SUM兩個表

Question

的UNION SQL選擇的一些列

我有這個疑問

SELECT Month(date) AS Monthly, Year(date) AS Annual, COUNT(idcad) AS NumCad, SUM(CONVERT(FLOAT, valorpag)) AS Valor FROM PI_AS 
WHERE (status = 'Paid' OR status = 'Available') AND platform = 'Sales' 
GROUP BY Year(date), Month(date) 
ORDER BY Year(date), Month(date) 

樣品結果：

Monthly | Annual | NumCad | Valor 
     3 | 2014 |  62 | 72534 
     4 | 2014 |  7 | 8253.6 
     5 | 2014 |  42 | 45356.39 
     6 | 2014 |  36 | 33343.19 
     7 | 2014 |  5 | 4414.6 

與此查詢

SELECT Month(date) AS Monthly, Year(date) AS Annual, COUNT(idcad) AS NumCad, SUM(CONVERT(FLOAT, valorpag)) AS Valor FROM PI_PP 
WHERE (status = 'Completed') AND platform = 'Sales' 
GROUP BY Year(date), Month(date) 
ORDER BY Year(date), Month(date) 

樣品結果：

Monthly | Annual | NumCad | Valor 
     4 | 2014 |  6 | 2572.80 
     5 | 2014 |  8 | 7828 
     6 | 2014 |  3 | 3891.60 
     7 | 2014 |  2 | 278.3 

我試圖UNION查詢：

SELECT Month(date) AS Monthly, Year(date) AS Annual, COUNT(idcad) AS NumCad, SUM(CONVERT(FLOAT, valorpag)) AS Valor FROM PI_AS 
WHERE (status = 'Paid' OR status = 'Available') AND platform = 'Sales' 
GROUP BY Year(date), Month(date) 
UNION 
SELECT Month(date) AS Monthly, Year(date) AS Annual, COUNT(idcad) AS NumCad, SUM(CONVERT(FLOAT, valorpag)) AS Valor FROM PI_PP 
WHERE (status = 'Completed') AND platform = 'Sales' 
GROUP BY Year(date), Month(date) 
ORDER BY Year(date), Month(date) 

但是當我這樣做，它與同一個月重複的行...我要的NumCad和Valor同月

的聯盟SUM導致這樣的事情：

Monthly | Annual | NumCad | Valor 
     6 | 2014 |  3 | 3891.60 
     6 | 2014 |  36 | 33343.19 
     7 | 2014 |  5 | 4414.6 
     7 | 2014 |  2 | 278.3 

，但我想這一點：

Monthly | Annual | NumCad | Valor 
     6 | 2014 |  39 | 37234.79 
     7 | 2014 |  7 | 4692.9 

有什麼想法？

Answer 1

首先，你需要在數據上執行工會，然後做了彙總：

SELECT 
    Month(data.date) AS Monthly, 
    Year(data.date) AS Annual, 
    COUNT(data.idcad) AS NumCad, 
    SUM(CONVERT(FLOAT, data.valorpag)) AS Valor 
FROM 
    (SELECT date, idcad, valorpag FROM PI_AS 
    WHERE (status = 'Paid' OR status = 'Available') AND platform = 'Sales' 
    UNION ALL 
    SELECT date, idcad, valorpag FROM PI_PP 
    WHERE (status = 'Completed') AND platform = 'Sales' 
    ) data 
GROUP BY Year(data.date), Month(data.date) 
ORDER BY Year(data.date), Month(data.date) 

Answer 2

把你查詢到一個子查詢aqnd從中選擇：

select monthly, annual, sum(numcad),sum(valor) 
from 
(SELECT Month(date) AS Monthly, Year(date) AS Annual, COUNT(idcad) AS NumCad, SUM(CONVERT(FLOAT, valorpag)) AS Valor FROM PI_AS 
WHERE (status = 'Paid' OR status = 'Available') AND platform = 'Sales' 
GROUP BY Year(date), Month(date) 
UNION 
SELECT Month(date) AS Monthly, Year(date) AS Annual, COUNT(idcad) AS NumCad, SUM(CONVERT(FLOAT, valorpag)) AS Valor FROM PI_PP 
WHERE (status = 'Completed') AND platform = 'Sales' 
GROUP BY Year(date), Month(date) 
)a 
group by monthly, annual 
ORDER BY monthly, annual 

Answer 3

這應該可以解決你想要什麼：

SELECT Monthly, Annual, SUM(NumCad), SUM(Valor) 
FROM 
(
    SELECT Month(date) AS Monthly, Year(date) AS Annual, COUNT(idcad) AS NumCad, SUM(CONVERT(FLOAT, valorpag)) AS Valor FROM PI_AS 
    WHERE (status = 'Paid' OR status = 'Available') AND platform = 'Sales' 
    GROUP BY Year(date), Month(date) 
    UNION 
    SELECT Month(date) AS Monthly, Year(date) AS Annual, COUNT(idcad) AS NumCad, SUM(CONVERT(FLOAT, valorpag)) AS Valor FROM PI_PP 
    WHERE (status = 'Completed') AND platform = 'Sales' 
    GROUP BY Year(date), Month(date) 
) s 
GROUP BY Annual, Monthly
