Cannot use Parameter in Create User query

[suyecufi suyecufi]

Hello,

I'm trying to use the parameters for the following query:

CREATE USER 'user'@'host' IDENTIFIED BY 'password';

So I'm using a base query

CREATE USER @user@@domain IDENTIFIED BY @password;

but I'm unsuccessful and I get an error on @user@@domain parameter.

What I can do?

Regards
