#create a table and name it
CREATE TABLE test_name(
#create some vars in the table like id, name, age and etc.

name VARCHAR,
age FLOAT NOT NULL
PRIMARY KEY(id) #define the primary key of the table(primary key is a var that will never be the same in each column in the table it will be "unique" rise up for each column

Creates a new table .
Example: Creates a new table called ‘users’ in the ‘websitesetup’ database.
CREATE TABLE users (
id int,
first_name varchar(255),
surname varchar(255),
address varchar(255),
contact_number int
);
#create a table
CREATE TABLE employees( id INT NOT NULL AUTO_INCREMENT,
first_name VARCHAR(30) NOT NULL,
last_name VARCHAR(30) NOT NULL,
middle_name VARCHAR(30),
age INTEGER NOT NULL,
current_status VARCHAR(100) NOT NULL DEFAULT 'employed',
PRIMARY KEY(id)
);
#fill the table with data
INSERT INTO employees (first_name, last_name, middle_name, age, current_status)
VALUES ('testname','testlastname','testmiddlename', 23, 'Searching');
#view all the data inside the table
SELECT * FROM employees;
