SELECT T1.zip_postcode FROM Addresses AS T1 JOIN Staff AS T2 ON T1.address_id = T2.staff_address_id WHERE T2.first_name = "Janessa" AND T2.last_name = "Sawayn"
Berapa kode pos staf dengan nama depan sebagai Janessa dan nama belakang saat sawayn hidup?
CREATE TABLE Addresses (zip_postcode VARCHAR, address_id VARCHAR); CREATE TABLE Staff (staff_address_id VARCHAR, first_name VARCHAR, last_name VARCHAR)
