    (
     SELECT DISTINCT infection 
     FROM tbl_correlateddata 
    ) a CROSS JOIN 
    (
     SELECT DISTINCT DATE(detectDate) detectDate 
     FROM tbl_correlateddata 
    ) c 
) e LEFT JOIN tbl_correlateddata d 
    ON DATE(d.detectDate) = e.detectDate AND 
     d.infection = e.infection 
GROUP BY e.detectDate, e.infection 
ORDER BY e.detectDate, e.infection
