子查询提供了空结果
问题描述：
我有两个表，我想让它的一个子查询，像这样：子查询提供了空结果
SELECT VPL.[Location Code], sum(VPL.Amount) as totaal, V.[Freight-free Limit]
FROM [Verploegen POC$Purch_ Inv_ Line] VPL
JOIN [Verploegen POC$Vendor] V
ON VPL.No_ = V.No_
--WHERE [Buy-from Vendor No_] = '3929' -- is empty??' --'3932' --'3929' --'3923' --'3904' --'3885' --'3820' --'3894'
WHERE VPL.[Buy-from Vendor No_] = '3929' AND VPL.Type = 2 AND [Posting Date] BETWEEN '2016-01-01' AND '2016-12-31'
GROUP BY VPL.[Location Code], V.[Freight-free Limit] --, VPL.[Direct Unit Cost]
但是这给零reuslt。但如果我这样做：
SELECT V.[Freight-free Limit], PL.[Location Code], sum(Amount) as totaal --SUM([Unit Cost])
FROM [Verploegen POC$Vendor] V
FULL JOIN [Verploegen POC$Purch_ Inv_ Line] PL
ON V.No_= PL.No_
WHERE [Buy-from Vendor No_] = '3929' AND Type = 2 AND [Posting Date] BETWEEN '2016-01-01' AND '2016-12-31'
GROUP BY V.[Freight-free Limit], PL.[Location Code]
它给出了这样的结果：
NULL AM 1585.30000000000000000000
NULL DB 1865.91000000000000000000
NULL DL 3652.43000000000000000000
NULL RD 1599.32000000000000000000
NULL ZM 571.54000000000000000000
你看。如果客户订购了一些金额，则客户不需要支付运费。这是propertie：免运费限制]
例如这样的：
SELECT [Freight-free Limit]
FROM [Verploegen POC$Vendor]
WHERE No_ = '3929'
给出的结果是： 350.00000000000000000000
但我不明白的子查询工作。
谢谢。

我有这样的：
SELECT VPL.[Location Code], sum(VPL.Amount) as totaal, VPL.[Buy-from Vendor No_] --, V.[Freight-free Limit]
FROM [Verploegen POC$Purch_ Inv_ Line] VPL
WHERE VPL.[Buy-from Vendor No_] = '3929' AND VPL.Type = 2 AND [Posting Date] BETWEEN '2016-01-01' AND '2016-12-31'
GROUP by VPL.[Location Code], VPL.[Buy-from Vendor No_]--, VPL.[Vendor Item No_]
ORDER BY VPL.[Location Code]
随着结果是这样的：
AM 1585.30000000000000000000 3929
DB 1865.91000000000000000000 3929

ZM 571.54000000000000000000 3929
但如何实现propertie： 免运费限制
答
这是做的伎俩：
use [VERPLOEGEN-NAV2009-LIVE]
SELECT VPL.[Location Code],
SUM(VPL.Amount) AS Total,
V.[Freight-free Limit]
FROM [Verploegen POC$Purch_ Inv_ Line] VPL
JOIN [Verploegen POC$Vendor] V
ON VPL.[Buy-from Vendor No_] = V.No_
--WHERE [Buy-from Vendor No_] = '3929' -- is empty??' --'3932' --'3929' --'3923' --'3904' --'3885' --'3820' --'3894'
WHERE VPL.[Buy-from Vendor No_] = '3929'
AND VPL.Type = 2 AND ([Posting Date] BETWEEN '2016-01-01' AND '2016-12-31')
GROUP BY VPL.[Location Code], V.[Freight-free Limit] --, VPL.[Direct Unit Cost]
我只是用错了propertie
第一个查询默认为'INNER JOIN'表示如果没有匹配，则不会返回任何内容。你可以根据你的表的顺序在'FROM'子句之后使用'LEFT JOIN'或'RIGHT JOIN'。如果您发布表结构，示例数据等，可能会有帮助。 – BJones
嗨，谢谢您的评论。我添加了表 – SavantCode
我不确定哪部分是“子查询”。 – shawnt00
