以下是使用 TDE（Transparent Data Encryption）方法进行加密的示例代码：

-- 创建加密密钥
BEGIN
  DBMS_CRYPTO.ENCRYPT_AES256 (
    KEY => SYS.DBMS_CRYPTO.randombytes(32),
    KEY_STORE => 'MY_KEYSTORE',
    KEY_ID => 123,
    USE_CASE => DBMS_CRYPTO.ENCRYPT
  );
END;
/

-- 开启 TDE 加密
ALTER TABLE CUSTOMER MODIFY (PhoneNumber ENCRYPT);

-- 对 Price 字段进行加密
ALTER TABLE PRODUCT MODIFY (Price ENCRYPT);

-- 对 PhoneNumber 字段进行加密
ALTER TABLE CUSTOMER MODIFY (PhoneNumber ENCRYPT);

注意：在使用 TDE 进行加密时，需要先创建加密密钥并将其存储在 Oracle 数据库的密钥库中，然后对需要加密的字段进行加密。加密后的数据可以直接存储在数据库中，并在查询时自动解密。

CREATE DATABASE retail_store;CREATE TABLE CUSTOMER ( CustomerID NUMBER PRIMARY KEY, Name VARCHAR2(100), Address VARCHAR2(200), PhoneNumber VARCHAR2(20), Email VARCHAR2(100), LoyaltyStatus VARCHAR2(20));CREATE TABLE ORDERS ( OrderID NUMBER PRIMARY KEY, OrderDate DATE, OrderStatus VARCHAR2(20), TotalCost NUMBER, CustomerID NUMBER, CONSTRAINT FK_ORDER_CUSTOMER FOREIGN KEY (CustomerID) REFERENCES CUSTOMER(CustomerID));代码有错吗

以上 SQL 代码没有语法错误。它创建了一个名为 `retail_store` 的数据库，其中包含两个表：`CUSTOMER` 和 `ORDERS`。`CUSTOMER` 表包含 `CustomerID`、`Name`、`Address`、`PhoneNumber`、`Email` 和 `LoyaltyStatus` 这几个列，其中 `CustomerID` 是主键。`ORDERS` 表包含 `OrderID`、`OrderDate`、`OrderStatus`、`TotalCost` 和 `CustomerID` 这几个列，其中 `OrderID` 是主键，`CustomerID` 列是外键，引用了 `CUSTOMER` 表的 `CustomerID` 主键列。

Update the second customer’s email address with this new email address: you@dzi.com， CREATE TABLE CUSTOMER ( CustomerID NUMBER(10) PRIMARY KEY, FirstName VARCHAR2(50), LastName VARCHAR2(50), Email VARCHAR2(100), PhoneNumber VARCHAR2(20) );

To update the second customer's email address with the new email address "you@dzi.com", you can use the following SQL query:

UPDATE CUSTOMER
SET Email = 'you@dzi.com'
WHERE CustomerID = 2;

This assumes that the second customer has a CustomerID of 2 in the CUSTOMER table. If the ID is different, you will need to adjust the query accordingly.

Also, this assumes that the table already exists. If not, you can use the following SQL query to create the CUSTOMER table with the specified columns:

CREATE TABLE CUSTOMER (
  CustomerID NUMBER(10) PRIMARY KEY,
  FirstName VARCHAR2(50),
  LastName VARCHAR2(50),
  Email VARCHAR2(100),
  PhoneNumber VARCHAR2(20)
);

This creates a table named CUSTOMER with columns for CustomerID, FirstName, LastName, Email, and PhoneNumber. The CustomerID column is specified as the primary key.
