4. For this problem create a table called instructor_course_nums. Write a procedure that accepts an instructor ID as input. The procedure calculates the total number of course sections taught by that instructor, and adds a tuple to the instructor_course_nums table consisting of the instructors ID number, name, and total courses taught - call these attributes: ID, name, and tot_courses. If the instructor already has an entry in the table, then the procedure makes sure the total number of courses taught in the instructor_course_nums table is up-to-date. You must name your procedure: __insCourseNumsProc

Question
Hi,
I am looking for some help to solve this question. I cannot figure out how to solve it and the code below is all I have.
Please be advised I am using PostgreSQL. Thus, I must use LANGUAGE PLPGSLQ as that is what the professor is looking for.
Thank you for your help.
Code
CREATE TABLE instructor_course_nums (ID VARCHAR(25), name VARCHAR(25), tot_courses VARCHAR(25));
CREATE TEMPORARY TABLE instructor_course_nums (
ID VARCHAR(5),
name VARCHAR(20),
tot_courses INTEGER
);
CREATE OR REPLACE PROCEDURE Moreno_03_insCourseNumsProc(INOUT i_ID VARCHAR(5))
LANGUAGE PLPGSQL
