sql server创建图书馆管理系统的代码

SQL Server 创建图书馆管理系统的代码需要涉及多个表和关联关系。以下是一个简化的实现示例：

-- 创建图书馆表
CREATE TABLE Library (
LibraryID INT PRIMARY KEY,
LibraryName VARCHAR(100) NOT NULL
);

-- 创建图书表
CREATE TABLE Book (
BookID INT PRIMARY KEY,
LibraryID INT,
BookName VARCHAR(100) NOT NULL,
Author VARCHAR(100) NOT NULL,
CONSTRAINT FK_Book_Library FOREIGN KEY (LibraryID) REFERENCES Library(LibraryID)
);

-- 创建读者表
CREATE TABLE Reader (
ReaderID INT PRIMARY KEY,
ReaderName VARCHAR(100) NOT NULL
);

-- 创建借阅记录表
CREATE TABLE Borrow (
BorrowID INT PRIMARY KEY,
ReaderID INT,
BookID INT,
BorrowDate DATE NOT NULL,
ReturnDate DATE NOT NULL,
CONSTRAINT FK_Borrow_Reader FOREIGN KEY (ReaderID) REFERENCES Reader(ReaderID),
CONSTRAINT FK_Borrow_Book FOREIGN KEY (BookID) REFERENCES Book(BookID)
);

-- 创建查询图书馆书籍的存储过程
CREATE PROCEDURE GetLibraryBooks
@LibraryID INT
AS
BEGIN
SELECT Library.LibraryName, Book.BookName, Book.Author
FROM Library
INNER JOIN Book ON Library.LibraryID = Book.LibraryID
WHERE Library.LibraryID = @LibraryID;
END;

-- 创建查询读者借阅记录的存储过程
CREATE PROCEDURE GetReaderBorrows
@ReaderID INT
AS
BEGIN
SELECT Reader.ReaderName, Book.BookName, Borrow.BorrowDate, Borrow.ReturnDate
FROM Reader
INNER JOIN Borrow ON Reader.ReaderID = Borrow.ReaderID
INNER JOIN Book ON Borrow.BookID = Book.BookID
WHERE Reader.ReaderID = @ReaderID;
END;

这只是一个简单的示例，实际情况中可能还需要更多的表和功能，例如管理员表、预约表等等。这些代码可以作为图书馆管理系统数据库的基础，通过增加更多的表和存储过程来满足实际需求。
