Mysql事务
1)原子性
2)一致性
3)隔离性
4)持久性
示例代码
package main
import (
"fmt"
_ "github.com/go-sql-driver/mysql" //初始化一个mysql驱动,必须
"github.com/jmoiron/sqlx"
)
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指定打开的数据库 root:123 冒号隔开密码 root账号 123密码
database, err := sqlx.Open("mysql", "root@tcp(127.0.0.1:3306)/test")
if err != nil {
fmt.Println("open mysql failed,", err)
return
}
Db = database
}
func main() {
//事务操作
conn, err := Db.Begin()
if err != nil {
return
}
//插入数据入表
r, err := Db.Exec("insert into person(username,sex,email)values(?,?,?)", "chaoge", "man", "yc_uuu@163.com")
if err != nil {
fmt.Println("exec failed,", err)
return
}
id, err := r.LastInsertId()
if err != nil {
fmt.Println("exec failed,", err)
//回滚
conn.Rollback()
return
}
fmt.Println("insert succ:", id)
//提交事务
conn.Commit()
}
