Introduction:
In order to finish the assignment, we will follow the given instructions to write SQL commands based on the data dictionary provided. We will write SQL commands to retrieve data requested in the data retrieval request.
Answer:
1) List all patients with the last name of “Johnson”.
Based on the given data dictionary, we will write an SQL command to retrieve all patients with the last name of “Johnson”.
SELECT * FROM Patient WHERE LName = ‘Johnson’;
This SQL command will retrieve all the patients with the last name of “Johnson” from the Patient table.
2) List all patients who are female.
Similarly, using the data dictionary provided, we will write an SQL command to retrieve all patients who are female.
SELECT * FROM Patient WHERE Gender = ‘F’;
This SQL command will retrieve all the female patients from the Patient table.
3) List all patient last names and the medical record number of each.
Lastly, we will write an SQL command to retrieve all the patient last names and the medical record number of each.
SELECT LName, MR# FROM Patient;
This SQL command will retrieve all the patient last names and the medical record number of each from the Patient table.
