Question is about storing an UUID in MySQL.

Since version 8.0 of mySQL you can use binary(16) with automatic conversion via UUID_TO_BIN/BIN_TO_UUID functions: https://mysqlserverteam.com/mysql-8-0-uuid-support/

Be aware that mySQL has also a fast way to generate UUIDs as primary key:

INSERT INTO t VALUES(UUID_TO_BIN(UUID(), true))
