The Go language USES the methods of MySql

This article illustrates the use of MySql in the Go language. Share with you for your reference. The details are as follows:

This code requires that mysql's go language driver be installed first.

First install mysql's go language driver:

go get github.com/ziutek/mymysql/godrv

The sample code is as follows:

package users

import (

    "database/sql"

    "fmt"

    _ "github.com/ziutek/mymysql/godrv"

)

  

const (

    DB_NAME = "mysql_database_name"

    DB_USER = "mysql_user"

    DB_PASS = "mysql_password"

)

  

type User struct {

    Id      int    `json:"id"`

    Name string `json:"name"`

    Alias   string `json:"alias"`

}

  

func OpenDB() *sql.DB {

    db, err := sql.Open("mymysql", fmt.Sprintf("%s/%s/%s", DB_NAME, DB_USER, DB_PASS))

    if err != nil {

        panic(err)

    }

    return db

}

  

func UserById(id int) User {

    db := OpenDB()

    defer db.Close()

    row := db.QueryRow("SELECT `id`, `name`,`alias` FROM `users` WHERE id=?", id)

    user := new(User)

    row.Scan(&user.Id, &user.Name, &user.Alias)

    return user

}

I hope this article has been helpful to your programming of Go language.
