SQL錯誤：查詢表達式中的語法錯誤（缺少運算符）

Question

好的，這里是我的代碼。

SELECT Department, COUNT(*) AS CountByTechAndMP
FROM Course
GROUP BY Department
WHERE MPCategory IS NOT NULL AND Technical = true;

我一直在試圖愚弄它，但似乎無法理解。 我覺得我很容易失蹤。

Answer 1

GROUP BY追隨WHERE

SELECT Department, COUNT(*) AS CountByTechAndMP
FROM Course
WHERE MPCategory IS NOT NULL AND Technical = true
GROUP BY Department
