刪除預留項目群組

從 BigQuery Reservation API 刪除預留項目群組。只有在預留項目群組不含任何子項預留項目時，才能刪除該群組。

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 {ReservationServiceClient} =
  require('@google-cloud/bigquery-reservation').v1;
const {status} = require('@grpc/grpc-js');

const client = new ReservationServiceClient();

/**
 * Deletes the specified reservation group.
 * A reservation group can only be deleted if it contains no reservations.
 * @param {string} projectId Google Cloud Project ID, for example 'example-project-id'.
 * @param {string} location Google Cloud Location, for example 'us-central1'.
 * @param {string} reservationGroupId The ID of the reservation group to delete, for example 'example-reservation-group'.
 */
async function deleteReservationGroup(
  projectId,
  location = 'us-central1',
  reservationGroupId = 'example-group-reservation',
) {
  const request = {
    name: client.reservationGroupPath(projectId, location, reservationGroupId),
  };

  try {
    await client.deleteReservationGroup(request);
    console.log(`Deleted reservation group: ${reservationGroupId}`);
  } catch (err) {
    if (err.code === status.NOT_FOUND) {
      console.log(
        `Reservation group ${reservationGroupId} does not exist in location ${location} of project ${projectId}.`,
      );
    } else {
      console.error(
        `Error deleting reservation group ${reservationGroupId}:`,
        err,
      );
    }
  }
}

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.cloud import bigquery_reservation_v1


client = bigquery_reservation_v1.ReservationServiceClient()

    Note that a reservation group cannot be deleted if it contains any
    reservations.

    Args:
        project_id: The Google Cloud project ID.
        location: The geographic location of the reservation group, for example, us-central1.
        reservation_group_id: The ID of the reservation group to delete.
    """
    name = client.reservation_group_path(project_id, location, reservation_group_id)

    try:

        print(f"Deleted reservation group: '{name}'")
    except NotFound:
        print(f"Reservation group '{name}' not found.")
