Полнење на табели со информации (пример скрипти)
INSERT INTO users (first_name, last_name, phone_number, email, password, role)
' (i) + 1, |
'Last' (i) + 1,
'123-456-7890',
'user' (i) + 1 '@…',
'password' (i) + 1,
CASE
WHEN i <= 2 THEN 'ADMIN'
ELSE 'USER'
END
FROM generate_series(10003, 12500) AS i;
