mysql中date/datetime类型自动转go的时间类型time.Time

在DSN中需要加入parseTime=true&&loc=Local，或
charset=utf8mb4&loc=Asia%2FShanghai&parseTime=true。

package main_test

import (
	"database/sql"
	"fmt"
	"testing"
	"time"

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

func TestMysqlDatetime(t *testing.T) {

	type Student struct {
		CreateAt time.Time
	}

	db, _ := sql.Open("mysql", "user:password@tcp(127.0.0.1:3306)/test?parseTime=true&&loc=Local")
	rows, _ := db.Query("SELECT create_at FROM `student`")
	defer rows.Close()
	var student Student
	for rows.Next() {
		err := rows.Scan(&student.CreateAt)
		if err != nil {
			fmt.Printf("scan failed, err:%v\n", err)
			return
		}
		fmt.Println("student.CreateAt:", student.CreateAt.Format("2006-01-02 15:04:05"))
	}
}
