Premium questions with real-world problems
The MySQL and SQL online test assesses candidates' knowledge of SQL queries, relational database concepts, and specific MySQL features.
It's an ideal test for pre-employment screening. A good database admin or back-end developer working exclusively on a MySQL server database needs to be able to use features specific to MySQL to interface efficiently with the database.
This online test requires candidates to answer multiple-choice questions about MySQL, write queries and stored procedures for MySQL, and to write SQL queries that extract, combine, or manipulate data.
TestDome is trusted by businesses large and small

Free Sample Questions for MySQL and SQL Test
Our sample questions are free for companies to use on a trial plan. See more about our premium questions for paid plans below.
Paginate Users
Consider the following table:
CREATE TABLE users (
id BIGINT NOT NULL AUTO_INCREMENT PRIMARY KEY,
username VARCHAR(50) NOT NULL
);
The following query is used to paginate the table:
SELECT * FROM users ORDER BY username LIMIT 5 OFFSET 15;
Select all the true statements about this method of pagination.
(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
Enrollment
A table containing the students enrolled in a yearly course has incorrect data in records with ids between 20 and 100 (inclusive).
TABLE enrollments id INTEGER NOT NULL PRIMARY KEY year INTEGER NOT NULL studentId INTEGER NOT NULL
Write a query that updates the field 'year' of every faulty record to 2015.

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.
