5단계: Power BI 테이블에 행 추가Step 5: Add rows to a Power BI table

이 문서는 데이터 집합에 데이터를 푸시하는 단계별 연습의 일부입니다.This article is part of a step-by-step walkthrough to push data into a dataset.

데이터 집합에 데이터 푸시의 4단계Power BI 테이블에 행을 추가할 데이터 집합 가져오기에서는 데이터 집합 가져오기 작업 및 Newtonsoft.Json을 사용하여 데이터 집합 ID를 가져왔습니다. 이 단계에서는 행 추가 작업에 데이터 집합 ID를 사용하여 Power BI 데이터 집합에 행을 추가합니다.In step 4 of Push data into a dataset, Get a dataset to add rows into a Power BI table, you used the Get Datasets operation and Newtonsoft.Json to get a dataset id. In this step, you use the dataset id with the Add Rows operation to add rows to a Power BI dataset.

행 추가 작업을 호출하면 데이터 집합에 행이 추가됩니다.When you call the Add Rows operation, you add rows to a dataset.

Power BI API를 사용하여 데이터 집합에 행을 추가하는 방법은 다음과 같습니다.Here's how to add rows to a dataset using the Power BI API.

참고

시작하기 전에 데이터 집합에 데이터 푸시의 이전 단계를 수행해야 합니다.Before you get started, make sure you have followed the previous steps in the push data into a dataset walkthrough.

  1. 2단계: 데이터 푸시 연습, 인증 액세스 토큰 가져오기에서 만든 콘솔 응용 프로그램 프로젝트에 아래 코드를 추가합니다.In the Console Application project you created in Step 2: Walkthrough to push data, Get an authentication access token, add the code below.
  2. 콘솔 앱을 실행하고 Power BI 계정에 로그인합니다.Run the Console App, and login to your Power BI account. 추가된 행 이 콘솔 창에 표시됩니다.You should see Rows Added in the Console Window. Power BI에 로그인하여 데이터 집합에 추가된 행을 볼 수도 있습니다.You can also login to Power BI to see the rows added to the dataset.
