Common Questions About the Oracle 1Z1-047 Exam

What is the Oracle Database SQL Expert exam all about?

The 1Z1-047 exam is the official Oracle exam behind the Other Oracle Certification certification, validating the skills measured by the Oracle Database SQL Expert credential. It sits at the Expert level of the Oracle certification program. It also connects to Oracle Database SQL Fundamentals I (1Z0-051), so the knowledge you build here carries over to those tracks as well.

How many questions are on the 1Z1-047 exam, and how much time do I get?

The 1Z1-047 exam contains 70 questions to be completed within 120 minutes. Before exam day, divide the available time by the question count to work out a comfortable per-question pace, and mark any item that eats into it so you can return later instead of getting stuck. Timed sessions in the Getcertkey test engines make that pacing automatic — run at least two full-length mock exams under the clock so time pressure never becomes the reason you drop points.

What score do I need to pass the 1Z1-047 exam, and what does it cost?

The passing score for the 1Z1-047 exam is Not publicly disclosed (Oracle doesn’t publish exact pass marks), and the official registration fee is Approximately USD 195 (varies by region). Retakes are not discounted — every new attempt means paying the full fee again — so it pays to measure yourself before you book. Work through the 264 practice questions on Getcertkey, sit a timed practice test, and schedule your exam only when your scores are consistently comfortable. That simple habit is the cheapest exam strategy there is.

Are there any prerequisites for the 1Z1-047 exam?

No formal prerequisite, but SQL Fundamentals knowledge recommended Requirements can change when Oracle revises its certification program, so confirm the current eligibility rules on the official exam page before you register.

Oracle Database SQL Expert Sample Questions:

Question #1

Which statement is true regarding the ROLLUP operator specified in the GROUP BY clause of a SQL statement?

A. It produces only the subtotals for the groups specified in the GROUP BY clause.
B. It produces higher-level subtotals, moving in all the directions through the list of grouping columns specified in the GROUP BY clause.
C. It produces higher-level subtotals, moving from right to left through the list of grouping columns specified in the GROUP BY clause.
D. It produces only the grand totals for the groups specified in the GROUP BY clause.

Question #2

View the Exhibit and examine the description of the EMPLOYEES table.
Your company decided to give a monthly bonus of $50 to all the employees who have completed five years in the company. The following statement is written to display the LAST_NAME,
DEPARTMENT_ID, and the total annual salary:
SELECT last_name, department_id, salary+50*12 "Annual Compensation" FROM employees WHERE MONTHS_BETWEEN(SYSDATE, hire_date)/12 >= 5;
When you execute the statement, the "Annual Compensation" is not computed correctly. What changes would you make to the query to calculate the annual compensation correctly?

A. Change the SELECT clause to SELECT last_name, department_id, salary*12+50 "Annual Compensation".
B. Change the SELECT clause to SELECT last_name, department_id, salary+(50*12) "Annual Compensation".
C. Change the SELECT clause to SELECT last_name, department_id, (salary +50)*12 "Annual Compensation".
D. Change the SELECT clause to SELECT last_name, department_id, (salary*12)+50 "Annual Compensation".

Question #3

View the Exhibit and examine the structure of the ORDERS table:
The ORDER_ID column has the PRIMARY KEY constraint and CUSTOMER_ID has the NOT
NULL constraint.
Evaluate the following statement:
INSERT INTO (SELECT order_id.order_date.customer_id FROM ORDERS WHERE order_total
= 1000 WITH CHECK OPTION) VALUES (13, SYSDATE, 101);
What would be the outcome of the above INSERT statement?

A. It would execute successfully and the ORDER_TOTAL column would have the value 1000 inserted automatically in the new row.
B. It would not execute successfully because the ORDER_TOTAL column is not specified in the SELECT list and no value is provided for it.
C. It would not execute successfully because all the columns from the ORDERS table should have been included in the SELECT list and values should have been provided for all the columns.
D. It would execute successfully and the new row would be inserted into a new temporary table created by the subquery.

Question #4

View the Exhibit and examine the description for EMPLOYEES and DEPARTMENTS tables.
Evaluate the following SQL statement:
SELECT e.department_id, e.job_id, d.location_id, sum(e. salary) total FROM employees e JOIN departments d ON e.department_id = d.department_id GROUP BY CUBE (e.department_id, e.job_id, d.location_id);
Which two statements are true regarding the output of this command? (Choose two.)

A. The output would display the total salary for all the JOB_IDs in a department.
B. The output would display the total salary for all the departments.
C. The output would display the grand total of the salary for only the groups specified in the GROUP BY clause.
D. The output would display only the grand total of the salary for all JOB_IDs in a LOCATION_ID.

Question #5

View the Exhibit and examine the data in ORDERS and ORDER_ITEMS tables.
You need to create a view that displays the ORDER ID, ORDER_DATE, and the total number of
items in each order.

Which CREATE VIEW statement would create the view successfully?

A. CREATE OR REPLACE VIEW ord_vu
AS SELECT o.order_id, o.order_date, COUNT(i.line_item_id)
FROM orders o JOIN order_items i ON (o.order_id = i.order_id)
GROUP BY o.order_id,o.order_date;
B. CREATE OR REPLACE VIEW ord_vu
AS SELECT o.order_id, o.order_date, COUNT(i.line_item_id)ll' NO OF ITEMS'
FROM orders o JOIN order_items i
ON (o.order_id = i.order_id)
GROUP BY o.order_id,o.order_date
WITH CHECK OPTION;
C. CREATE OR REPLACE VIEW ord_vu
AS SELECT o.order_id, o.order_date, COUNT(i.line_item_id)
"NO OF ITEMS"
FROM orders o JOIN order_items i
ON (o.order_id = i.order_id)
GROUP BY o.order_id,o.order_date;
D. CREATE OR REPLACE VIEW ord_vu (order_id,order_date)
AS SELECT o.order_id, o.order_date, COUNT(i.line_item_id)
"NO OF ITEMS"
FROM orders o JOIN order_items i
ON (o.order_id = i.order_id)
GROUP BY o.order_id,o.order_date;
