go使用MYSQL数据库进行操作

package main

import (

"fmt"

)

func main() {

db, err := sql.Open("mysql", "root:root@/test?charset=utf8")

checkErr(err)

//插入数据

stmt, err := db.Prepare("INSERT userinfo SET username=?,departname=?,created=?")

checkErr(err)

res, err := stmt.Exec("astaxie", "研发部门", "2012-12-09")

checkErr(err)

id, err := res.LastInsertId()

checkErr(err)

fmt.Println(id)

//更新数据

stmt, err = db.Prepare("update userinfo set username=? where uid=?")

checkErr(err)

res, err = stmt.Exec("astaxieupdate", id)

checkErr(err)

affect, err := res.RowsAffected()

checkErr(err)

fmt.Println(affect)

//查询数据

rows, err := db.Query("SELECT * FROM userinfo")

//删除数据
