写出sql语句,客户能够在网上浏览我们的书目,然后下订单。现在我们是通过电话接受订单。我们的客户主要是公司客户,他们打电话给我们,并给出书的ISBN号码和数量。然后我们就准备发货。如果我们没有足够的库存,就需要再订购拷贝,并且将发货的时间推迟到新的拷贝到来,并希望将一个顾客的所定的书一起装运。我们的目录包括我们卖的所有书。对于每本书,目录包括它的ISBN号码、题目、作者、购买价格、销售价格和书的出版年份。我们的顾客大多都是回头客,而且我们都有他们的记录,包括姓名、地址和信用卡号。新的客户在使用我们的网页之前必须打电话给我们以便建立一个帐号。在我们的新Web站点上,顾客首先应该用他们唯一的顾客标识号来登录我们的网站。然后他们就能浏览我们的书目,并且在线下订单。

好的,下面是可能的SQL语句,用于实现客户在线浏览书目并下订单的功能:
1. 查询所有书籍信息:
```sql
SELECT BookID, Title, Author, Publisher, PublishDate, ISBN, UnitPrice, Quantity, CategoryName
FROM Books
JOIN Categories ON Books.CategoryID = Categories.CategoryID;
```
2. 查询某本书籍的信息:
```sql
SELECT BookID, Title, Author, Publisher, PublishDate, ISBN, UnitPrice, Quantity, CategoryName
FROM Books
JOIN Categories ON Books.CategoryID = Categories.CategoryID
WHERE ISBN = 'xxxxx';
```
3. 插入新订单:
```sql
INSERT INTO Orders (CustomerID, OrderDate, TotalAmount)
VALUES (xxx, 'yyyy-mm-dd hh:mm:ss', zzzz);
```
4. 插入新订单明细:
```sql
INSERT INTO OrderDetails (OrderID, BookID, UnitPrice, Quantity)
VALUES (xxx, yyy, zzz, www);
```
5. 查询某个客户的订单历史:
```sql
SELECT Orders.OrderID, OrderDate, TotalAmount, Title, Quantity, (UnitPrice * Quantity) AS Subtotal
FROM Orders
JOIN OrderDetails ON Orders.OrderID = OrderDetails.OrderID
JOIN Books ON OrderDetails.BookID = Books.BookID
WHERE CustomerID = xxx;
```
6. 查询库存不足的书籍:
```sql
SELECT BookID, Title, Quantity
FROM Books
WHERE Quantity < xxx;
```
7. 订购新拷贝:
```sql
UPDATE Books SET Quantity = Quantity + xxx WHERE BookID = yyy;
```
8. 查询某本书籍的出版年份:
```sql
SELECT YEAR(PublishDate) AS PublishYear
FROM Books
WHERE ISBN = 'xxxxx';
```
9. 查询某个客户的个人信息:
```sql
SELECT UserName, Address, CreditCardNumber
FROM Customers
WHERE CustomerID = xxx;
```
10. 插入新客户:
```sql
INSERT INTO Customers (UserName, Password, Email, Phone, Address, CreditCardNumber)
VALUES ('xxxxx', 'yyyyy', 'zzzzz', 'wwwww', 'uuuuu', 'vvvvv');
```
以上只是一些基本的SQL语句,实际应用中还需要根据具体需求进行调整和优化。
