Oracle Database SQL Expert Sample Questions:

Question #1
View the Exhibit and examine the details of the PRODUCT_INFORMATION table.
You have the requirement to display PRODUCT_NAME and LIST_PRICE from the table where the CATEGORYJD column has values 12 or 13, and the SUPPLIER_ID column has the value 102088. You executed the following SQL statement:
SELECT product_name, list_price FROM product_information WHERE (category_id = 12 AND category_id = 13) AND supplier_id = 102088;
Which statement is true regarding the execution of the query?

A. It would execute and the output would display the desired result.
B. It would not execute because the same column has been used in both sides of the AND logical operator to form the condition.
C. It would execute but the output would return no rows.
D. It would not execute because the entire WHERE clause condition is not enclosed within the parentheses.

Question #2
View the Exhibit and examine the description of the ORDERS table.
Which two WHERE clause conditions demonstrate the correct usage of conversion functions?
(Choose two.)

A. WHERE order_date IN (TO_DATE('Oct 21 2003','Mon DD YYYY"), TO_CHAR('NOV 21 2003','Mon DD YYYY"))
B. WHERE TO_CHAR(order_date,'MON DD YYYY) = 'JAN 20 2003'
C. WHERE order_date > TO_CHAR(ADD_MONTHS(SYSDATE,6),'MON DD YYYY")
D. WHERE order_date > TO_DATE('JUL 10 2006','MON DD YYYY)

Question #3
View the Exhibit and examine the description of the EMPLOYEES table.
You want to know the EMPLOYEE_ID and FIRST_NAME of all the records in the EMPLOYEES table wherein the JOBJD column has ST_CLERK or ST_MAN values, the DEPARTMENT_ID column has value 30, and the SALARY column has a value greater than 3,000.
Which SOL statement would get you the desired result?

A. SELECT employee_id, first_name
FROM employees
WHERE (job_id like '%MAN' OR job_id like '%CLERK')
AND department_id = 30 AND salary > 3000;
B. SELECT employee_id, first_name
FROM employees
WHERE (job_id like '%MAN' AND job_id like ^CLERK")
AND department_id = 30 OR salary > 3000;
C. SELECT employee_id, first_name
FROM employees
WHERE job_id like '%MAN' OR job_id like '%CLERK'
AND (department_id = 30 OR salary > 3000);
D. SELECT employee_id, first_name
FROM employees
WHERE job_id like 'MAN%' OR job_id like 'CLERK%'
AND department_id = 30 AND salary > 3000;

Question #4
View the Exhibit and examine the structure of the LOCATIONS and DEPARTMENTS tables.
Which SET operator should be used in the blank space in the following SQL statement to display the cities that have departments located in them?
SELECT location_id, city
FROM locations
SELECT location_id, city FROM locations JOIN departments USING(location_id);

A. INTERSECT
B. MINUS
C. UNION ALL
D. UNION

Question #5
View the Exhibit and examine the structure of the ORDERS and ORDER_ITEMS tables.
In the ORDERS table, ORDER_ID is the PRIMARY KEY and ORDER_DATE has the DEFAULT
value as SYSDATE.
Evaluate the following statement:
UPDATE orders
SET order_date=DEFAULT
WHERE order_id IN (SELECT order_id FROM order_items
WHERE qty IS NULL);
What would be the outcome of the above statement?

A. The UPDATE statement would not work because the main query and the subquery use different tables.
B. The UPDATE statement would not work because the DEFAULT value can be used only in INSERT statements.
C. The UPDATE statement would change all the ORDER_DATE values to SYSDATE irrespective of what the current ORDER_DATE value is for all orders where QTY is NULL
D. The UPDATE statement would change all ORDER_DATE values to SYSDATE provided the current ORDER_DATE is NOT NULL and QTY is NULL
