我有一个简单的更新过程。因此，我希望仅更新它们不是空值的字段。我该怎么做？

  PROCEDURE UpdateCustomerInfo(
      CustomerID                 IN NUMBER,
      CustomerType                 IN VARCHAR2,
      CustomerName        IN VARCHAR2,
      CustomerGender          IN VARCHAR2,
      CustomerBirthday        IN DATE)
  AS
  BEGIN
    UPDATE CUSTOMER_INFO
    SET CUSTOMER_TYPE =CustomerType,
     CUSTOMER_NAME =CustomerName,
     CUSTOMER_GENDER =CustomerGender,
     CUSTOMER_BIRTHDAY =CustomerBirthday
    WHERE CUSTOMER_ID = CustomerID;
    COMMIT;

  END CUSTOMER_INFO

有人可以帮助我吗？

谢谢
