用mysql创建动物园管理系统 要具体代码

好的，首先你需要在MySQL中创建一个名为"zoo"的数据库，然后创建以下4个表格：

1. animals表格，用于存储动物的信息

CREATE TABLE animals (
    id INT(11) NOT NULL AUTO_INCREMENT,
    name VARCHAR(50) NOT NULL,
    species VARCHAR(50) NOT NULL,
    age INT(11) NOT NULL,
    gender ENUM('male','female') NOT NULL,
    exhibit_id INT(11) NOT NULL,
    PRIMARY KEY (id),
    FOREIGN KEY (exhibit_id) REFERENCES exhibits(id)
);

2. exhibits表格，用于存储展览的信息

CREATE TABLE exhibits (
    id INT(11) NOT NULL AUTO_INCREMENT,
    name VARCHAR(50) NOT NULL,
    location VARCHAR(50) NOT NULL,
    PRIMARY KEY (id)
);

3. employees表格，用于存储员工的信息

CREATE TABLE employees (
    id INT(11) NOT NULL AUTO_INCREMENT,
    name VARCHAR(50) NOT NULL,
    job_title VARCHAR(50) NOT NULL,
    exhibit_id INT(11) NOT NULL,
    PRIMARY KEY (id),
    FOREIGN KEY (exhibit_id) REFERENCES exhibits(id)
);

4. visitors表格，用于存储游客的信息

CREATE TABLE visitors (
    id INT(11) NOT NULL AUTO_INCREMENT,
    name VARCHAR(50) NOT NULL,
    age INT(11) NOT NULL,
    gender ENUM('male','female') NOT NULL,
    PRIMARY KEY (id)
);

以上是创建表格的代码，你可以根据需求自己修改表格的字段和类型。接下来，你可以插入一些数据来测试：

INSERT INTO exhibits(name, location) VALUES('Big Cats', 'South Africa');
INSERT INTO exhibits(name, location) VALUES('Aquatic', 'North America');
INSERT INTO employees(name, job_title, exhibit_id) VALUES('John', 'Zookeeper', 1);
INSERT INTO employees(name, job_title, exhibit_id) VALUES('Jane', 'Aquarist', 2);
INSERT INTO animals(name, species, age, gender, exhibit_id) VALUES('Tiger', 'Panthera tigris', 6, 'male', 1);
INSERT INTO animals(name, species, age, gender, exhibit_id) VALUES('Dolphin', 'Tursiops truncatus', 10, 'female', 2);
INSERT INTO visitors(name, age, gender) VALUES('Tom', 25, 'male');
INSERT INTO visitors(name, age, gender) VALUES('Mary', 30, 'female');

这些数据可以帮助你测试查询和过滤操作。希望这些代码能对你有所帮助！
