繰り返し値を1回だけ表示し、繰り返す場合は ' - 'を表示する方法

Question

各PolicyNumberに対して同じ値を取得するサブクエリがあります。どのように私は繰り返された値を ' - 'で置き換えることができ、それは各方針の最上列に1つだけ表示しますか？ は今のところ私はこの持っている： をしかし、私はこのような何か必要があります：あなたはSQLでそれをやってみたかった場合は、このような何かを行うことができます（あなたはおそらくそれはかなり醜いべきではありません）

SELECT 
    -------------/* GrossPremium*/ 

      (SELECT ISNULL(SUM(tblFin_InvoiceDetails.AmtBilled), 0) 
       FROM tblFin_InvoiceDetails WITH (NOLOCK) 
       WHERE (tblFin_InvoiceDetails.ChargeType = 'P') 
       AND (tblFin_InvoiceDetails.InvoiceNum = INV.InvoiceNum)) 
       AS GrossPremium 

--------------/*CompanyCommissionPercentage*/ 

       ,((SELECT ISNULL(SUM(tblFin_InvoiceDetails.MGAAmt), 0)

さてあなたは、あなたの完全なクエリとテーブルのスキーマ言及していないので、私は2つの単純なexample.Ifであなたの答えを与えるあなたが欲しいのは、あなたの繰り返し値が（応じて、列名を変更してくださいこのクエリをたどる-と交換しますあなたのニーズに合わせて）。 既存TABLE選択したい場合：サブクエリを使用するための

    select S1.[ProductID], row_number() over (partition by S1.[ProductID] order by S1.[ProductID]) as seqnum 
    from (SELECT [SalesID],[ProductID] FROM [Sales]) AS S1 --Replace 'SELECT [ProductID] FROM [Sales]' with your Subquery and change the column accordingly 
) 
SELECT 
(case when seqnum = 1 then [ProductID] ELSE '-' end) as [ProductID] 
FROM ts

Answer 2

をLAG（）を使用します。これは、各ポリシー番号のレコードをソートするために使用できるフィールドを持つことに依存します。私の下のダミーのデータでは、これを行うRecordIDというフィールドが含まれています。

SELECT 
    PolicyNumber 
    ,CASE 
     WHEN LAG(GrossPremium) OVER(PARTITION BY PolicyNumber ORDER BY RecordID) IS NULL 
     THEN CAST(GrossPremium AS VARCHAR(MAX)) 
     ELSE '-' 
    END GrossPremium 
    ,CASE 
     WHEN LAG(CompanyComissionPercentage) OVER(PARTITION BY PolicyNumber ORDER BY RecordID) IS NULL 
     THEN CAST(CompanyComissionPercentage AS VARCHAR(MAX)) 
     ELSE '-' 
    END CompanyComissionPercentage 
    ,CASE 
     WHEN LAG(RemitterCommissionPercentage) OVER(PARTITION BY PolicyNumber ORDER BY RecordID) IS NULL 
     THEN CAST(RemitterCommissionPercentage AS VARCHAR(MAX)) 
     ELSE '-' 
    END RemitterCommissionPercentage 
    ,CASE 
     WHEN LAG(RemitterCommission) OVER(PARTITION BY PolicyNumber ORDER BY RecordID) IS NULL 
     THEN CAST(RemitterCommission AS VARCHAR(MAX)) 
     ELSE '-' 
    END GrossCommission 
    ,CASE 
     WHEN LAG(RemitterCommission) OVER(PARTITION BY PolicyNumber ORDER BY RecordID) IS NULL 
     THEN CAST(RemitterCommission AS VARCHAR(MAX)) 
     ELSE '-' 
    END GrossCommission 
FROM 
( 
    -- Dummy data 
    SELECT 
      1234 PolicyNumber -- Partition the LAG() on the policy number. 
      ,1 RecordID -- use this to order the LAG() function.
