如何从SQL Server中列出结果为空或空数据？

Question

如何列出不是（null = 0）的产品？

STHAR表

id  STHAR_GCKOD  STHAR_GCMIK 
------------------------------------------------ 
1    NULL    NULL 
99    G     2 
99    C     2 
1525   G     3 
1525   C     2 
------------------------------------------------ 

NOTE: G = (+)/C = (-) 

结果

ID 1;  Not found in result, i want to found in result (TOTAL : 0) 
ID 99; TOTAL : 0 
ID 1525; TOTAL : 1 

我的代码：

SELECT 
    B.STOK_KODU, B.STOK_ADI, B.URETICI_KODU, B.KOD_1, 
    SUM(CASE A.STHAR_GCKOD 
     WHEN 'G' THEN STHAR_GCMIK 
     ELSE - STHAR_GCMIK 
     END) BAKIYE 
FROM 
    LSTHAR A 
RIGHT OUTER JOIN 
    TBLSTSABIT B ON B.STOK_KODU=A.STOK_KODU 
GROUP BY 
    B.STOK_KODU, B.STOK_ADI, B.URETICI_KODU, B.KOD_1 
HAVING 
    SUM(CASE A.STHAR_GCKOD WHEN 'G' THEN STHAR_GCMIK 
          ELSE - STHAR_GCMIK END) < B.KOD_6 
ORDER BY 
    B.STOK_KODU ASC 

找不到结果列表为空或空的数据，

让事实结果列表，我想

可能吗？

谢谢。

试试这个

SELECT 
    B.STOK_KODU, B.STOK_ADI, B.URETICI_KODU, B.KOD_1, 
    SUM(CASE A.STHAR_GCKOD 
     WHEN 'G' THEN STHAR_GCMIK 
     ELSE ISNULL(- STHAR_GCMIK,0) END) 
     END) BAKIYE 
FROM 
    LSTHAR A 
RIGHT OUTER JOIN 
    TBLSTSABIT B ON B.STOK_KODU=A.STOK_KODU 
GROUP BY 
    B.STOK_KODU, B.STOK_ADI, B.URETICI_KODU, B.KOD_1 
HAVING 
    SUM(CASE A.STHAR_GCKOD WHEN 'G' THEN STHAR_GCMIK 
          ELSE ISNULL(- STHAR_GCMIK,0) END) < B.KOD_6 
ORDER BY 
    B.STOK_KODU ASC 

编辑：不知道为什么会得到错误信息。然而，在你的原始查询没有得到NULL值的问题是低于

CASE A.STHAR_GCKOD 
     WHEN 'G' THEN STHAR_GCMIK 
     ELSE - STHAR_GCMIK 
     END 

的CASE statument你也可以试试这个，这更清晰

CASE WHEN A.STHAR_GCKOD = 'G' THEN STHAR_GCMIK 
    WHEN A.STHAR_GCKOD = 'C' THEN - STHAR_GCMIK 
    WHEN A.STHAR_GCKOD IS NULL THEN 0 
END
