保留所有文本值的计数，而不是我在SQL中提供条件

Question

我有一个非常简单的查询，用于计算“决策”列中“原因取消”的数量。它会继续计算列中的所有文本值，而不仅仅是导致取消。

SELECT Marketics.Case, Count(Marketics.Decision) AS CountOfDecision
FROM Marketics
GROUP BY Marketics.Case
HAVING Count(Marketics.Decision="Cause Cancel");

Answer 1

SELECT Marketics.Case, Count(Marketics.Decision) AS CountOfDecision
FROM Marketics
GROUP BY Marketics.Case
HAVING Count(Marketics.Decision="Cause Cancel") > 0;
