SQL库数据库模式

我的问题是找到约翰·史密斯目前正在借出的所有书籍的书号、书名和截止日期

这是模式：

• 图书（书号（PK）、ISBN、书名、作者、出版年份、类别）
• 成员（成员ID（PK）、姓、名、地址、电话号码、限制）
• 当前贷款（memberID（PK）、bookID（PK）、贷款日期、到期日）
• 历史记录（memberID（主键）、bookID（主键）、贷款日期（主键）、归还日期）

会员可以从图书馆借书。他们可以借阅的图书数量受成员关系的“限制”字段限制（不同成员的限制可能不同）。书的类别包括小说、非小说、儿童读物和参考读物。CurrentLoan表表示有关当前已签出的书籍的信息。当书籍返回到库中时，该记录将从CurrentLoad关系中删除，并将插入到历史关系中，与归还日期保持一致。一个图书馆可能有同一本书的多个副本，在这种情况下，每个副本都有自己的图书ID，但所有副本共享相同的ISBN

这是查询，但它输出所有当前贷款值。有人能帮我让它只输出John Smith提供的值吗：

SELECT 
    Book.bookID, title, due_date 
FROM 
    Book, Member_ 
INNER JOIN 
    CurrentLoan ON Book.bookID = CurrentLoan.bookID 
WHERE 
    Member_.lastname = 'Smith' AND Member_.firstname = 'John';

我需要回答的问题是：查找John Smith当前正在借出的所有书籍的图书ID、标题和截止日期。

试试：

SELECT book.bookID, title, due_date 
FROM Book 
INNER JOIN CurrentLoan ON Book.bookID= CurrentLoan.bookID 
inner join Member on Member.memberID = CurrentLoan.memberID
WHERE Member.lastname='Smith' AND Member.firstname= 'John';

---

我还有一个问题，请查找过去或现在从未借过任何书籍的会员ID、姓氏和名字。你能帮我选择member.*从member left在CurrentLoan上加入CurrentLoan.memberID=member.memberID在history上左加入history.memberID=member.memberID其中history.memberID为null，CurrentLoan.memberID为null我想这是来自该成员的。*将所有成员替换为mamber_-旧样式的逗号分隔列表在ANSI-92 SQL标准中（25年前），表格样式被正确的ANSI

JOIN

语法所取代，不鼓励使用

SELECT book.bookID, title, due_date 
FROM Book 
INNER JOIN CurrentLoan ON Book.bookID= CurrentLoan.bookID 
inner join Member on Member.memberID = CurrentLoan.memberID
WHERE Member.lastname='Smith' AND Member.firstname= 'John';
