Go 语言里的 SQL 优雅写法？

go get -u github.com/jmoiron/sqlx

import (
    _ "github.com/go-sql-driver/mysql"
    "github.com/jmoiron/sqlx"
)

func main() {
    db, err := sqlx.Connect("mysql", "user:password@tcp(localhost:3306)/dbname")
    if err != nil {
        log.Fatalln(err)
    }
    defer db.Close()
}

type User struct {
    ID        int64  `db:"id"`
    Name      string `db:"name"`
    Email     string `db:"email"`
    CreatedAt time.Time `db:"created_at"`
}

var user User
err := db.Get(&user, "SELECT * FROM users WHERE id = ?", 1)
if err != nil {
    log.Fatalln(err)
}

var users []User
err := db.Select(&users, "SELECT * FROM users")
if err != nil {
    log.Fatalln(err)
}

_, err := db.Exec("INSERT INTO users (name, email) VALUES (?, ?)", "John Doe", "john@example.com")
if err != nil {
    log.Fatalln(err)
}

_, err := db.Exec("UPDATE users SET name = ?, email = ? WHERE id = ?", "Jane Doe", "jane@example.com", 1)
if err != nil {
    log.Fatalln(err)
}

_, err := db.Exec("DELETE FROM users WHERE id = ?", 1)
if err != nil {
    log.Fatalln(err)
}
