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;
