Cuculating Menge von zwei verschiedenen Tabelle

Question

Ich möchte von zwei die verschiedene Tabelle subtrahieren. Und das Ergebnis ist dritte Tabelle. Dies ist meine SQL-Abfrage:

SELECT 
    a.ma 
    ,a.Ten 
    ,a.Dvt 
    ,ISNULL(SUM(a.Soluong),0) AS Nhap 
    ,ISNULL(SUM(b.Soluong),0) AS Xuat 
    ,(ISNULL(SUM(a.Soluong),0)-ISNULL(SUM(b.Soluong),0)) AS ton 
    ,a.Batch,a.MaKe 
FROM tbNhap a 
    INNER JOIN tbXuat b ON a.ma=b.ma and a.Batch=b.Batch 
GROUP BY 
    a.ma 
    ,a.Ten 
    ,a.Dvt 
    ,a.Batch 
    ,a.MaKe 
HAVING a.Batch LIKE '3217101711' AND a.ma LIKE '11020000000031' 
ORDER BY 
    SUBSTRING(CAST(a.Batch AS varchar(10)), 5, 2) 
    ,SUBSTRING(CAST(a.Batch AS varchar(10)), 3, 2) ASC; 

ich das gleiche Foto angezeigt werden soll. Bitte.

Answer 1

Ich glaube, Sie sollten den Auftrag zwischen SUM und ISNULL ändern, sonst, wenn Sie nur eine NULL in Ihrer Summe haben, die Summe NULL sein wird, und dann wird ISNULL es in 0. Die SELECT ändern würde wie folgt aus:

SELECT 
     a.ma 
    ,a.Ten 
    ,a.Dvt 
    ,SUM(ISNULL(a.Soluong,0)) AS Nhap 
    ,SUM(ISNULL(b.Soluong,0)) AS Xuat 
    ,SUM(ISNULL(a.Soluong,0)-ISNULL(b.Soluong,0)) AS ton 
    ,a.Batch,a.MaKe 
FROM tbNhap a 
    INNER JOIN tbXuat b ON a.ma=b.ma and a.Batch=b.Batch 
GROUP BY 
    a.ma 
    ,a.Ten 
    ,a.Dvt 
    ,a.Batch 
    ,a.MaKe 
HAVING a.Batch LIKE '3217101711' AND a.ma LIKE '11020000000031' 
ORDER BY 
     SUBSTRING(CAST(a.Batch AS varchar(10)), 5, 2) 
    ,SUBSTRING(CAST(a.Batch AS varchar(10)), 3, 2) ASC;

das wird dir geben, was Sie wollen:

DECLARE @tbNhap TABLE 
(
    [id] INT 
    ,[ma] VARCHAR(24) 
    ,[Ten] VARCHAR(24) 
    ,[Dvt] VARCHAR(2) 
    ,[Soluong] INT 
    ,[Batch] VARCHAR(12) 
    ,[Make] VARCHAR(4) 
); 

DECLARE @tbXuat TABLE 
(
    [id] INT 
    ,[ma] VARCHAR(24) 
    ,[Ten] VARCHAR(24) 
    ,[Dvt] VARCHAR(2) 
    ,[Soluong] INT 
    ,[Batch] VARCHAR(12) 
    ,[Make] VARCHAR(4) 
); 

INSERT INTO @tbNhap ([id], [ma], [Ten], [Dvt], [Soluong], [Batch], [Make]) 
VALUES (1, 11020000000031, 'PTZ5S DN', 'PC', 1200, 3714101711, 'Q209') 
     ,(1, 11020000000031, 'PTZ5S DN', 'PC', 1000, 3217101711, 'R202') 
     ,(1, 11020000000031, 'PTZ5S DN', 'PC', 770, 3217101711, 'C203'); 

INSERT INTO @tbXuat ([id], [ma], [Ten], [Dvt], [Soluong], [Batch], [Make]) 
VALUES (1, 11020000000031, 'PTZ5S DN', 'PC', 500, 3217101711, 'R202') 
     ,(1, 11020000000031, 'PTZ5S DN', 'PC', 100, 3217101711, 'C203') 
     ,(1, 11020000000031, 'PTZ5S DN', 'PC', 350, 3217101711, 'C203'); 

SELECT a.ma 
     ,a.Ten 
     ,a.Dvt 
     ,SUM(ISNULL(a.Soluong,0)) AS Nhap 
     ,MAX(b.Xuat) AS Xuat 
     ,SUM(ISNULL(a.Soluong,0))- MAX(b.Xuat) AS ton 
     ,a.Batch 
     ,a.MaKe 
FROM @tbNhap a 
LEFT JOIN 
(
    SELECT ma 
      ,Ten 
      ,Dvt 
      ,Batch 
      ,make 
      ,SUM(ISNULL(Soluong,0)) AS Xuat 
    FROM @tbXuat 
    GROUP BY ma 
      ,Ten 
      ,Dvt 
      ,Batch 
      ,make 
) b 
    ON a.ma=b.ma 
    and a.Batch=b.Batch 
    and a.Make = b.make 
GROUP BY 
    a.ma 
    ,a.Ten 
    ,a.Dvt 
    ,a.Batch 
    ,a.MaKe 
HAVING a.ma LIKE '11020000000031' 
    ORDER BY 
     SUBSTRING(CAST(a.Batch AS varchar(10)), 5, 2) 
    ,SUBSTRING(CAST(a.Batch AS varchar(10)), 3, 2) ASC;
