# url
|
||
|
||
`url(URL, format, structure)` - возвращает таблицу со столбцами, указанными в
|
||
`structure`, созданную из данных находящихся по `URL` в формате `format`.
|
||
|
||
URL - адрес, по которому сервер принимает `GET` и/или `POST` запросы по
|
||
протоколу HTTP или HTTPS.
|
||
|
||
format - [формат](../../interfaces/formats.md#formats) данных.
|
||
|
||
structure - структура таблицы в форме `'UserID UInt64, Name String'`. Определяет имена и типы столбцов.
|
||
|
||
**Пример**
|
||
|
||
```sql
|
||
-- получение 3-х строк таблицы, состоящей из двух колонк типа String и UInt32 от сервера, отдающего данные в формате CSV
|
||
SELECT * FROM url('http://127.0.0.1:12345/', CSV, 'column1 String, column2 UInt32') LIMIT 3
|
||
```
