对于加密 Price 和 PhoneNumber 字段，可以使用 Oracle 数据库中提供的 DBMS_CRYPTO 包进行加密，但是也可以使用其他加密算法，如 AES、RSA 等。

以下是使用 AES 加密算法进行加密的示例代码：

-- 创建密钥
DECLARE
  l_key       RAW(32) := UTL_RAW.cast_to_raw('mysecretkey12345');
  l_iv        RAW(16) := UTL_RAW.cast_to_raw('myinitialvector');
  l_key_handle RAW(2000);
BEGIN
  l_key_handle := DBMS_CRYPTO.create_key(
    algorithm => DBMS_CRYPTO.aes256_cbc,
    key_bytes => 32,
    key => l_key,
    iv => l_iv
  );
END;
/

-- 对 Price 字段进行加密
UPDATE PRODUCT SET Price = DBMS_CRYPTO.encrypt(
  utl_raw.cast_to_raw(Price),
  DBMS_CRYPTO.aes256_cbc,
  l_key_handle,
  l_iv
);

-- 对 PhoneNumber 字段进行加密
UPDATE CUSTOMER SET PhoneNumber = DBMS_CRYPTO.encrypt(
  utl_raw.cast_to_raw(PhoneNumber),
  DBMS_CRYPTO.aes256_cbc,
  l_key_handle,
  l_iv
);

注意：在使用加密算法对数据进行加密时，需要确保密钥的安全性，以免密钥泄露导致数据被解密。
