CREATE TABLE PRODUCT ( ProductID NUMBER(10) PRIMARY KEY, ProductName VARCHAR2(100), Description VARCHAR2(500), Price NUMBER(10,2), Category VARCHAR2(50) ); 以group25 为密钥加密Price列

由于我无法直接访问您的数据库，我可以提供一些伪代码示例来说明如何向每个表中插入随机数据。 INSERT INTO CUSTOMER (CustomerID, Name, Address, PhoneNumber, Email, LoyaltyStatus) VALUES (1, 'John Doe', '123 Main St', '555-555-5555', '[email protected]', 'Gold'); -- Repeat this statement with different values to insert 10 rows into this table INSERT INTO ORDERS (OrderID, OrderDate, OrderStatus, TotalCost, CustomerID) VALUES (1, TO_DATE('2022/01/01', 'yyyy/mm/dd'), 'Pending', 50.00, 1); -- Repeat this statement with different values to insert 10 rows into this table INSERT INTO ORDER_DETAILS (OrderDetailID, OrderID, ProductID, ProductName, Price, Quantity, Subtotal) VALUES (1, 1, 1, 'Product 1', 10.00, 2, 20.00); -- Repeat this statement with different values to insert 10 rows into this table INSERT INTO PRODUCT (ProductID, ProductName, Description, Price, Category) VALUES (1, 'Product 1', 'Description for Product 1', 10.00, 'Category 1'); -- Repeat this statement with different values to insert 10 rows into this table INSERT INTO STORE (StoreID, StoreName, Location, HoursOfOperation) VALUES (1, 'Store 1', '123 Main St', '8am-6pm'); -- Repeat this statement with different values to insert 10 rows into this table INSERT INTO INVENTORY (ProductID, StoreID, QuantityOnHand, ReorderPoint) VALUES (1, 1, 100, 20); -- Repeat this statement with different values to insert 10 rows into this table INSERT INTO "TRANSACTION" (TransactionID, TransactionDate, TransactionType, TotalAmount, CustomerID) VALUES (1, TO_DATE('2022/01/01', 'yyyy/mm/dd'), 'Sale', 50.00, 1); -- Repeat this statement with different values to insert 10 rows into this table INSERT INTO TRANSACTION_DETAILS (TransactionDetailID, TransactionID, ProductID, ProductName, Price, Quantity, Subtotal) VALUES (1, 1, 1, 'Product 1', 10.00, 2, 20.00); -- Repeat this statement with different values to insert 10 rows into this table INSERT INTO EMPLOYEE (EmployeeID, Name, Address, PhoneNumber, Email, Position) VALUES (1, 'Jane Smith', '456 Oak St', '555-555-5555', '[email protected]', 'Manager'); -- Repeat this statement with different values to insert 10 rows into this table INSERT INTO SALARY (EmployeeID, StartDate, SalaryAmount, EndDate) VALUES (1, TO_DATE('2022/01/01', 'yyyy/mm/dd'), 50000.00, TO_DATE('2023/01/01', 'yyyy/mm/dd')); -- Repeat this statement with different values to insert 10 rows into this table INSERT INTO SHIFT (ShiftID, StartTime, EndTime, StoreID, EmployeeID) VALUES (1, TO_TIMESTAMP('2022/01/01 08:00:00', 'yyyy/mm/dd hh24:mi:ss'), TO_TIMESTAMP('2022/01/01 16:00:00', 'yyyy/mm/dd hh24:mi:ss'), 1, 1); -- Repeat this statement with different values to insert 10 rows into this table

可以使用 Oracle 提供的 DBMS_CRYPTO 包来加密 Price 和 PhoneNumber 字段。首先需要创建一个加密密钥，然后使用该密钥对数据进行加密和解密。 以下是加密 Price 和 PhoneNumber 字段的示例 SQL 代码： -- 创建密钥 DECLARE key_raw RAW(32) := utl_raw.cast_to_raw('my_secret_key'); encryption_type PLS_INTEGER := dbms_crypto.ENCRYPT_AES256 + dbms_crypto.CHAIN_CBC + dbms_crypto.PAD_PKCS5; key_handle NUMBER; BEGIN key_handle := dbms_crypto.create_key( key_length => 32, key_type => dbms_crypto.TYPE_AES256, key_source => key_raw ); END; / -- 加密 Price 字段 UPDATE PRODUCT SET Price = dbms_crypto.encrypt( src => to_char(Price), typ => encryption_type, key => key_handle ); -- 加密 PhoneNumber 字段 UPDATE CUSTOMER SET PhoneNumber = dbms_crypto.encrypt( src => PhoneNumber, typ => encryption_type, key => key_handle ); 注意，在实际应用中，需要妥善保管密钥，确保数据的安全性。
