# Functions for Working with Files

## file

Reads file as a String. The file content is not parsed, so any information is read as one string and placed into the specified column.

**Syntax**

``` sql
file(path[, default])
```

**Arguments**

-   `path` — The relative path to the file from [user_files_path](../../operations/server-configuration-parameters/settings.md#server_configuration_parameters-user_files_path). Path to file support following wildcards: `*`, `?`, `{abc,def}` and `{N..M}` where `N`, `M` — numbers, `'abc', 'def'` — strings.
-   `default` — The value that will be returned in the case when a file does not exist or cannot be accessed. Data types supported: [String](../../sql-reference/data-types/string.md) and [NULL](../../sql-reference/syntax.md#null-literal).

**Example**

Inserting data from files a.txt and b.txt into a table as strings:

Query:

``` sql
INSERT INTO table SELECT file('a.txt'), file('b.txt');
```
