Premium questions with real-world problems
The Database Administration and SQL test assesses a candidate's knowledge of managing and administering database management systems to store and organize data, along with the knowledge of SQL.
It's an ideal test for pre-employment screening. A good database administrator needs to have knowledge of capacity planning, installation, configuration, database design, migration, performance monitoring, security, troubleshooting, as well as backup and data recovery along with the ability to write SQL queries for the purpose of database administering.
This online test requires candidates to answer multiple-choice and fill the blanks questions about various procedures required for database administration, and to write SQL queries that extract, combine, and manipulate data.
TestDome is trusted by businesses large and small

Free Sample Questions for Database Administration 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.
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
Database Backups
Under a new database backup plan:
- Full backups of the database are taken every 6 hours starting at 00:00.
- Differential backups are taken every 1 hour starting at 01:00, except for intervals of 6 hours (when full backups are taken).
- Transaction/redo log backups are taken every 30 minutes starting at 00:00. The transactional/redo log is reset/cleared after a backup is taken.
Due to a missed scenario during the testing phase, a development error in setting wrong query conditions resulted in the loss of all records from a table at 13:45, which had data prior to the implementation of the backup plan. All further backups were taken as per the mentioned schedule.
Select all the ways to restore the database until 13:45.
(Select all acceptable answers.)
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.
