Cmd连接MySQL数据库** 在Cmd命令行中连接MySQL数据库,需要使用以下命令: ``` mysql -u 用户名 -p 密码 -h 主机地址 -P 端口号 ``` 其中,`用户名`和`密码`为MySQL数据库的登录信息,`主机地址`为MySQL数据库所在服务器的IP地址或域名,`端口号`为MySQL数据库的监听端口,默认值为3306。 执行此命令后,将提示输入密码,输入正确密码后即可连接到MySQL数据库。 # 2. Cmd批量操作MySQL数据库 ### 2.1 Cmd命令行操作MySQL数据库 #### 2.1.1 连接MySQL数据库 **命令格式:** ``` mysql -h hostname -u username -p password ``` **参数说明:** * `-h hostname`:指定MySQL服务器主机名或IP地址 * `-u username`:指定连接数据库的用户名 * `-p password`:指定连接数据库的密码 **示例:** ``` mysql -h 127.0.0.1 -u root -p 123456 ``` #### 2.1.2 执行SQL语句 **命令格式:** ``` mysql> SQL语句; ``` **示例:** ``` mysql> CREATE TABLE users (id INT NOT NULL AUTO_INCREMENT, name VARCHAR(255), PRIMARY KEY (id)); ``` #### 2.1.3 获取查询结果 **命令格式:** ``` mysql> SELECT * FROM users; ``` **示例:** ``` mysql> SELECT * FROM users; +----+------+ | id | name | +----+------+ | 1 | John | | 2 | Mary | +----+------+ ``` ### 2.2 Cmd脚本批量操作MySQL数据库 #### 2.2.1 创建Cmd脚本 **代码块:** ``` @echo off mysql -h 127.0.0.1 -u root -p 123456 <<EOF CREATE TABLE users (id INT NOT NULL AUTO_INCREMENT, name VARCHAR(255), PRIMARY KEY (id)); INSERT INTO users (name) VALUES ('John'); INSERT INTO users (name) VALUES ('Mary'); SELECT * FROM users; EOF ``` **逻辑分析:** * `@echo off`:关闭回显,避免命令执行过程中的输出信息显示在控制台中。 * `mysql`:调用MySQL命令行客户端。 * `-h 127.0.0.1 -u root -p 123456`:指定连接MySQL数据库的参数。 * `<<EOF`:开始重定向输入,将后面的SQL语句作为输入发送给MySQL命令行客户端。 * `EOF`:结束重定向输入。 #### 2.2.2 执行Cmd脚本 **命令格式:** ``` cmd /c script.cmd ``` **示例:** ``` cmd /c create_users.cmd ``` # 3. 自动化脚本提升操作效率 ### 3.1 编写自动化脚本 #### 3.1.1 确定脚本功能 编写自动化脚本的第一步是确定脚本的功能。脚本应该完成哪些任务?它应该如何与MySQL数据库交互?明确脚本的目标将有助于指导后续的步骤。 #### 3.1.2 选择合适的编程语言 选择合适的编程语言对于自动化脚本的成功至关重要。对于Cmd脚本,常见的选项包括: - **批处理文件 (BAT)**:一种简单易用的语言,适用于基本任务。 - **PowerShell**:一种更高级的语言,提供更强大的功
