# Project 연산자

## 개요

옵션으로 이름을 변경하고/하거나 새 필드를 계산하면서 반환할 필드를 선택합니다. 다음을 사용하여 `project`.

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

## 예제

{% hint style="info" %}
예제 데이터

```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"},

### 특정 필드만 반환

아래 쿼리는 다음 항목만 반환합니다. `p_event_time`및 `clientIp` 필드:

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

| 이벤트                                                                          |
| ---------------------------------------------------------------------------- |
| `{ "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" }`   |

### 필드 이름 변경

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

| 이벤트                                                                        |
| -------------------------------------------------------------------------- |
| `{ "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" }`   |

### 새 필드 계산

이 기능은 다음과 유사합니다. [`extend`](/ko/pantherflow/operators/extend.md) 연산자.

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

| 이벤트                                                                                            |
| ---------------------------------------------------------------------------------------------- |
| `{ "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 }`   |
