COUNT CASE語句返回不需要的查詢結果

-2

當事件爲「Regular」時，以下查詢正在查找按對象計算的天數，但由於該對象屬於指定日期範圍，查詢結果顯示「Clearance」。有沒有辦法讓這個查詢只顯示日期範圍爲4/10/2017的「Regular」事件通過Today的對象？我已經嘗試了Event NOT IN C或S，並在where子句中移動事件，但獲得了相同的結果。COUNT CASE語句返回不需要的查詢結果

GROUP BY

查詢結果：

Object Days 
Soap 7 
Shampoo ?

期望的結果：

Object Days

使用HAVING語句。 –

我不知道teradata，但是不可能簡單地將這些條件放在WHERE子句中，然後計數（*）？在Oracle中，這個工作正常：'選擇OBJECT，從TEST_MYTABLE01計數（*）WHERE EVENT ='Regular'AND CAL_DATE BETWEEN to_date（'10 .04.2017'，'dd.mm.yyyy'）AND sysdate Group by OBJECT' – Demo

您的結果'Shampoo？'不能被你的查詢返回，它將是'Shampoo 0'。 – dnoeth

嘗試此。

SELECT 
    [OBJECT] 
    ,REGULAR = SUM(CASE WHEN [EVENT] = 'Regular' AND CONVERT(DATE,Cal_Date) BETWEEN '2017-04-10' AND CONVERT(DATE,GETDATE()) THEN 1 ELSE 0 END) 
FROM 
    TABLE1 
GROUP BY 
    [OBJECT]

是REGULAR在OBJECT下應該是不同的東西？它不承認查詢的那一部分。 – Hery0502
