Полнење на табели со информации (пример скрипти)


INSERT INTO users (first_name, last_name, phone_number, email, password, role)

SELECT 'First' '
' (i) + 1,
'Last'
(i) + 1,

'123-456-7890',

'user' 'password'
(i) + 1 '@…',
(i) + 1,

CASE

WHEN i <= 2 THEN 'ADMIN'
ELSE 'USER'
END

FROM generate_series(10003, 12500) AS i;
