* Flux 0.7.0+

InfluxDB support

`sort()` orders rows in each input table based on values in specified columns.

#### Output data

One output table is produced for each input table.
Output tables have the same schema as their corresponding input tables.

#### Sorting with null values

When `desc: false`, null values are last in the sort order.
When `desc: true`, null values are first in the sort order.

##### Function type signature

```js
(<-tables: stream[A], ?columns: [string], ?desc: bool) => stream[A] where A: Record
```

For more information, see [Function type signatures](/flux/v0/function-type-signatures/).

## Parameters

### columns

List of columns to sort by. Default is `["_value"]`.

Sort precedence is determined by list order (left to right).

### desc

Sort results in descending order. Default is `false`.

### tables

Input data. Default is piped-forward data (`<-`).

## Examples

### Sort values in ascending order

```js
import "sampledata"

sampledata.int()
    |> sort()
```
