To insert updates:
$result = odbc_exec($cnx, "INSERT INTO Customers(Email) VALUES ('sales@grandhotels.com')"); $affected = odbc_num_rows($result);
UPDATE
To retrieve updates:
$result = odbc_exec($cnx, "UPDATE Customers SET Email = 'sales@grandhotels.com' WHERE Delinquent = 'False'"); $affected = odbc_num_rows($result);
DELETE
To delete updates:
$result = odbc_exec($cnx, "DELETE FROM Customers WHERE Id = '123456'"); $affected = odbc_num_rows($result);
