# Dosya {#file}
Bir dosyadan bir tablo oluşturur. Bu tablo işlevi benzer [url](url.md) ve [hdf'ler](hdfs.md) biri.
``` sql
file(path, format, structure)
```
**Giriş parametreleri**
- `path` — The relative path to the file from [user\_files\_path](../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-user_files_path). Readonly modunda glob'ları takip eden dosya desteğine giden yol: `*`, `?`, `{abc,def}` ve `{N..M}` nerede `N`, `M` — numbers, \``'abc', 'def'` — strings.
- `format` — The [biçimli](../../interfaces/formats.md#formats) dosya.
- `structure` — Structure of the table. Format `'column1_name column1_type, column2_name column2_type, ...'`.
**Döndürülen değer**
Belirtilen dosyada veri okumak veya yazmak için belirtilen yapıya sahip bir tablo.
**Örnek**
Ayar `user_files_path` ve dosyanın içeriği `test.csv`:
``` bash
$ grep user_files_path /etc/clickhouse-server/config.xml
<user_files_path>/var/lib/clickhouse/user_files/</user_files_path>
$ cat /var/lib/clickhouse/user_files/test.csv
1,2,3
3,2,1
78,43,45
```
Tablo fromdan`test.csv` ve ondan ilk iki satır seçimi:
``` sql
SELECT *
FROM file('test.csv', 'CSV', 'column1 UInt32, column2 UInt32, column3 UInt32')
LIMIT 2
```
``` text
┌─column1─┬─column2─┬─column3─┐
│ 1 │ 2 │ 3 │
│ 3 │ 2 │ 1 │
└─────────┴─────────┴─────────┘
```
``` sql
-- getting the first 10 lines of a table that contains 3 columns of UInt32 type from a CSV file
SELECT * FROM file('test.csv', 'CSV', 'column1 UInt32, column2 UInt32, column3 UInt32') LIMIT 10
```
**Yolda Globs**
Birden çok yol bileşenleri globs olabilir. İşlenmek için dosya var olmalı ve tüm yol deseniyle eşleşmelidir (sadece sonek veya önek değil).
- `*` — Substitutes any number of any characters except `/` boş dize dahil.
- `?` — Substitutes any single character.
- `{some_string,another_string,yet_another_one}` — Substitutes any of strings `'some_string', 'another_string', 'yet_another_one'`.
- `{N..M}` — Substitutes any number in range from N to M including both borders.
İle yapılar `{}` benzer olan [uzaktan masa fonksiyonu](../../sql-reference/table-functions/remote.md)).
**Örnek**
1. Aşağıdaki göreli yollara sahip birkaç dosyamız olduğunu varsayalım:
- some\_dir/some\_file\_1
- some\_dir/some\_file\_2
- some\_dir/some\_file\_3
- another\_dir/some\_file\_1
- another\_dir/some\_file\_2
- another\_dir/some\_file\_3
1. Bu dosyalardaki satır miktarını sorgula:
<!-- -->
``` sql
SELECT count(*)
FROM file('{some,another}_dir/some_file_{1..3}', 'TSV', 'name String, value UInt32')
```
1. Bu iki dizinin tüm dosyalarındaki satır miktarını sorgula:
<!-- -->
``` sql
SELECT count(*)
FROM file('{some,another}_dir/*', 'TSV', 'name String, value UInt32')
```
!!! warning "Uyarıcı"
Dosya listenizde önde gelen sıfırlar içeren sayı aralıkları varsa, her basamak için parantez içeren yapıyı ayrı ayrı kullanın veya kullanın `?`.
**Örnek**
Adlı dosy thealardan verileri sorgu thelamak `file000`, `file001`, … , `file999`:
``` sql
SELECT count(*)
FROM file('big_dir/file{0..9}{0..9}{0..9}', 'CSV', 'name String, value UInt32')
```
## Sanal Sütunlar {#virtual-columns}
