Question
plz answer this pl/sql exam question
This question has to do with pl/sql. i had a different answer for this question than the one supposed to be true. I wanna know why I'm wrong:
--------------------------
Examin this code:
CREATE OR REPLACE PROCEDURE insert_dept (p_location_id NUMBER)
IS
v_dept_id NUMBER(4);
BEGIN
INSERT INTO departments
VALUES (5, 'Education', 150, p_location_id);
SELECT department_id
INTO v_dept_id
FROM employees
WHERE employee_id = 99999;
END insert_dept;
/
CREATE OR REPLACE PROCEDURE insert_location (p_location_id NUMBER, p_city VARCHAR2)
IS
BEGIN
INSERT INTO locatoins( location_id, city)
VALUES (p_location_id, p_city);
insert_dept( p_location_id );
END insert_location;
/
You just created the departments, the locations, and the employees table. You did not insert any rows. Next you created both procedures.
You now invoke insert_location procedure using the following command:
EXECUTE insert_location(19, 'San Francisco')
What is the result in this EXECUTE command?
A. The locations, departments and employees tables are empty.
B. The departments table has one row.
The locations and the employees tables are empty.
C. The location table has one row.
The departments and the employees table are empty.
D. The locations table and the departments table both have one row.
The employees table is empty.
Answer: A
--------------------------
Why A?! isn't supposed to be D. Please explain.
p.s, i assure you i have made no mistake in copying the question text. So there are no typos.
