1. Can I create tables and insert data in this online MariaDB compiler?
Yes. You can use standard supported MariaDB SQL statements to create tables and add records.
For example:
CREATE TABLE students (
id INT PRIMARY KEY,
name VARCHAR(100),
age INT
);
INSERT INTO students (id, name, age)
VALUES
(1, 'Alice', 21),
(2, 'Bob', 23),
(3, 'Charlie', 20);
SELECT * FROM students;
Click Run to execute the statements and view the query results in the Output screen.
2. Is MariaDB syntax the same as MySQL?
MariaDB and MySQL share a large amount of common SQL syntax, so basic statements such as CREATE, INSERT, SELECT, UPDATE, and DELETE often look the same.
For example:
SELECT name, age
FROM students
WHERE age >= 21
ORDER BY age DESC;
However, MariaDB and MySQL are separate database systems and can differ in specific functions, data types, SQL features, storage behavior, and version-dependent functionality. For reliable testing, write queries according to the MariaDB version configured by the online runner.
3. Do I need to install MariaDB Server on my computer to use this tool?
No. You can use this Online MariaDB Compiler / SQL Runner directly from your browser without installing MariaDB Server or a desktop database client for supported SQL exercises.
A local or hosted MariaDB server may still be necessary for production applications, persistent databases, user management, backups, large datasets, external connections, or advanced server configuration.
4. How do I run a basic SELECT query in this MariaDB SQL Runner?
After creating a table and adding data, use SELECT to retrieve the records you need.
SELECT *
FROM products;
You can retrieve specific columns:
SELECT name, price
FROM products;
Or filter the results:
SELECT name, price
FROM products
WHERE price > 1000
ORDER BY price DESC;
Enter the query in the Code Editor, click Run, and review the returned rows in the Output screen.
