SQLクエリの概要行

Question

顧客は複数の契約を結ぶことができ、各契約には複数の商品（下の画像ではA〜H）があります。私は各契約の製品数を示す次のクエリを書いた。次にRowNumを使用して、今日に最も近いAgreementとAgreementEndDateを決定します。

しかし、私が返す必要があるのはRowNum = 1です。a）今日に最も近いAgreementEndDate（および関連するAgreementIDとAgreementEffectiveDate）と製品購入の概要。

したがって、ROWNUM 1 =

• AgreementID = 73838545
• AgreementEffectiveDate = 2015年5月28日
• AgreementEndDate = 2018年5月31日
• A = 1
• B = 1
• C = 1
• D = 1
• E = 1
• F = 1
• G = 1
• H = 0

Select 
    LA.* 
from 
    (select 
     CustomerID 
     ,AgreementID 
     ,min(CONVERT(char(10), AgreementEffectiveDate,126)) as 'AgreementEffectiveDate' 
     ,min(CONVERT(char(10), AgreementEndDate,126)) as 'AgreementEndDate' 
     ,(CASE WHEN sum(cast([A Agreement] as float)) >= 1 THEN 1 ELSE 0 END) as 'A Agreement' 
     ,(CASE WHEN sum(cast([B Agreement] as float)) >= 1 THEN 1 ELSE 0 END) as 'B Agreement' 
     ,(CASE WHEN sum(cast([C Agreement] as float)) >= 1 THEN 1 ELSE 0 END) as 'C Agreement' 
     ,(CASE WHEN sum(cast([D Agreement] as float)) >= 1 THEN 1 ELSE 0 END) as 'D Agreement' 
     ,(CASE WHEN sum(cast([E Agreement] as float)) >= 1 THEN 1 ELSE 0 END) as 'E Agreement' 
     ,(CASE WHEN sum(cast([F Agreement] as float)) >= 1 THEN 1 ELSE 0 END) as 'F Agreement' 
     ,(CASE WHEN sum(cast([G Agreement] as float)) >= 1 THEN 1 ELSE 0 END) as 'G Agreement' 
     ,(CASE WHEN sum(cast([H Agreement] as float)) >= 1 THEN 1 ELSE 0 END) as 'H Agreement' 
     ,ROW_NUMBER() OVER(PARTITION BY TPID ORDER BY AgreementEndDate ASC) AS RowNum 
     from LicenseAgreement 
     Group by CustomerID, AgreementID, AgreementEndDate 
     ) LA 
    where TPID = '1789' --and RowNum = 1 
order by RowNum, CustomerID, AgreementID, AgreementEndDate

私は解決策を考え出すことになりました。私はちょうど内部結合を追加しました。私がこれをしたら、すべてがうまくいった。

これは最善の方法ではありませんが、機能します。

Select 
    B.ID 
    ,B.AgreementID 
    ,B.AgreementEffectiveDate 
    ,B.AgreementEndDate 
    ,(CASE WHEN sum(cast(LA.[A Agreement] as float)) >= 1 THEN 1 ELSE 0 END) as 'A Agreement' 
    ,(CASE WHEN sum(cast(LA.[B Agreement] as float)) >= 1 THEN 1 ELSE 0 END) as 'BAgreement' 
    ,(CASE WHEN sum(cast(LA.[C Agreement] as float)) >= 1 THEN 1 ELSE 0 END) as 'C Agreement' 
    ,(CASE WHEN sum(cast(LA.[D Agreement] as float)) >= 1 THEN 1 ELSE 0 END) as 'D Agreement' 
    ,(CASE WHEN sum(cast(LA.[E Agreement] as float)) >= 1 THEN 1 ELSE 0 END) as 'E Agreement' 
    ,(CASE WHEN sum(cast(LA.[F Agreement] as float)) >= 1 THEN 1 ELSE 0 END) as 'F Agreement' 
    ,(CASE WHEN sum(cast(LA.[G Agreement] as float)) >= 1 THEN 1 ELSE 0 END) as 'G Agreement'
