请求 SubQuery MS Access SQL 代码帮助

Question

我收到此语法错误

查询表达式“Purchases.SUOM_Orders IN (SELECT COUNT(Purchases.SUOM_Orders) FROM Purchases WHERE Purchases.Order_Date>=DATE()-120) subQryCount”中

（缺少运算符）

可能还有其他编译器尚未处理的错误，但如果您发现任何错误，请更正。我感谢您的帮助。忽略“您的文字”部分。我试图将我的代码发布在论坛上，这就是这些部分的原因。

SELECT 
    Inventory.Item_No, Inventory.NDC, Pharmacy.NDC_Desc, 
    ROUND(Inventory.OH_Qty_EA / Pharmacy.McK_PackQty, 0) AS ‘McKesson_OH_Qty’,
    SUM(Purchases.SUOM_Orders / subQryCount.SUOM_Orders) * Pharmacy.Safecor_PackQty * 1.5 / Pharmacy.McK_PackQty AS 'Avg_Par', 
    SUM(Purchases.SUOM_Orders / subQryCount.SUOM_Orders) * Pharmacy.Safecor_PackQty * 1.5 - SUM(Inventory.OH_Qty_EA) / Pharmacy.McK_PackQty AS 'Avg_OrdQty'
FROM 
    (Inventory 
LEFT JOIN 
    Pharmacy ON Inventory.Item_No = Pharmacy.Item_No) 
LEFT JOIN 
    Purchases ON Pharmacy.Item_No = Purchases.Item_No
WHERE 
    Purchases.SUOM_Orders IN (SELECT COUNT(Purchases.SUOM_Orders) 
                              FROM Purchases
                              WHERE Purchases.Order_Date >= DATE() - 120) subQryCount
 GROUP BY 
     Purchases.Item_No ASC
 HAVING 
     Avg_OrdQty > 0;

Answer 1

您的

subQryCount

 条款中不能包含 

WHERE

。

查询要返回的字段名称需要与

SELECT

 查询一起出现。

因此要修复该错误，您需要删除

subQryCount

。这是您更新的 SQL：

SELECT 
    Inventory.Item_No, Inventory.NDC, Pharmacy.NDC_Desc, 
    ROUND(Inventory.OH_Qty_EA / Pharmacy.McK_PackQty, 0) AS ‘McKesson_OH_Qty’,
    SUM(Purchases.SUOM_Orders / subQryCount.SUOM_Orders) * Pharmacy.Safecor_PackQty * 1.5 / Pharmacy.McK_PackQty AS 'Avg_Par', 
    SUM(Purchases.SUOM_Orders / subQryCount.SUOM_Orders) * Pharmacy.Safecor_PackQty * 1.5 - SUM(Inventory.OH_Qty_EA) / Pharmacy.McK_PackQty AS 'Avg_OrdQty'
FROM 
    Inventory 
LEFT JOIN 
    Pharmacy ON Inventory.Item_No = Pharmacy.Item_No
LEFT JOIN 
    Purchases ON Pharmacy.Item_No = Purchases.Item_No
WHERE 
    Purchases.SUOM_Orders IN (SELECT COUNT(Purchases.SUOM_Orders) 
                              FROM Purchases
                              WHERE Purchases.Order_Date >= DATE() - 120)
 GROUP BY 
     Purchases.Item_No ASC
 HAVING 
     Avg_OrdQty > 0;
