Views

A view saves a query under a name.

Task

What is a view?

The editor already contains a starting point. Change it until every check passes — the Next task button unlocks when it does.

What you start with
CREATE VIEW unpaid AS SELECT students.name, fees.amount FROM fees JOIN students ON students.id = fees.student_id WHERE fees.paid = 0;
SELECT name FROM unpaid;
Syntax reference
CREATE VIEW unpaid AS SELECT students.name, fees.amount FROM fees JOIN students ON students.id = fees.student_id WHERE fees.paid = 0;
SELECT name FROM unpaid;

Read it, then write it yourself. Copy-paste teaches nothing.

The sample database
CREATE TABLE courses (id INTEGER PRIMARY KEY, title TEXT, monthly_fee INTEGER);
CREATE TABLE students (id INTEGER PRIMARY KEY, name TEXT, city TEXT, course_id INTEGER, joined TEXT);
CREATE TABLE fees (id INTEGER PRIMARY KEY, student_id INTEGER, month TEXT, amount INTEGER, paid INTEGER);

INSERT INTO courses VALUES (1,'Web Design',9000),(2,'Python',11667),(3,'JavaScript',11667),(4,'AI & Prompt Engineering',15000);
INSERT INTO students VALUES
