MySQL表自动生成SQL语句

以下是MySQL表自动生成SQL语句的详细步骤:

1、创建数据库和数据表

CREATE DATABASE mydatabase;
USE mydatabase;
CREATE TABLE mytable (
    id INT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(50),
    age INT,
    email VARCHAR(100)
);

2、插入数据

INSERT INTO mytable (name, age, email) VALUES ('John Doe', 30, 'johndoe@example.com');
INSERT INTO mytable (name, age, email) VALUES ('Jane Smith', 25, 'janesmith@example.com');
INSERT INTO mytable (name, age, email) VALUES ('Bob Johnson', 35, 'bobjohnson@example.com');

3、查询数据

SELECT * FROM mytable;

4、更新数据

UPDATE mytable SET age = 31 WHERE name = 'John Doe';

5、删除数据

DELETE FROM mytable WHERE name = 'Bob Johnson';

6、创建索引

CREATE INDEX idx_name ON mytable(name);

7、删除索引

DROP INDEX idx_name ON mytable;

8、查看索引信息

SHOW INDEX FROM mytable;
0
