The ConsultationFee field in a database table named Appointment stores the cost of a patient's medical consultation in pounds (£).

A clinic administrator wants to write a query to increase the ConsultationFee by 12 for all appointments that have a DurationMinutes of greater than 45.

The drafted query is shown in Figure 1.

Figure 1

UPDATE Appointment
SET ConsultationFee = ConsultationFee + 8
WHERE DurationMinutes <= 45

The query contains two errors. Refine the query in Figure 1 to correct the errors.
