无法正确获取sql查询中的计数

sql sql-server

无法正确获取sql查询中的计数,sql,sql-server,Sql,Sql Server,我有这样一个问题： SELECT T_BOE_Stock_Detail.itemCode, T_Master_Item.itemName as Description, T_Master_Item.categoryCode as Category, sum(T_BOE_Stock_Detail.qty - T_BOE_Stock_Detail.ReservedQty) As Qty, SUM(CASE WHEN DOCTYPE = 'GOOD' THEN 1 ELSE 0 END ) Goo

我有这样一个问题：

SELECT T_BOE_Stock_Detail.itemCode, T_Master_Item.itemName as Description,
T_Master_Item.categoryCode as Category, 
sum(T_BOE_Stock_Detail.qty - T_BOE_Stock_Detail.ReservedQty) As Qty,
SUM(CASE WHEN DOCTYPE = 'GOOD' THEN 1 ELSE 0 END  ) Good,
SUM(CASE WHEN DOCTYPE = 'DEFECTIVE' THEN 1 ELSE 0 END) Defective 
FROM T_BOE_Stock_Detail 
LEFT OUTER JOIN T_Master_Item ON T_BOE_Stock_Detail.itemCode = T_Master_Item.itemCode
WHERE T_BOE_Stock_Detail.qty - T_BOE_Stock_Detail.ReservedQty > 0
group by T_BOE_Stock_Detail.itemCode, T_Master_Item.itemName,T_Master_Item.categoryCode
having sum(T_BOE_Stock_Detail.qty - T_BOE_Stock_Detail.ReservedQty) > 0 
order by T_Master_Item.categoryCode, T_BOE_Stock_Detail.itemCode

Itemcode    description   category   qty    good    defective
661-00060   Logic Board                4     2           1

select itemCode,qty,ReservedQty,DOCTYPE from T_BOE_Stock_Detail where itemCode='661-00060' and qty-ReservedQty >0

    Itemcode    description   category   qty    good    defective
    661-00060   Logic Board                4     3           1

我的想法是这样的：

SELECT T_BOE_Stock_Detail.itemCode, T_Master_Item.itemName as Description,
T_Master_Item.categoryCode as Category, 
sum(T_BOE_Stock_Detail.qty - T_BOE_Stock_Detail.ReservedQty) As Qty,
SUM(CASE WHEN DOCTYPE = 'GOOD' THEN 1 ELSE 0 END  ) Good,
SUM(CASE WHEN DOCTYPE = 'DEFECTIVE' THEN 1 ELSE 0 END) Defective 
FROM T_BOE_Stock_Detail 
LEFT OUTER JOIN T_Master_Item ON T_BOE_Stock_Detail.itemCode = T_Master_Item.itemCode
WHERE T_BOE_Stock_Detail.qty - T_BOE_Stock_Detail.ReservedQty > 0
group by T_BOE_Stock_Detail.itemCode, T_Master_Item.itemName,T_Master_Item.categoryCode
having sum(T_BOE_Stock_Detail.qty - T_BOE_Stock_Detail.ReservedQty) > 0 
order by T_Master_Item.categoryCode, T_BOE_Stock_Detail.itemCode

Itemcode    description   category   qty    good    defective
661-00060   Logic Board                4     2           1

select itemCode,qty,ReservedQty,DOCTYPE from T_BOE_Stock_Detail where itemCode='661-00060' and qty-ReservedQty >0

    Itemcode    description   category   qty    good    defective
    661-00060   Logic Board                4     3           1

但是如果我写一个单独的查询，像这样：

SELECT T_BOE_Stock_Detail.itemCode, T_Master_Item.itemName as Description,
T_Master_Item.categoryCode as Category, 
sum(T_BOE_Stock_Detail.qty - T_BOE_Stock_Detail.ReservedQty) As Qty,
SUM(CASE WHEN DOCTYPE = 'GOOD' THEN 1 ELSE 0 END  ) Good,
SUM(CASE WHEN DOCTYPE = 'DEFECTIVE' THEN 1 ELSE 0 END) Defective 
FROM T_BOE_Stock_Detail 
LEFT OUTER JOIN T_Master_Item ON T_BOE_Stock_Detail.itemCode = T_Master_Item.itemCode
WHERE T_BOE_Stock_Detail.qty - T_BOE_Stock_Detail.ReservedQty > 0
group by T_BOE_Stock_Detail.itemCode, T_Master_Item.itemName,T_Master_Item.categoryCode
having sum(T_BOE_Stock_Detail.qty - T_BOE_Stock_Detail.ReservedQty) > 0 
order by T_Master_Item.categoryCode, T_BOE_Stock_Detail.itemCode

Itemcode    description   category   qty    good    defective
661-00060   Logic Board                4     2           1

select itemCode,qty,ReservedQty,DOCTYPE from T_BOE_Stock_Detail where itemCode='661-00060' and qty-ReservedQty >0

    Itemcode    description   category   qty    good    defective
    661-00060   Logic Board                4     3           1

我的想法是这样的：

SELECT T_BOE_Stock_Detail.itemCode, T_Master_Item.itemName as Description,
T_Master_Item.categoryCode as Category, 
sum(T_BOE_Stock_Detail.qty - T_BOE_Stock_Detail.ReservedQty) As Qty,
SUM(CASE WHEN DOCTYPE = 'GOOD' THEN 1 ELSE 0 END  ) Good,
SUM(CASE WHEN DOCTYPE = 'DEFECTIVE' THEN 1 ELSE 0 END) Defective 
FROM T_BOE_Stock_Detail 
LEFT OUTER JOIN T_Master_Item ON T_BOE_Stock_Detail.itemCode = T_Master_Item.itemCode
WHERE T_BOE_Stock_Detail.qty - T_BOE_Stock_Detail.ReservedQty > 0
group by T_BOE_Stock_Detail.itemCode, T_Master_Item.itemName,T_Master_Item.categoryCode
having sum(T_BOE_Stock_Detail.qty - T_BOE_Stock_Detail.ReservedQty) > 0 
order by T_Master_Item.categoryCode, T_BOE_Stock_Detail.itemCode

Itemcode    description   category   qty    good    defective
661-00060   Logic Board                4     2           1

select itemCode,qty,ReservedQty,DOCTYPE from T_BOE_Stock_Detail where itemCode='661-00060' and qty-ReservedQty >0

    Itemcode    description   category   qty    good    defective
    661-00060   Logic Board                4     3           1

我的预期输出如下：

SELECT T_BOE_Stock_Detail.itemCode, T_Master_Item.itemName as Description,
T_Master_Item.categoryCode as Category, 
sum(T_BOE_Stock_Detail.qty - T_BOE_Stock_Detail.ReservedQty) As Qty,
SUM(CASE WHEN DOCTYPE = 'GOOD' THEN 1 ELSE 0 END  ) Good,
SUM(CASE WHEN DOCTYPE = 'DEFECTIVE' THEN 1 ELSE 0 END) Defective 
FROM T_BOE_Stock_Detail 
LEFT OUTER JOIN T_Master_Item ON T_BOE_Stock_Detail.itemCode = T_Master_Item.itemCode
WHERE T_BOE_Stock_Detail.qty - T_BOE_Stock_Detail.ReservedQty > 0
group by T_BOE_Stock_Detail.itemCode, T_Master_Item.itemName,T_Master_Item.categoryCode
having sum(T_BOE_Stock_Detail.qty - T_BOE_Stock_Detail.ReservedQty) > 0 
order by T_Master_Item.categoryCode, T_BOE_Stock_Detail.itemCode

Itemcode    description   category   qty    good    defective
661-00060   Logic Board                4     2           1

select itemCode,qty,ReservedQty,DOCTYPE from T_BOE_Stock_Detail where itemCode='661-00060' and qty-ReservedQty >0

    Itemcode    description   category   qty    good    defective
    661-00060   Logic Board                4     3           1

我想取好的数量和坏的数量之和？那么如何重新编写查询。

您在顶部查询中的行：

SUM(CASE WHEN DOCTYPE = 'GOOD' THEN 1 ELSE 0 END  ) Good,
SUM(CASE WHEN DOCTYPE = 'DEFECTIVE' THEN 1 ELSE 0 END) Defective

它是对

DOCTYPE='GOOD'

或

DOCTYPE='DEFECTIVE'

的行数求和

您需要

DOCTYPE='GOOD'

和

DOCTYPE='DEFECTIVE'

的

quaty

数量。此外，根据您的“总计”数量行，您可能希望减去任何

预留数量
尝试将这些行替换为：
SUM(CASE WHEN DOCTYPE = 'GOOD' THEN qty - ReservedQty ELSE 0 END  ) Good,
SUM(CASE WHEN DOCTYPE = 'DEFECTIVE' THEN qty - ReservedQty ELSE 0 END) Defective

您在顶部查询中的行：
SUM(CASE WHEN DOCTYPE = 'GOOD' THEN 1 ELSE 0 END  ) Good,
SUM(CASE WHEN DOCTYPE = 'DEFECTIVE' THEN 1 ELSE 0 END) Defective

它是对DOCTYPE='GOOD'
或DOCTYPE='DEFECTIVE'
的行数求和
您需要DOCTYPE='GOOD'
和DOCTYPE='DEFECTIVE'
的quaty
数量。此外，根据您的“总计”数量行，您可能希望减去任何预留数量
尝试将这些行替换为：
SUM(CASE WHEN DOCTYPE = 'GOOD' THEN qty - ReservedQty ELSE 0 END  ) Good,
SUM(CASE WHEN DOCTYPE = 'DEFECTIVE' THEN qty - ReservedQty ELSE 0 END) Defective

不添加1，而是添加tbsd.QTY-tbsd.RESERVEDQTY
：
SELECT 
    tbsd.ITEMCODE, 
    tmi.ITEMNAME AS DESCRIPTION,
    tmi.CATEGORYCODE AS CATEGORY, 
    SUM(tbsd.QTY - tbsd.RESERVEDQTY) AS QTY,
    SUM(CASE WHEN DOCTYPE = 'GOOD' THEN tbsd.QTY - tbsd.RESERVEDQTY ELSE 0 END) AS GOOD,
    SUM(CASE WHEN DOCTYPE = 'DEFECTIVE' THEN tbsd.QTY - tbsd.RESERVEDQTY ELSE 0 END) AS DEFECTIVE 
FROM T_BOE_STOCK_DETAIL tbsd
LEFT OUTER JOIN T_MASTER_ITEM 
    ON tbsd.ITEMCODE = tmi.ITEMCODE
WHERE 
    tbsd.QTY - tbsd.RESERVEDQTY > 0
GROUP BY 
    tbsd.ITEMCODE, 
    tmi.ITEMNAME,
    tmi.CATEGORYCODE
HAVING SUM(tbsd.qty - tbsd.ReservedQty) > 0 
ORDER BY 
    tmi.categoryCode,
    tbsd.itemCode  

作为旁注，请为表格添加别名以增加可读性。
添加tbsd.QTY-tbsd.RESERVEDQTY
，而不是添加1:
SELECT 
    tbsd.ITEMCODE, 
    tmi.ITEMNAME AS DESCRIPTION,
    tmi.CATEGORYCODE AS CATEGORY, 
    SUM(tbsd.QTY - tbsd.RESERVEDQTY) AS QTY,
    SUM(CASE WHEN DOCTYPE = 'GOOD' THEN tbsd.QTY - tbsd.RESERVEDQTY ELSE 0 END) AS GOOD,
    SUM(CASE WHEN DOCTYPE = 'DEFECTIVE' THEN tbsd.QTY - tbsd.RESERVEDQTY ELSE 0 END) AS DEFECTIVE 
FROM T_BOE_STOCK_DETAIL tbsd
LEFT OUTER JOIN T_MASTER_ITEM 
    ON tbsd.ITEMCODE = tmi.ITEMCODE
WHERE 
    tbsd.QTY - tbsd.RESERVEDQTY > 0
GROUP BY 
    tbsd.ITEMCODE, 
    tmi.ITEMNAME,
    tmi.CATEGORYCODE
HAVING SUM(tbsd.qty - tbsd.ReservedQty) > 0 
ORDER BY 
    tmi.categoryCode,
    tbsd.itemCode

亲爱的先生，我们必须添加保留数量，而不是数量。我刚刚修改了答案。：-）尊敬的先生，我们必须添加保留数量，而不是数量。我刚刚修改了答案。：-）谢谢。这对我来说很有用我会非常感谢你的谢谢。这对我来说很有用1.我将非常感谢你
