我不知道问题出在哪里。有什么想法吗?我尝试从评分表更新我的 first_q 列。

UPDATE gradings g set g.first_q = 90 FROM gradings
INNER JOIN subjects ss
on ss.subject_id = g.subject_id
INNER JOIN students s
ON s.id = g.student_id
INNER JOIN school_years sy
on sy.id = g.sy_id
INNER JOIN teachers t
on t.id = g.teacher_id
WHERE s.id = 1;
