データベースには、基本的に現在の売上 (dbo_SalesItem) と過去の売上 (dbo_SalesItemHistory) の 2 つのテーブルがあります。各テーブルから一意のベンダー名の数を取得するクエリがありますが、これらを結合して両方のクエリから単一の合計を取得するにはどうすればよいですか?

テーブル内のフィールドは同じです。

SELECT dbo_SalesItem.Vendor AS [Vendor ID], dbo_Vendor.Vendor_Name AS [Vendor Name], Count(*) AS [Count]
FROM (dbo_SalesDoc INNER JOIN dbo_SalesItem ON dbo_SalesDoc.Sales_Doc_Num = dbo_SalesItem.Sales_Doc_Num) INNER JOIN dbo_Vendor ON dbo_SalesItem.Vendor = dbo_Vendor.Vendor_ID
WHERE (((dbo_SalesDoc.Hold_Code)="ITEMLINK" Or (dbo_SalesDoc.Hold_Code)="TKTLINK") AND ((dbo_SalesDoc.Sales_Doc_Num) Like "ORD*"))
GROUP BY dbo_SalesItem.Vendor, dbo_Vendor.Vendor_Name, dbo_SalesDoc.Last_Update_On
HAVING (((dbo_SalesDoc.Last_Update_On)>=DateAdd("d",-90,Date())))
ORDER BY Count(*) DESC;

SELECT dbo_SalesItemHistory.Vendor AS [Vendor ID], dbo_Vendor.Vendor_Name AS [Vendor Name], Count(*) AS [Count]
FROM (dbo_SalesDoc INNER JOIN dbo_SalesItemHistory ON dbo_SalesDoc.Sales_Doc_Num = dbo_SalesItemHistory.Sales_Doc_Num) INNER JOIN dbo_Vendor ON dbo_SalesItemHistory.Vendor = dbo_Vendor.Vendor_ID
WHERE (((dbo_SalesDoc.Hold_Code)="ITEMLINK" Or (dbo_SalesDoc.Hold_Code)="TKTLINK") AND ((dbo_SalesDoc.Sales_Doc_Num) Like "ORD*"))
GROUP BY dbo_SalesItemHistory.Vendor, dbo_Vendor.Vendor_Name, dbo_SalesDoc.Last_Update_On
HAVING (((dbo_SalesDoc.Last_Update_On)>=DateAdd("d",-90,Date())))
ORDER BY Count(*) DESC;

クエリの結果は次のようになります。

Vendor ID    Vendor Name    Count
12345        Big Vendor     1200
23453        Big Vendor      900
43498        Other Vendor    600
98342        This Vendor     500
08943        Small Vendor    100

ありがとう！

UNION ALL2 つの既存のクエリにサブクエリを使用します。ORDER BYただし、その条項は破棄してください。次に、親クエリはGROUP BY、各ベンダーのカウントを合計する にすることができます。

SELECT
    sub.[Vendor ID],
    sub.[Vendor Name],
    Sum(sub.Count) As SumOfCount
FROM
    (
        SELECT dbo_SalesItem.Vendor AS [Vendor ID], dbo_Vendor.Vendor_Name AS [Vendor Name], Count(*) AS [Count]
        FROM (dbo_SalesDoc INNER JOIN dbo_SalesItem ON dbo_SalesDoc.Sales_Doc_Num = dbo_SalesItem.Sales_Doc_Num) INNER JOIN dbo_Vendor ON dbo_SalesItem.Vendor = dbo_Vendor.Vendor_ID
        WHERE (((dbo_SalesDoc.Hold_Code)="ITEMLINK" Or (dbo_SalesDoc.Hold_Code)="TKTLINK") AND ((dbo_SalesDoc.Sales_Doc_Num) Like "ORD*"))
        GROUP BY dbo_SalesItem.Vendor, dbo_Vendor.Vendor_Name, dbo_SalesDoc.Last_Update_On
        HAVING (((dbo_SalesDoc.Last_Update_On)>=DateAdd("d",-90,Date())))
        UNION ALL
        SELECT dbo_SalesItemHistory.Vendor AS [Vendor ID], dbo_Vendor.Vendor_Name AS [Vendor Name], Count(*) AS [Count]
        FROM (dbo_SalesDoc INNER JOIN dbo_SalesItemHistory ON dbo_SalesDoc.Sales_Doc_Num = dbo_SalesItemHistory.Sales_Doc_Num) INNER JOIN dbo_Vendor ON dbo_SalesItemHistory.Vendor = dbo_Vendor.Vendor_ID
        WHERE (((dbo_SalesDoc.Hold_Code)="ITEMLINK" Or (dbo_SalesDoc.Hold_Code)="TKTLINK") AND ((dbo_SalesDoc.Sales_Doc_Num) Like "ORD*"))
        GROUP BY dbo_SalesItemHistory.Vendor, dbo_Vendor.Vendor_Name, dbo_SalesDoc.Last_Update_On
