SQL選擇那裏是隻有一個日期

目前此查詢：SQL選擇那裏是隻有一個日期

SELECT  InvoiceNumber, CustomerCode, Amount, InvoiceDate 
FROM   Invoice

aaa, 111, 5, 07/12/2009 
bbb, 111, 5, 07/11/2009 
ccc, 222, 5, 07/12/2009

不過，我想寫：Where date = '07/12/2009'，但我只想要返回的結果那裏客戶只有一張發票...

因此，客戶代碼222將被退回，但111不會，因爲111已經有前幾個月的發票....

希望你能幫助！：d

哪個RDBMS？ MySQL，SQL Server，Oracle等？ – MartW 2009-12-18 12:25:09

Sql服務器。下面沒有一個似乎在工作，但試圖找出它 – Will 2009-12-18 12:31:36

你可以給出更多的細節，預期的輸出是什麼？我看到3個答案似乎滿足我對您的要求的理解。 – MartW 2009-12-18 12:40:08

試試這個萌芽

SELECT  InvoiceNumber, CustomerCode, Amount, InvoiceDate, (SELECT count(*) FROM Invoice b WHERE a.CustomerCode=b.CustomerCode AND InvoiceDate = '07/12/2009') as count 
FROM   Invoice a 
Where InvoiceDate = '07/12/2009' 
HAVING count = 1

這應該這樣做：

SELECT 
    InvoiceNumber, CustomerCode, Amount, InvoiceDate 
FROM 
    Invoice 
WHERE 
    COUNT(id) = 1 AND InvoiceDate = '07/12/2009' 
GROUP BY 
    InvoiceDate

聚合可能不會出現在WHERE子句中，除非它位於包含在HAVING子句或選擇列表中的子查詢中，並且要聚合的列是外部引用。 – 2009-12-18 18:24:03

試試這個：

SELECT  InvoiceNumber, CustomerCode, Amount, InvoiceDate 
FROM  Invoice AS Inv 
INNER JOIN 
(
    SELECT CustomerCode 
    FROM Invoice 
    GROUP BY CustomerCode 
    HAVING COUNT(*) = 1 
) AS base 
ON  Inv.CustomerCode = base.CustomerCode 
WHERE InvoiceDate = '07/12/2009'

DECLARE @DateParam datetime 
SELECT @DateParam = Convert(datetime, '07/12/2009', 103) 

SELECT InvoiceNumber, CustomerCode, Amount, InvoiceDate 
FROM Invoice 
INNER JOIN (SELECT CustomerCode 
    FROM Invoice 
    GROUP BY CustomerCode 
    HAVING Count(*) = 1) AS InvoiceCount ON Invoice.CustomerCode = InvoiceCount.CustomerCode 
WHERE InvoiceDate = @DateParam

這將返回的任何地方與invoiceDate等於@DateParam，並且只有一張發票對於整個發票表格中的客戶。

SELECT i.InvoiceNumber, i.CustomerCode, i.Amount, i.InvoiceDate 
FROM  Invoice i 
WHERE i.InvoiceDate = '7/12/2009' 
AND i.InvoiceNumber IN (
    SELECT MAX(InvoiceNumber) 
    FROM Invoice  
    GROUP BY CustomerCode 
    HAVING COUNT(*) = 1

除非您使用聚合，否則不能在您的子查詢的選擇列表中放入InvoiceNumber。 MAX（發票號碼）將工作。 – 2009-12-18 18:27:23

你可以嘗試這樣的事情

DECLARE @Table TABLE(
     InvoiceNumber VARCHAR(10), 
     CustomerCode VARCHAR(10), 
     Amount FLOAT, 
     InvoiceDate DATETIME 
) 

INSERT INTO @Table (InvoiceNumber,CustomerCode,Amount,InvoiceDate) SELECT 'aaa', '111', 5, '07/12/2009' 
INSERT INTO @Table (InvoiceNumber,CustomerCode,Amount,InvoiceDate) SELECT 'bbb', '111', 5, '07/11/2009' 
INSERT INTO @Table (InvoiceNumber,CustomerCode,Amount,InvoiceDate) SELECT 'ccc', '222', 5, '07/12/2009' 

SELECT t.* 
FROM @Table t INNER JOIN 
     (
      SELECT CustomerCode 
      FROM @Table 
      GROUP BY CustomerCode 
      HAVING COUNT(CustomerCode) = 1 
     ) s ON t.CustomerCode = s.CustomerCode 
WHERE t.InvoiceDate = '07/12/2009'

至於建議，這一次似乎下SQLSERVER不被接受

SELECT * 
FROM Invoice i 
INNER JOIN (
    SELECT CustomerCode, InvoiceDate 
    FROM Invoice 
    WHERE InvoiceDate='07/12/2009' 
    GROUP BY CustomerCode 
    HAVING COUNT(CustomerCode)=1 
) grp ON (i.CustomerCode=grp.CustomerCode AND i.InvoiceDate=grp.InvoiceDate)

，或者如果發票號是唯一的

SELECT * 
FROM Invoice i 
INNER JOIN (
    SELECT InvoiceNumber 
    FROM Invoice 
    WHERE InvoiceDate='07/12/2009' 
    GROUP BY CustomerCode 
    HAVING COUNT(CustomerCode)=1 
) grp ON (i.InvoiceNumber =grp.InvoiceNumber)

這將返回具有多個發票的客戶，因爲WHERE子句在GROUP BY之前過濾結果。 – 2009-12-18 18:25:15

是的，我忘記了最後一個的日期 – Patrick 2009-12-18 18:29:04

如果發票是唯一的，我添加了另一個 – Patrick 2009-12-18 18:38:00

SELECT 
    MAX(InvoiceNumber) AS InvoiceNumber 
,CustomerCode 
,MAX(Amount) AS Amount 
,MAX(InvoiceDate) AS InvoiceDate 
FROM Invoice 
GROUP BY CustomerCode 
HAVING COUNT(*) = 1 
    AND MAX(InvoiceDate) = '07/12/2009'
