COUNT CASE语句返回不需要的查询结果

-2

当事件为“Regular”时，以下查询正在查找按对象计算的天数，但由于该对象属于指定日期范围，查询结果显示“Clearance”。有没有办法让这个查询只显示日期范围为4/10/2017的“Regular”事件通过Today的对象？我已经尝试了Event NOT IN C或S，并在where子句中移动事件，但获得了相同的结果。COUNT CASE语句返回不需要的查询结果

查询结果：

期望的结果：

使用HAVING语句。 –

我不知道teradata，但是不可能简单地将这些条件放在WHERE子句中，然后计数（*）？在Oracle中，这个工作正常：'选择OBJECT，从TEST_MYTABLE01计数（*）WHERE EVENT ='Regular'AND CAL_DATE BETWEEN to_date（'10 .04.2017'，'dd.mm.yyyy'）AND sysdate Group by OBJECT' – Demo

您的结果'Shampoo？'不能被你的查询返回，它将是'Shampoo 0'。 – dnoeth

尝试此。

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下应该是不同的东西？它不承认查询的那一部分。 – Hery0502
