There is a way to do this function more generic?

I would like to make this function more generic (with a "for")

func (e example) ScanRow(rows *sql.Rows) (example, error) {
    val := reflect.ValueOf(e)
    test := make([]interface{}, val.Type().NumField())

    test[0] = &e.Id
    test[1] = &e.CreatedAt
    test[2] = &e.Text
    test[3] = &e.AuthorId
    test[4] = &e.CategoryId

    if err := rows.Scan(test[0], test[1], test[2], test[3], test[4]); err != nil {
        return e, err
    }
    return e, nil
}

Here is the struct example:

type example struct {
    Id      int `json:"id"`
    CreatedAt   string `json:"created_at"`
    Text        string `json:"text"`
    AuthorId    int `json:"author_id"`
    CategoryId  int `json:"category_id"`
}

Do you think it's possible ? I try to find a way to do that but i am lost...
