# Project Operator

## Overview

Choose which fields to return, while optionally renaming them and/or calculating new ones using `project`.

```kusto
| project [<dest>=]<expression>[, ...]
```

## Examples

{% hint style="info" %}
Example data

```kusto
let aws_alb = datatable [
  {"type": "https", "p_event_time": "2023-09-16 05:45:34.863", "elb": "app/http-ingest-alb/71c6e92aca17df92", "clientIp": "192.168.11.34", "elbStatusCode": 200, "sentBytes": 329, "requestHttpVersion": "HTTP/1.1", "sslCipher": "TLS_AES_128_GCM_SHA256", "userAgent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/118.0.0.0 Safari/537.36"},
  {"type": "https", "p_event_time": "2023-09-16 05:59:04.058", "elb": "app/http-ingest-alb/71c6e92aca17df92", "clientIp": "192.168.1.1", "elbStatusCode": 403, "sentBytes": 167, "requestHttpVersion": "HTTP/1.1", "sslCipher": "TLS_AES_128_GCM_SHA256", "userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0.0.0 Safari/537.36"},

];
```

{% endhint %}

### Return only certain fields

The query below returns only the `p_event_time`and `clientIp` fields:

```kusto
aws_alb
| project p_event_time, clientIp
```

| EVENT                                                                        |
| ---------------------------------------------------------------------------- |
| `{ "p_event_time": "2023-09-16 05:45:34.863", "clientIp": "192.168.11.34" }` |
| `{ "p_event_time": "2023-09-16 05:59:04.058", "clientIp": "192.168.1.1" }`   |
| `{ "p_event_time": "2023-09-16 05:36:09.017", "clientIp": "10.168.22.7" }`   |
| `{ "p_event_time": "2023-09-16 05:36:09.017", "clientIp": "10.168.22.1" }`   |

### Rename fields

```kusto
aws_alb
| project p_event_time, client=clientIp
```

| EVENT                                                                      |
| -------------------------------------------------------------------------- |
| `{ "p_event_time": "2023-09-16 05:45:34.863", "client": "192.168.11.34" }` |
| `{ "p_event_time": "2023-09-16 05:59:04.058", "client": "192.168.1.1" }`   |
| `{ "p_event_time": "2023-09-16 05:36:09.017", "client": "10.168.22.7" }`   |
| `{ "p_event_time": "2023-09-16 05:36:09.017", "client": "10.168.22.1" }`   |

### Calculate new fields

This functionality is similar to the [`extend`](/pantherflow/operators/extend.md) operator.

```kusto
aws_alb
| project p_event_time, client = clientIp,
          is_http_11 = requestHttpVersion == 'HTTP/1.1'
```

| EVENT                                                                                          |
| ---------------------------------------------------------------------------------------------- |
| `{ "p_event_time": "2023-09-16 05:45:34.863", "client": "192.168.11.34", "is_http_11": true }` |
| `{ "p_event_time": "2023-09-16 05:59:04.058", "client": "192.168.1.1", "is_http_11": true }`   |
| `{ "p_event_time": "2023-09-16 05:36:09.017", "client": "10.168.22.7", "is_http_11": false }`  |
| `{ "p_event_time": "2023-09-16 05:36:09.017", "client": "10.168.22.1", "is_http_11": true }`   |
