# `last`

## Description

The `last` keyword specifies how far back in time a query should go, defined by a given `interval`.

Note

The value of the given `interval` MUST be non-negative.

## Syntax

```dataprime
source (logs|spans) last <interval>
```

## Example

The `last` keyword is simple to employ for both `logs` and `spans`.

```dataprime
source logs last 1h
source spans last 1d
```

Given the timerange in the Coralogix interface is `Last 1 Hour`, and we run the following query:

```dataprime
source spans last 1d
```

Then the result of this query will be the `spans` from the last 1 day. **There is no relationship between the `interval` in the `last` keyword and the timerange in the Coralogix UI.**

### Try it yourself

Open up your Coralogix explore screen and paste in the following query:

```dataprime
source logs last 1d
```
