操作mysql用到的庫是sqlx

需要先安裝sqlx和mysql,sqlx是在mysql驅(qū)動(dòng)之上封裝的包

go get "github.com/go-sql-driver/mysql"

go get "github.com/jmoiron/sqlx"

創(chuàng)建測(cè)試表

CREATE TABLE person (

user_id int primary key auto_increment,

username varchar(260),

sex varchar(260),

email varchar(260)

);

CREATE TABLE place (

country varchar(200),

city varchar(200),

telcode int

);

初始化數(shù)據(jù)庫連接

package main

import (

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

"github.com/jmoiron/sqlx"

)

var Db *sqlx.DB

func init() {

database, err := sqlx.Open("mysql", "root:root@tcp(127.0.0.1:3306)/test")

if err != nil {

fmt.Println("open mysql failed,", err)

return

}

Db = database

}

Insert

package main

import (

"fmt"

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

"github.com/jmoiron/sqlx"

)

type Person struct {

UserId int `db:"user_id"`

Username string `db:"username"`

Sex string `db:"sex"`

Email string `db:"email"`

}

type Place struct {

Country string `db:"country"`

City string `db:"city"`

TelCode int `db:"telcode"`

}

var Db *sqlx.DB

func init() {

database, err := sqlx.Open("mysql", "root:root@tcp(127.0.0.1:3306)/test")

if err != nil {

fmt.Println("open mysql failed,", err)

return

}

Db = database

}

func main() {

r, err := Db.Exec("insert into person(username, sex, email)values(?, ?, ?)", "stu001", "man", "stu01@qq.com")

if err != nil {

fmt.Println("exec failed, ", err)

return

}

id, err := r.LastInsertId()

if err != nil {

fmt.Println("exec failed, ", err)

return

}

fmt.Println("insert succ:", id)

}

Select

package main

import (

"fmt"

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

"github.com/jmoiron/sqlx"

)

type Person struct {

UserId int `db:"user_id"`

Username string `db:"username"`

Sex string `db:"sex"`

Email string `db:"email"`

}

type Place struct {

Country string `db:"country"`

City string `db:"city"`

TelCode int `db:"telcode"`

}

var Db *sqlx.DB

func init() {

database, err := sqlx.Open("mysql", "root:root@tcp(127.0.0.1:3306)/test")

if err != nil {

fmt.Println("open mysql failed,", err)

return

}

Db = database

}

func main() {

var person []Person

err := Db.Select(&person, "select user_id, username, sex, email from person where user_id=?", 1)

if err != nil {

fmt.Println("exec failed, ", err)

return

}

fmt.Println("select succ:", person)

}

Update

package main

import (

"fmt"

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

"github.com/jmoiron/sqlx"

)

type Person struct {

UserId int `db:"user_id"`

Username string `db:"username"`

Sex string `db:"sex"`

Email string `db:"email"`

}

type Place struct {

Country string `db:"country"`

City string `db:"city"`

TelCode int `db:"telcode"`

}

var Db *sqlx.DB

func init() {

database, err := sqlx.Open("mysql", "root:root@tcp(127.0.0.1:3306)/test")

if err != nil {

fmt.Println("open mysql failed,", err)

return

}

Db = database

}

func main() {

_, err := Db.Exec("update person set username=? where user_id=?", "stu0003", 1)

if err != nil {

fmt.Println("exec failed, ", err)

return

}

}

Delete

package main

import (

"fmt"

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

"github.com/jmoiron/sqlx"

)

type Person struct {

UserId int `db:"user_id"`

Username string `db:"username"`

Sex string `db:"sex"`

Email string `db:"email"`

}

type Place struct {

Country string `db:"country"`

City string `db:"city"`

TelCode int `db:"telcode"`

}

var Db *sqlx.DB

func init() {

database, err := sqlx.Open("mysql", "root:root@tcp(127.0.0.1:3306)/test")

if err != nil {

fmt.Println("open mysql failed,", err)

return

}

Db = database

}

func main() {

_, err := Db.Exec("delete from person where user_id=?", 1)

if err != nil {

fmt.Println("exec failed, ", err)

return

}

fmt.Println("delete succ")

}
