SQL错误：查询表达式中的语法错误（缺少运算符）

Question

Ok so here my code.

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

I have been trying to fool with it but I just can't seem to get it. I feel like it is something easy that I am just missing.

Answer 1

GROUP BY goes after WHERE

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