下列程式碼片段用於 AWS SDK JavaScript v3。如需如何安裝用戶端和用量的詳細資訊,請參閱 Timestream Write Client - AWS SDK for JavaScript v3。
另請參閱類別 DeleteDatabaseCommand 和 DeleteDatabase。
import { TimestreamWriteClient, DeleteDatabaseCommand } from "@aws-sdk/client-timestream-write"; const writeClient = new TimestreamWriteClient({ region: "us-east-1" }); const params = { DatabaseName: "testDbFromNode" }; const command = new DeleteDatabaseCommand(params); try { const data = await writeClient.send(command); console.log("Deleted database"); } catch (error) { if (error.code === 'ResourceNotFoundException') { console.log(`Database ${params.DatabaseName} doesn't exists.`); } else { console.log("Delete database failed.", error); throw error; } }
下列程式碼片段使用 AWS SDK JavaScript V2 樣式的 。它以 Node.js 範例應用程式為基礎,適用於 上的 LiveAnalytics 應用程式 GitHub
。 async function deleteDatabase() { console.log("Deleting Database"); const params = { DatabaseName: constants.DATABASE_NAME }; const promise = writeClient.deleteDatabase(params).promise(); await promise.then( function (data) { console.log("Deleted database"); }, function(err) { if (err.code === 'ResourceNotFoundException') { console.log(`Database ${params.DatabaseName} doesn't exists.`); } else { console.log("Delete database failed.", err); throw err; } } ); }
- .NET
-
public async Task DeleteDatabase() { Console.WriteLine("Deleting database"); try { var deleteDatabaseRequest = new DeleteDatabaseRequest { DatabaseName = Constants.DATABASE_NAME }; DeleteDatabaseResponse response = await writeClient.DeleteDatabaseAsync(deleteDatabaseRequest); Console.WriteLine($"Database {Constants.DATABASE_NAME} delete request status:{response.HttpStatusCode}"); } catch (ResourceNotFoundException) { Console.WriteLine($"Database {Constants.DATABASE_NAME} does not exists"); } catch (Exception e) { Console.WriteLine("Exception while deleting database:" + e.ToString()); } }
