不想多说话，先把golang和mysql连接好，环境配置好，然后直接上代码就行了，代码可直接运行。

package main

import (
	"database/sql"
	"fmt"

	_ "github.com/go-sql-driver/mysql"
)

func main() {
	// MySQL 连接字符串
	dbConnectionString := "root:nmnmnm67890890@tcp(localhost:3306)/test1"

	// 打开数据库连接
	db, err := sql.Open("mysql", dbConnectionString)
	if err != nil {
		panic(err.Error())
	}
	defer db.Close()

	// 尝试连接数据库
	err = db.Ping()
	if err != nil {
		panic(err.Error())
	}

	fmt.Println("Successfully connected to the database!")

	// 创建表
	_, err = db.Exec(`
		CREATE TABLE IF NOT EXISTS users (
			id INT NOT NULL AUTO_INCREMENT,
			name VARCHAR(50) NOT NULL,
			age INT NOT NULL,
			PRIMARY KEY (id)
		)
	`)
	if err != nil {
		panic(err.Error())
	}

	fmt.Println("Table 'users' created successfully!")

	// 插入一条数据
	_, err = db.Exec("INSERT INTO users (name, age) VALUES (?, ?)", "John Doe", 30)
	if err != nil {
		panic(err.Error())
	}

	fmt.Println("Data inserted successfully!")

	// 查询数据
	rows, err := db.Query("SELECT * FROM users")
	if err != nil {
		panic(err.Error())
	}
	defer rows.Close()

	// 遍历查询结果
	for rows.Next() {
		var id int
		var name string
		var age int

		err := rows.Scan(&id, &name, &age)
		if err != nil {
			panic(err.Error())
		}

		fmt.Printf("ID: %d, Name: %s, Age: %d\n", id, name, age)
	}

	// 检查可能的错误
	if err := rows.Err(); err != nil {
		panic(err.Error())
	}
}

看运行结果
