Unknown column ‘section’ in ‘where clause’ SQL

So I was trying to create a library query as my project in SQL (MySql Workbench) and I have this code below

CREATE TABLE library (
    book VARCHAR(100),
    author VARCHAR(200),
    section INT,
    PRIMARY KEY(section)
);

INSERT INTO library VALUES('The Owl','Mr ochwitch',3);
INSERT INTO library VALUES('Austrian','Wolfgang',7);
SELECT * FROM library WHERE section = 3;

SELECT * FROM library;

where I’m trying to select a book on section ‘3’ and expected

book      author     section
'Austrian' 'Woflgang' 3

as my output but I got

16:03:47    SELECT * FROM library WHERE section = 3 LIMIT 0, 1000   Error Code: 1054. Unknown column 'section' in 'where clause'    0.000 sec

error instead. Please help
