Solved: create database and grant user rights mariadb

Sure, let’s begin writing about MariaDB, its creation, usage, and user rights management. Here’s how the article could go:

MariaDB is a powerful, robust and scalable open-source relational database system, widely used around the world due to its features and compatibility with MySQL. With MariaDB, you can conveniently manage data in various formats and assign roles and rights to users with ease. This article’s purpose will be to enlighten readers on how they can create a database and manage user rights within MariaDB.

Creating a database in MariaDB

The creation of a database in MariaDB is a simple task, provided you have access to the MariaDB shell and necessary privileges. After logging into MariaDB, the first step involves creating the database. This is done using the CREATE DATABASE command, with the syntax being:

CREATE DATABASE database_name;

Replace ‘database_name’ with the desired name for your database. After you execute this command, MariaDB will create the new database.

Managing User Rights in MariaDB

After creating your database, the next crucial step is managing user rights. MariaDB provides several commands that help in managing user rights from granting all privileges to specific roles. Before assigning roles, ensure that the user exists. If not, you can create a user using the CREATE USER command:

CREATE USER 'new_user'@'localhost' IDENTIFIED BY 'password';

Once you’ve ensured the user exists, you can grant privileges using the GRANT command. The syntax for granting all privileges is:

GRANT ALL PRIVILEGES ON database_name.* TO 'username'@'localhost';

Note: Replace ‘database_name’ with the name of your database and ‘username’ with the user you want to grant privileges.

Once you have executed these commands, it’s important to remember to reload all the privileges using the FLUSH PRIVILEGES command:


Understanding Important MariaDB Functions

MariaDB possesses several built-in functions that can be used for various purposes such as data type conversion, comparison, mathematical calculations etc.

  • CONCAT(): This function is used to concatenate two or more strings.
  • DATE(): It extracts the date part of a date or datetime expression.
  • AVG(): It returns the average value of a specific column.

By effectively understanding and implementing these commands and functions, anyone can administer a MariaDB database efficiently. Database creation and user rights management are crucial skills to have when dealing with MariaDB, offering control over data management and security aspects that are essential in today’s digital world.
