程式碼範例

Go

在試行這個範例之前，請先按照 BigQuery 快速入門導覽課程：使用用戶端程式庫中的 Go 設定說明進行操作。詳情請參閱 BigQuery Go 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機制」。

import (
	"context"
	"fmt"

	datatransfer "cloud.google.com/go/bigquery/datatransfer/apiv1"
	"cloud.google.com/go/bigquery/datatransfer/apiv1/datatransferpb"
)

// deleteScheduledQuery delete a scheduled query based on
// the config ID, stopping any future runs.
// transferConfigID follows the format:
//
//	`projects/{project_id}/locations/{location_id}/transferConfigs/{config_id}`
//	or `projects/{project_id}/transferConfigs/{config_id}`
func deleteScheduledQuery(transferConfigID string) error {
	// transferConfigID := "projects/{project_id}/transferConfigs/{config_id}"
	ctx := context.Background()
	dtc, err := datatransfer.NewClient(ctx)
	if err != nil {
		return fmt.Errorf("datatransfer.NewClient: %w", err)
	}
	defer dtc.Close()

	req := &datatransferpb.DeleteTransferConfigRequest{
		Name: transferConfigID,
	}
	err = dtc.DeleteTransferConfig(ctx, req)
	if err != nil {
		return fmt.Errorf("dtc.DeleteTransferConfig: %w", err)
	}

	return nil
}

Java

在試行這個範例之前，請先按照 BigQuery 快速入門導覽課程：使用用戶端程式庫中的 Java 設定說明進行操作。詳情請參閱 BigQuery Java 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機制」。

import com.google.api.gax.rpc.ApiException;
import com.google.cloud.bigquery.datatransfer.v1.DataTransferServiceClient;
import com.google.cloud.bigquery.datatransfer.v1.DeleteTransferConfigRequest;
import java.io.IOException;

// Sample to delete a scheduled query
public class DeleteScheduledQuery {

  public static void main(String[] args) throws IOException {
    // TODO(developer): Replace these variables before running the sample.
    // i.e projects/{project_id}/transferConfigs/{config_id}` or
    // `projects/{project_id}/locations/{location_id}/transferConfigs/{config_id}`
    String name = "MY_CONFIG_ID";
    deleteScheduledQuery(name);
  }

  public static void deleteScheduledQuery(String name) throws IOException {
    try (DataTransferServiceClient dataTransferServiceClient = DataTransferServiceClient.create()) {
      DeleteTransferConfigRequest request =
          DeleteTransferConfigRequest.newBuilder().setName(name).build();
      dataTransferServiceClient.deleteTransferConfig(request);
      System.out.print("Scheduled query deleted successfully.\n");
    } catch (ApiException ex) {
      System.out.print("Scheduled query was not deleted." + ex.toString());
    }
  }
}
