怎麼寫 MySQL

package main

import (
    "database/sql"
    "fmt"

    _ "github.com/go-sql-driver/mysql"
)

func main() {
    // connection
    db, err := sql.Open("mysql", "root:password@tcp(127.0.0.1:3306)/blog_service")
    check(err)
    defer db.Close()

    // query rows
    rows, err := db.Query("SELECT id FROM blog_service.blog_article")
    check(err)

    for rows.Next() {
        var id int
        err = rows.Scan(&id)
        check(err)
        fmt.Println(id)
    }
}

func check(err error) {
    if err != nil {
        panic(err)
    }
}
