sql

Mọi người ơi, em đang học ngôn ngữ truy vấn sql và cho em hỏi để tạo một store procedure tính điểm trung bình các học viên theo yêu cầu:

--Nhận vào mã một học viên, cho biết điểm trung bình của học viên đó.
--Điểm trung bình được tính trên điểm thi lần thi sau cùng của học viên theo công thức:
--Điểm trung bình = ∑(Điểm * Số tín chỉ) / ∑Số tín chỉ
