같은 날에 두 개의 특정 값이 발생하는 경우 합계

Question

무기 종류별로 수확 한 날짜가있는 데이터 집합이 있습니다. 데이터는 아래의 예제를 설정 :

입니다 내가 수행하는 것이 무엇

Species Total HarvestMonthDayYear WeaponID WeaponType 
Deer  623 1/14/2017   1   Gun 
Deer  10  1/14/2017   3   Reg Bow 
Deer  15  1/14/2017   4   Crossbow 
Deer  5  9/20/2017   4   Crossbow 
Deer  9  9/21/2017   2   Muzzleloader 
Deer  2  9/21/2017   3   Reg Bow 
Deer  1  9/21/2017   4   Crossbow 
Deer  1  9/21/2017   8   Shotgun 
Deer  10  9/22/2017   1   Gun 
Deer  1  9/22/2017   3   Reg Bow 

"등록 활 '과 같은 날에"석궁 "수확, 나는"양궁 "라는 하나의 행에 결과를 결합하고자하는 때. 일반 활과 석궁이 수확 사슴에 사용되었다 그래서 하나 개의 세트로 사람들을 결합하고 싶습니다 - 2017년 1월 14일 및 2017년 9월 22일에

Species Total HarvestMonthDayYear WeaponID WeaponType 
Deer 623 1/14/2017   1   Gun 
Deer 25  1/14/2017   10  Archery 
Deer 5  9/20/2017   4   Crossbow 
Deer 9  9/21/2017   2   Muzzleloader 
Deer 3  9/21/2017   10  Archery 
Deer 1  9/21/2017   8   Shotgun 
Deer 10  9/22/2017   1   Gun 
Deer 1  9/22/2017   2   Muzzleloader 
Deer 1  9/22/2017   3   Reg Bow 

이 : -처럼 그리고 최종 데이터 세트가 보일 것입니다 그러나 09/20/2017 및 09/22/2017에 - 석궁 또는 일반 활 만 사용되었으므로이 결과는 그대로 남겨 두어야합니다.

이것이 가능합니까? 나는 이것을 코드화하기 시작하는 방법을 생각할 수 없다.

당신 수 구절이 노동 조합과 같은 :

WITH cte AS (
    SELECT Species, HarvestMonthDayYear, SUM(Total) AS Total 
    FROM yourTable 
    WHERE 
     WeaponType IN ('Reg Bow', 'Crossbow') 
    GROUP BY 
     Species, HarvestMonthDayYear 
    HAVING COUNT(DISTINCT WeaponType) = 2 
) 
SELECT 
    t1.Species, t1.Total, t1.HarvestMonthDayYear, t1.WeaponID, t1.WeaponType 
FROM yourTable t1 
LEFT JOIN cte t2 
    ON t1.Species = t2.Species AND 
     t1.HarvestMonthDayYear = t2.HarvestMonthDayYear 
WHERE 
    t2.Species IS NULL OR 
    (t2.Species IS NOT NULL AND WeaponType NOT IN ('Reg Bow', 'Crossbow')) 
UNION ALL 
SELECT 
    Species, Total, HarvestMonthDayYear, 10, 'Archery' 
FROM cte;

TCE없이 :

SELECT Species, HarvestMonthDayYear, SUM(Total) AS Total 
    , CASE WHEN WeaponType IN ('Reg Bow', 'Crossbow') THEN 10 ELSE WeaponID END AS WeaponID 
    , MAX(CASE WHEN WeaponType IN ('Reg Bow', 'Crossbow') THEN 'Archery' ELSE WeaponType END) AS WeaponType 
FROM yourTable 
GROUP BY 
    Species, HarvestMonthDayYear 
    , (CASE WHEN WeaponType IN ('Reg Bow', 'Crossbow') THEN 10 ELSE WeaponID END)
