Premium questions with real-world problems
The Oracle PL/SQL and SQL online test assesses candidates' knowledge of SQL queries, relational database concepts, and specific Oracle PL/SQL features.
It's an ideal test for pre-employment screening. A good database admin or back-end developer working exclusively on an Oracle SQL Server database layer needs to be able to use Oracle's PL/SQL to create custom procedures and objects to interface efficiently with a database.
This online test requires candidates answer multiple-choice questions about PL/SQL, features of the Oracle SQL Engine, and write SQL queries that extract, combine, and manipulate data.

Our sample questions are free for companies to use on a trial plan. See more about our premium questions for paid plans below.
Count Users
Consider the following code:
CREATE OR REPLACE FUNCTION count_users RETURN NUMBER IS user_count NUMBER; BEGIN SELECT COUNT(*) INTO user_count FROM users; RETURN user_count; END; /
Select the statements that are correct.
(Select all acceptable answers.)
Students
Given the following data definition, write a query that returns the number of students whose first name is John. String comparisons should be case sensitive.
TABLE students id INTEGER PRIMARY KEY, firstName VARCHAR(30) NOT NULL, lastName VARCHAR(30) NOT NULL
Couples
Consider the following table definition:
CREATE TABLE couples( id NUMBER PRIMARY KEY NOT NULL, first_name VARCHAR2(50) NOT NULL, last_name VARCHAR2(50) NOT NULL );
Later the following code is executed:
DECLARE husband_id NUMBER; BEGIN SELECT id INTO husband_id FROM couples WHERE first_name = 'John' AND last_name = 'Johnson'; INSERT INTO couples(id, first_name, last_name) VALUES(husband_id + 1, 'Jane', 'Johnson'); END;

Pass/fail grouping
Our tests are designed to put candidates into either the pass group or the fail group so you can find the best candidates faster.
Full customization
We have pre-built tests and questions, but you can customize them however you like. Change the pass/fail scores, time requirements, and more.
Cheating protection
Use tests that solve real-world problems, with no answers that can be easily found online. Because we test performance and skills (not information), we allow the use of online resources, just like in real life. Copy/paste prevention and online proctoring via webcam prevent cheating.
Candidate reporting
Get an overview into the percentage of passes and fails. Then dive deeper into the results of your top candidates to select who goes onto the next phase of hiring.
