How to remove '@-prefixed' variable

-
Hi everyone,

I input several commands into the command prompt such as

SET @a = 'test';

I thought by deleting the database the variable will be destroyed but it
turns out that doing a "SELECT @a", it lists a table consisting of 'test'.

Does anyone know how to remove it and list several other variables that
i forgot to remember the names?

Also, what is such thing called so that I know what keyword to use to
google about it.

Thank you in advance.
