标题: GO操作Mysql数据库
1、使用github.com/go-sql-driver/mysql和github.com/jmoiron/sqlx这个驱动包和工具类，打开cmd窗口输入：go get github.com/go-sql-driver/mysql和go get github.com/jmoiron/sqlx，会下载到你的GOPATH路径的src 下

2、导入驱动包
import ( "database/sql" _ "github.com/go-sql-driver/mysql")
3、链接数据库
db, err := sql.Open("mysql",       "user:password@tcp(127.0.0.1:3306)/hello")
  if err != nil {
   log.Fatal(err)
  }
  defer db.Close()

4、插入数据
r, err := Db.Exec("insert into person(username,sex,email)values(?,?,?)", "stu004", "man", "stu001@qq.com")
if err != nil {
  fmt.Println("exec1 failed,", err)
  return
}
id, err := r.LastInsertId()//返回插入数据ID
if err != nil {
  fmt.Println("exec2 failed,", err)
  return
}
fmt.Println("insert succ:", id)

5、查询数据
var person []Person
err := Db.Select(&person, "select * from person")
if err != nil {
  fmt.Println("exec_select failed,", err)
  return
}
fmt.Println("select succ:", person)

6、更新数据
_, err := Db.Exec("update person set username=? where user_id=?", "stu011", 1)
if err != nil {
  fmt.Println("exec_update failed,", err)
  return
}
fmt.Println("更新成功")

7、删除数据
_, err := Db.Exec("delete from person where user_id=?", 10)
if err != nil {
  fmt.Println("exec_delete failed,", err)
  return
}
fmt.Println("删除成功")
