CS50: LIKE operator, variable substitution with % expansion

by

Pass the entire search string as the parameter to the LIKE operator:

results = db.execute(text("SELECT * FROM books WHERE title LIKE :search"),
                     {"search": f"%{search}%"}).fetchall();

or alternatively concatenate in the database:

results = db.execute(
    text("SELECT * FROM books WHERE title LIKE ('%' || :search || '%')"),
    {"search": search}).fetchall();
