Oracle中可以使用以下语句导出数据字典:
SELECT table_name, column_name, data_type, data_length, nullable
FROM user_tab_columns
WHERE table_name IN ('CUSTOMER', 'ORDERS', 'PRODUCT', 'ORDER_DETAILS', 'STORE', 'INVENTORY', 'TRANSACTION', 'TRANSACTION_DETAILS', 'EMPLOYEE', 'SALARY', 'SHIFT')
ORDER BY table_name, column_id;
这将查询指定表的列信息,并按表名和列ID排序。可以将查询结果导出为CSV或Excel文件以获取数据字典。

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.

1. 创建Orders订单表的SQL语句:
CREATE TABLE Orders (
OrderID INT PRIMARY KEY,
CustomerID INT,
OrderDate DATE,
TotalAmount DECIMAL(10, 2)
);
2. 向Employees表中插入一条新的员工数据的SQL语句:
INSERT INTO Employees (EmployeeID, FirstName, LastName, Department, Salary)
VALUES (4, 'Linda', 'Wang', 'HR', 4500.00);
3. 查询订单表中订单日期在2023年1月到3月内的订单数量的SQL语句:
SELECT COUNT(*) as OrderCount
FROM Orders
WHERE OrderDate >= '2023-01-01' AND OrderDate <= '2023-03-31';
4. 查询产品表中价格最高的产品名称和价格的SQL语句:
SELECT ProductName, Price
FROM Products
WHERE Price = (SELECT MAX(Price) FROM Products);
5. 查询订单表中订单总金额最高的客户姓名和总金额的SQL语句:
SELECT c.CustomerName, SUM(o.TotalAmount) as TotalAmount
FROM Customers c
INNER JOIN Orders o ON c.CustomerID = o.CustomerID
GROUP BY c.CustomerName
ORDER BY TotalAmount DESC
LIMIT 1;
