Procedures in SQL

A pre-compiled stored procedure is a logical unit made up of one/more SQL statements (SQL stands for Structured Query Language). The database server saves it as an object. An SQL procedure is a collection of SQL statements and logic that is written and saved to accomplish a specified goal. An SQL procedure consists of a name, a parameter list, and a set of Transact-SQL statements. Stored procedures are stored as named objects in SQL Database Server.

Question

Create access table relationships as shown in the ERD above.

**Entity-Relationship Diagram for a Healthcare Management System**

**Doctor**

- **Doctor Id (PK):** Unique identifier for the doctor.
- **Doctor First Name:** First name of the doctor.
- **Doctor Last Name:** Last name of the doctor.

**Patient**

- **Patient Id (PK):** Unique identifier for the patient.
- **Patient First Name:** First name of the patient.
- **Patient Last Name:** Last name of the patient.

**Appointment**

- **Appointment Date:** Date of the appointment.
- **Appointment Time:** Time of the appointment.
- **Appointment Duration:** Duration of the appointment.
- **Appointment Reason:** Reason for the appointment.
- **Bill Number (FK):** Foreign key that references the Bill entity.
- **Patient Id (FK):** Foreign key that references the Patient entity.
- **Doctor Id (FK):** Foreign key that references the Doctor entity.

**Bill**

- **Bill Number (PK):** Unique identifier for the bill.
- **Bill Date:** Date when the bill was generated.
- **Bill Status:** Current status of the bill (e.g., paid, unpaid).
- **Bill Amount:** Total amount of the bill.

**Diagram Explanation:**
The diagram showcases how different entities in the healthcare management system are related to one another:

1. **Doctor:** Each doctor has a unique `Doctor Id` with their associated first and last names.
2. **Patient:** Each patient has a unique `Patient Id` along with their first and last names.
3. **Appointment:** This entity binds patients with doctors for a specific date, time, and reason for the appointment. Each appointment can be linked to a bill through `Bill Number`, a patient through `Patient Id`, and a doctor through `Doctor Id`.
4. **Bill:** Each bill is uniquely identified by `Bill Number` and contains details like bill date, status, and amount. The bill is connected to the appointments to maintain the financial aspect of the healthcare service.

The interconnecting lines between the entities indicate relational links, where:
- A doctor can have multiple appointments.
- A patient can have multiple appointments.
- An appointment can be associated with one doctor and one patient.
- An appointment can generate a bill.

For this problem create a (temporary) 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 temporary 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 temporary table is up-to-date. You must name your procedure: Written in PostgreSQL
