Question

INSERT
    INTO
        Payments(Amount)
    VALUES(12.33)
WHERE
    Paymen         


        

Answer 1

It sounds like having the customerID already set. In that case you should use an update statement to update a row. Insert statements will add a completely new row which can not contain a value.
