程式碼範例

Node.js

在試用這個範例之前，請先按照「使用用戶端程式庫的 BigQuery 快速入門導覽課程」中的 Node.js 設定說明操作。詳情請參閱 BigQuery Node.js API 參考說明文件。

如要向 BigQuery 進行驗證，請設定應用程式預設憑證。詳情請參閱「設定用戶端程式庫的驗證作業」。

const {DataPolicyServiceClient} =
  require('@google-cloud/bigquery-datapolicies').v2;
const {status} = require('@grpc/grpc-js');

const client = new DataPolicyServiceClient();

/**
 * Deletes a data policy from the BigQuery Data Policy API, which is identified by its project ID, location, and data policy ID.
 *
 * @param {string} projectId The Google Cloud project ID.
 * @param {string} location The Google Cloud location (For example, 'us').
 * @param {string} dataPolicyId The ID of the data policy to delete (For example, 'example-data-policy').
 */
async function deleteDataPolicy(projectId, location, dataPolicyId) {
  const name = client.dataPolicyPath(projectId, location, dataPolicyId);

  const request = {
    name,
  };

  try {
    await client.deleteDataPolicy(request);
    console.log(`Successfully deleted data policy: ${name}`);
  } catch (err) {
    if (err.code === status.NOT_FOUND) {
      console.error(
        `Data policy ${name} not found. Make sure the data policy ID and location are correct.`,
      );
    } else {
      console.error(`Error deleting data policy ${name}:`, err.message);
    }
  }
}

Python

在試用這個範例之前，請先按照「使用用戶端程式庫的 BigQuery 快速入門導覽課程」中的 Python 設定說明操作。詳情請參閱 BigQuery Python API 參考說明文件。

如要向 BigQuery 進行驗證，請設定應用程式預設憑證。詳情請參閱「設定用戶端程式庫的驗證作業」。

from google.api_core import exceptions as core_exceptions
from google.cloud import bigquery_datapolicies_v2

client = bigquery_datapolicies_v2.DataPolicyServiceClient()

    Args:

        location: The location of the data policy (for example, "us").
        data_policy_id: The ID of the data policy to delete.
    """

    name = client.data_policy_path(
        project=project_id, location=location, data_policy=data_policy_id
    )

    try:

        print(f"Successfully deleted data policy: {name}")
    except core_exceptions.NotFound:
        print(f"Data policy '{name}' not found. It may have already been deleted.")
    except Exception as e:
        print(f"Error deleting data policy '{name}': {e}")
