The example code blocks have some syntax issues.

1. Invalid NULL comparison
2. Premature statement terminator before RETURNING clause

Original

DELETE FROM users
WHERE username = NULL;
RETURNING *;

DELETE FROM users
WHERE username = NULL;
RETURNING id, username, email;

Corrected

DELETE FROM users
WHERE username IS NULL
RETURNING *;

DELETE FROM users
WHERE username IS NULL
RETURNING id, username,email;
