# CSVWithNamesAndTypes

| Вход | Выход | Псевдоним |
| ---- | ----- | --------- |
| ✔    | ✔     |           |

<div id="description">
  ## Описание
</div>

Также выводятся две строки заголовка с именами столбцов и типами данных, аналогично [TabSeparatedWithNamesAndTypes](/ru/reference/formats/TabSeparated/TabSeparatedWithNamesAndTypes).

<div id="example-usage">
  ## Пример использования

<div id="inserting-data">
  ### Вставка данных
</div>

<Tip>
  Начиная с [версии](https://github.com/ClickHouse/ClickHouse/releases) 23.1, ClickHouse автоматически определяет заголовки в CSV-файлах при использовании формата `CSV`, поэтому использовать `CSVWithNames` или `CSVWithNamesAndTypes` не требуется.
</Tip>

Возьмем следующий CSV-файл с именем `football_types.csv`:

```csv theme={null}
date,season,home_team,away_team,home_team_goals,away_team_goals
Date,Int16,LowCardinality(String),LowCardinality(String),Int8,Int8
2022-04-30,2021,Sutton United,Bradford City,1,4
2022-04-30,2021,Swindon Town,Barrow,2,1
2022-04-30,2021,Tranmere Rovers,Oldham Athletic,2,0
2022-05-02,2021,Salford City,Mansfield Town,2,2
2022-05-02,2021,Port Vale,Newport County,1,2
2022-05-07,2021,Barrow,Northampton Town,1,3
2022-05-07,2021,Bradford City,Carlisle United,2,0
2022-05-07,2021,Bristol Rovers,Scunthorpe United,7,0
2022-05-07,2021,Exeter City,Port Vale,0,1
2022-05-07,2021,Harrogate Town A.F.C.,Sutton United,0,2
2022-05-07,2021,Hartlepool United,Colchester United,0,2
2022-05-07,2021,Leyton Orient,Tranmere Rovers,0,1
2022-05-07,2021,Mansfield Town,Forest Green Rovers,2,2
2022-05-07,2021,Newport County,Rochdale,0,2
2022-05-07,2021,Oldham Athletic,Crawley Town,3,3
2022-05-07,2021,Stevenage Borough,Salford City,4,2
2022-05-07,2021,Walsall,Swindon Town,0,3
```

Создайте таблицу:

```sql theme={null}
CREATE TABLE football
(
    `date` Date,
    `season` Int16,
    `home_team` LowCardinality(String),
    `away_team` LowCardinality(String),
    `home_team_goals` Int8,
    `away_team_goals` Int8
)
ENGINE = MergeTree
ORDER BY (date, home_team);
```

Вставьте данные в формате `CSVWithNamesAndTypes`:

```sql theme={null}
INSERT INTO football FROM INFILE 'football_types.csv' FORMAT CSVWithNamesAndTypes;
```

<div id="reading-data">
  ### Чтение данных
</div>

Считывайте данные в формате `CSVWithNamesAndTypes`:

```sql theme={null}
SELECT *
FROM football
FORMAT CSVWithNamesAndTypes
```

Результатом будет CSV с двумя строками заголовков: с именами столбцов и типами:

```csv theme={null}
"date","season","home_team","away_team","home_team_goals","away_team_goals"
"Date","Int16","LowCardinality(String)","LowCardinality(String)","Int8","Int8"

  ## Настройки формата
</div>

<Note>
  Если параметр [input\_format\_with\_names\_use\_header](/ru/reference/settings/formats#input_format_with_names_use_header) установлен в `1`,
  столбцы из входных данных будут сопоставлены со столбцами таблицы по именам, а столбцы с неизвестными именами будут пропущены, если параметр [input\_format\_skip\_unknown\_fields](/ru/reference/settings/formats#input_format_skip_unknown_fields) установлен в `1`.
  В противном случае первая строка будет пропущена.
</Note>

<Note>
  Если параметр [input\_format\_with\_types\_use\_header](/ru/reference/settings/formats#input_format_with_types_use_header) установлен в `1`,
  типы из входных данных будут сравниваться с типами соответствующих столбцов таблицы. В противном случае вторая строка будет пропущена.
