why won't my SQL run in vscode? What can I do to fix this?

Question

I am following this tutorial for SQL: https://www.youtube.com/watch?v=Cz3WcZLRaWc

I followed all the instructions, but when I click run I get a message saying Code language not supported or defined. How do I fix this?

--@block 
CREATE TABLE User(
    id INTEGER PRIMARY KEY,
    email VARCHAR(255) NOT NULL UNIQUE,
    bio TEXT,
    country VARCHAR(2),
);
