go连接mysql数据库

首先，在mysql数据库中建立一张表:

CREATE TABLE `t_test` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `age` int(11) DEFAULT '0',
  `name` varchar(32) COLLATE utf8_bin DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin;

// 需要先安装: go get github.com/go-sql-driver/mysql

package main

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

func main() {
	db, err := sql.Open("mysql", "root:123@tcp(192.168.10.15:3306)/gamedata_tian?charset=utf8")
	if err != nil {
		fmt.Println(err)
		return
	}

	defer db.Close()

	var result sql.Result
	result, err = db.Exec("insert into t_test(age, name) values(?,?)", 13, "joe")
	if err != nil {
		fmt.Println(err)
		return
	}

	lastId, _ := result.LastInsertId()
	fmt.Println("新插入记录的ID为", lastId)

	var row *sql.Row
	row = db.QueryRow("select * from t_test")
	var name string
	var id, age int
	err = row.Scan(&id, &age, &name)
	if err != nil {
		fmt.Println(err)
		return
	}

	fmt.Println(id, "\t", name, "\t", age)

	result, err = db.Exec("insert into t_test(age, name) values(?,?)", 24, "black")

	var rows *sql.Rows
	rows, err = db.Query("select * from t_test")
	if err != nil {
		fmt.Println(err)
		return
	}

	for rows.Next() {
		var name string
		var id, age int
		rows.Scan(&id, &age, &name)
		fmt.Println(id, "\t", name, "\t", age)
	}
	rows.Close()

	db.Exec("truncate table t_test")
}
