SQL：使用表的列值作为存储过程的参数

Question

So I want to create a table with two columns. The first column has studentIDs and the other column has GPA for that corresponding student. I have a stored procedure called sp_calculateGPA that looks up student's grades based on their student ID and calculates their GPA.

Can I use the first column value as a parameter for the stored procedure to get the GPA value for the second column? If yes, how can I do that?

Thank you

Answer 1

You can make a stored procedure that takes in @StudentID INT and then does:

SELECT GPA FROM tableName WHERE studentID = @StudentID

If you need to do summing and averaging of the grades you can group by the studentID and use aggregate functions such as SUM and COUNT
