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.

oracle怎么create table

在 Oracle 数据库中创建表（Table）是基本的数据库操作之一。以下是创建表的基本语法：

CREATE TABLE table_name (
    column1 datatype constraints,
    column2 datatype constraints,
    ...
    columnN datatype constraints
);

这里是一个示例：

CREATE TABLE Customers (
    CustomerID NUMBER PRIMARY KEY,
    FirstName VARCHAR2(50) NOT NULL,
    LastName VARCHAR2(50),
    Email VARCHAR2(100),
    PhoneNumber VARCHAR2(20),
    RegistrationDate DATE
);

解释一下各个部分：

- `table_name`: 表的名称。
- `column_name`：表中的列名。
- `datatype`：如 `NUMBER`, `VARCHAR2`, `DATE` 等，指定数据类型。
- `constraints`：包括主键（`PRIMARY KEY`）、唯一约束 (`UNIQUE`)、非空约束 (`NOT NULL`)等，帮助定义列的特性和完整性。

创建表之后，可以根据需要使用 `ALTER TABLE` 或 `INSERT INTO` 语句对表结构进行修改或填充数据。
