-- Some say MySQL already support UUID() function as default, but old versions and MariaDB not!
-- In case you deal with various tables create trigger to insert UUID is not a good solution from 
-- a manteinance point of view.

-- DISCLAIMER 1: For learning purposes only. It is NOT secure setting a fixed value for UUID due to obvious reasons.
-- DISCLAIMER 2: Use char to store UUID is not a wise solution the correct approach is to use BINARY(16). I will keep 
-- the below solution just for very small apps.

CREATE TABLE 'tb_test' (
    'id_test' INT NOT NULL AUTO_INCREMENT PRIMARY KEY
