# TSKV

## Описание
Аналогично формату [`TabSeparated`](/ru/reference/formats/TabSeparated/TabSeparated), но выводит значение в формате `name=value`.
Имена экранируются так же, как и в формате [`TabSeparated`](/ru/reference/formats/TabSeparated/TabSeparated), при этом символ `=` тоже экранируется.
```text theme={null}
SearchPhrase= count()=8267016
SearchPhrase=bathroom interior design count()=2166
SearchPhrase=clickhouse count()=1655
SearchPhrase=2014 spring fashion count()=1549
SearchPhrase=freeform photos count()=1480

```
```sql title="Query" theme={null}
SELECT * FROM t_null FORMAT TSKV
```
```text title="Response" theme={null}

```
При большом количестве небольших столбцов этот формат неэффективен, и обычно нет смысла его использовать.
Тем не менее, по эффективности он не уступает формату [`JSONEachRow`](/ru/reference/formats/JSON/JSONEachRow).
При парсинге поддерживается любой порядок значений в разных столбцах.
Некоторые значения можно опускать, так как они считаются равными значениям по умолчанию.
В этом случае в качестве значений по умолчанию используются нули и пустые строки.
Сложные значения, которые можно было бы указать в таблице, в качестве значений по умолчанию не поддерживаются.
При парсинге также допускается добавление дополнительного поля `tskv` без знака равенства и без значения. Это поле игнорируется.
Во время импорта столбцы с неизвестными именами будут пропущены,
если для настройки [`input_format_skip_unknown_fields`](/ru/reference/settings/formats#input_format_skip_unknown_fields) установлено значение `1`.
[NULL](/ru/reference/syntax) записывается как `\N`.
## Пример использования
### Вставка данных
Используя следующий файл tskv с именем `football.tskv`:
```tsv theme={null}

```
Выполните вставку данных:
```sql theme={null}
INSERT INTO football FROM INFILE 'football.tskv' FORMAT TSKV;
```
### Чтение данных
Прочитайте данные в формате `TSKV`:
```sql theme={null}
SELECT *
FROM football
FORMAT TSKV
```
Вывод будет в формате с табуляцией в качестве разделителя и двумя строками заголовка с именами столбцов и типами:
```tsv theme={null}
