Anda dapat melakukannya dengan sub kueri:
UPDATE Table3 t
SET t.temp = (SELECT s.result+p.resource
FROM table1 s INNER JOIN table2 p
ON(s.email = '[email protected]'))
Jika Tabel3 Anda belum memiliki data:
INSERT INTO Table3
(SELECT s.result+p.resource
FROM table1 s INNER JOIN table2 p
ON(s.email = '[email protected]'))
