GRANT ACCESS
look this up in order to grant access to new user

SHOW DATABASES
//Displays your current databases

CREATE DATABASE name
//Creates a new database

USE DATABASE name
//Brings you to that Database, should change prompt

CREATE TABLE
look this up in order to see how to create tables

EXAMPLE OF CREATE TABLE:
CREATE TABLE to_do (id INTEGER NOT NULL AUTO_INCREMENT PRIMARY KEY, task VARCHAR(28) NOT NULL) Engine=InnoDB;

SHOW TABLES
Shows databases tables

DESCRIBE name
Shows the properties of the table property

SELECT * FROM table_name;

# To add new users to the mysq.user database log into mariadb as root and then type:

USE mysql; # use the mysql database
SELECT User, Host, plugin FROM mysql.user;

# You will be presented with a display of a basic SQL table with User and plugin columns, below will display the user name under the user column and mysql_native_password under the plugin column.

# From here you can create a new user using the following mySQL command:

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

GRANT ALL PRIVILEGES ON *.* TO user@localhost IDENTIFIED BY 'password';

# To delete a row from a table:
DELETE FROM tablename WHERE parameters; (parameters example: id = 1)

# To export a database and save it as a .sql file:
mysqldump -u username -p current_database_name > sql_file_name.sql

# To import a database from a .sql file:
# Enter mariadb:
mariadb -u username -p
# Enter password
CREATE DATABASE new_database_name;
# Exit mariadb:
\q
mariadb -u username -p new_database_name < sql_file_name.sql
