A consulta é o conjunto de pares chave-valor que vai depois de `?` na URL, separado pelo caractere `&`.

Por exemplo, na URL:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

...os parâmetros da consulta são:

* `skip`: com o valor `0`
* `limit`: com o valor `10`

Como eles são parte da URL, eles são "naturalmente" strings.

Por ejemplo, en la URL:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

...los parámetros de query son:

* `skip`: con un valor de `0`
* `limit`: con un valor de `10`

Como son parte de la URL, son "naturalmente" strings.

Caso um cliente tente enviar alguns dados **extras** nos **parâmetros de consulta**, eles receberão um retorno de **erro**.

Por exemplo, se o cliente tentar enviar um parâmetro de consulta `tool` com o valor `plumbus`, como:

```http
https://example.com/items/?limit=10&tool=plumbus
```

	user1 := User{Name: "RowUser1", Age: 1}
	user2 := User{Name: "RowUser2", Age: 10}
	user3 := User{Name: "RowUser3", Age: 20}
	DB.Save(&user1).Save(&user2).Save(&user3)

	row := DB.Table("users").Where("name = ?", user2.Name).Select("age").Row()

	var age int64
	if err := row.Scan(&age); err != nil {
		t.Fatalf("Failed to scan age, got %v", err)
	}

	if age != 10 {
		t.Errorf("Scan with Row, age expects: %v, got %v", user2.Age, age)
	}
