golang操作MySQL数据库 方法2

先要下载驱动包，放到$GOPATH/src目录里: https://github.com/Go-SQL-Driver/MySQL

数据库：test 表：user 字段：id,name,view

package main

import (
	"database/sql"
	"fmt"
	_ "github.com/go-sql-driver/mysql"
	"log"
)

var (
	//db         *sql.DB
	dbhostsip  = "127.0.0.1:3306"
	dbusername = "root"
	dbpassowrd = "root"
	dbname     = "test"
)

func mysql_open() *sql.DB {
	Odb, err := sql.Open("mysql", dbusername+":"+dbpassowrd+"@tcp("+dbhostsip+")/"+dbname)

	if err != nil {
		log.Fatalln(err)
		fmt.Println("链接失败")
		return nil
	}
	//defer Odb.Close()
	fmt.Println("链接成功")
	return Odb
}

func mysql_select(db *sql.DB, data string) {
	rows, err := db.Query("select * from user")
	//fmt.Println(db)
	if err != nil {
		log.Fatalln(err)
	}
	//fmt.Println(rows)
	for rows.Next() {
		var id string
		var name string
		var view string
		err = rows.Scan(&id, &name, &view)
		//checkErr(err)
		fmt.Println("content:", id, name, view)
		//fmt.Println(open_send)
		//fmt.Println(cms_send)
		//fmt.Println(time)
	}
}

func main() {
	db := mysql_open()
	err := db.Ping()
	if err != nil {
		log.Fatal(err)
	}

	mysql_select(db, "select * from user")
}
