Di SQL Server Anda dapat melakukan sesuatu seperti:
UPDATE Table_1 SET Column_2 = t2.Column_2 FROM Table_1 AS t1 INNER JOIN Table_2 AS t2 ON t2.Column_1 = t1.Column_1
atau semacamnya
UPDATE Table_1 SET Column_2 = ( SELECT t2.Column_2 FROM Table_2 AS t2 WHERE t2.Column_1 = Table_1.Column_1 )
Tentu saja jika Anda memiliki beberapa baris di Tabel_2, Anda akan mendapatkan kesalahan....
