Go语言从入门到精通九——使用golang操作mysql和redis
package main
import (
"fmt"
"github.com/jmoiron/sqlx"
_ "github.com/go-sql-driver/mysql" //初始化一个mysql驱动，必须
)
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() {
//"mysql"指定数据库类型， /test指定数据库 root:123 冒号隔开密码 root账号 123密码
database, err := sqlx.Open("mysql", "root:930808@tcp(127.0.0.1:3306)/go_test")
if err != nil {
fmt.Println("open mysql failed,", err)
return
}
fmt.Println("连接数据库成功！")
Db = database
}
func main() {
//插入数据入表
r, err := Db.Exec("insert into person(username,sex,email)values(?,?,?)", "dave", "man", "dave@outlook.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)
}
