如何利用MySQL和C++开发一个基于命令行的图书管理系统

CREATE TABLE books (
    book_id INT PRIMARY KEY,
    title VARCHAR(100),
    author VARCHAR(100),
    publication_date DATE
);

CREATE TABLE users (
    user_id INT PRIMARY KEY,
    username VARCHAR(100),
    passWord VARCHAR(100)
);

CREATE TABLE borrowings (
    borrowing_id INT PRIMARY KEY,
    book_id INT,
    user_id INT,
    borrowing_date DATE,
    return_date DATE,
    FOREIGN KEY (book_id) REFERENCES books(book_id),
    FOREIGN KEY (user_id) REFERENCES users(user_id)
);

#include <iOStream>
#include <mysql.h>

MYSQL* connect() {
    MYSQL* conn;
    conn = mysql_init(NULL);
    if (conn == NULL) {
        std::cout << "Failed to initialize mysql client library" << std::endl;
        exit(1);
    }
    if (mysql_real_connect(conn, "localhost", "username", "password", "database_name", 0, NULL, 0) == NULL) {
        std::cout << "Failed to connect to database" << std::endl;
        exit(1);
    }
    return conn;
}

void addBook(MYSQL* conn, int book_id, std::string title, std::string author, std::string publication_date) {
    std::string query = "INSERT INTO books (book_id, title, author, publication_date) VALUES ("
                      + std::to_string(book_id) + ",'" + title + "','" + author + "','" + publication_date + "')";
    if (mysql_query(conn, query.c_str()) != 0) {
        std::cout << mysql_error(conn) << std::endl;
    }
}

int main() {
    MYSQL* conn = connect();
    addBook(conn, 1, "C++ Primer", "Stanley B. Lippman", "1998-10-01");
    // ... 其他功能函数的调用

    mysql_close(conn);
    return 0;
}
