public void deleteTable() { System.out.println("Deleting table"); final DeleteTableRequest deleteTableRequest = new DeleteTableRequest(); deleteTableRequest.setDatabaseName(DATABASE_NAME); deleteTableRequest.setTableName(TABLE_NAME); try { DeleteTableResult result = amazonTimestreamWrite.deleteTable(deleteTableRequest); System.out.println("Delete table status: " + result.getSdkHttpMetadata().getHttpStatusCode()); } catch (final ResourceNotFoundException e) { System.out.println("Table " + TABLE_NAME + " doesn't exist = " + e); throw e; } catch (final Exception e) { System.out.println("Could not delete table " + TABLE_NAME + " = " + e); throw e; } }
- Java v2
-
public void deleteTable() { System.out.println("Deleting table"); final DeleteTableRequest deleteTableRequest = DeleteTableRequest.builder() .databaseName(DATABASE_NAME).tableName(TABLE_NAME).build(); try { DeleteTableResponse response = timestreamWriteClient.deleteTable(deleteTableRequest); System.out.println("Delete table status: " + response.sdkHttpResponse().statusCode()); } catch (final ResourceNotFoundException e) { System.out.println("Table " + TABLE_NAME + " doesn't exist = " + e); throw e; } catch (final Exception e) { System.out.println("Could not delete table " + TABLE_NAME + " = " + e); throw e; } }
- Go
-
deleteTableInput := ×treamwrite.DeleteTableInput{ DatabaseName: aws.String(*databaseName), TableName: aws.String(*tableName), } _, err = writeSvc.DeleteTable(deleteTableInput) if err != nil { fmt.Println("Error:") fmt.Println(err) } else { fmt.Println("Table deleted", *tableName) }
- Python
-
def delete_table(self): print("Deleting Table") try: result = self.client.delete_table(DatabaseName=Constant.DATABASE_NAME, TableName=Constant.TABLE_NAME) print("Delete table status [%s]" % result['ResponseMetadata']['HTTPStatusCode']) except self.client.exceptions.ResourceNotFoundException: print("Table [%s] doesn't exist" % Constant.TABLE_NAME) except Exception as err: print("Delete table failed:", err)

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 DeleteTableCommand 和 DeleteTable。
import { TimestreamWriteClient, DeleteTableCommand } from "@aws-sdk/client-timestream-write"; const writeClient = new TimestreamWriteClient({ region: "us-east-1" }); const params = { DatabaseName: "testDbFromNode", TableName: "testTableFromNode" }; const command = new DeleteTableCommand(params); try { const data = await writeClient.send(command); console.log("Deleted table"); } catch (error) { if (error.code === 'ResourceNotFoundException') { console.log(`Table ${params.TableName} or Database ${params.DatabaseName} doesn't exist.`); } else { console.log("Delete table 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 deleteTable() { console.log("Deleting Table"); const params = { DatabaseName: constants.DATABASE_NAME, TableName: constants.TABLE_NAME }; const promise = writeClient.deleteTable(params).promise(); await promise.then( function (data) { console.log("Deleted table"); }, function(err) { if (err.code === 'ResourceNotFoundException') { console.log(`Table ${params.TableName} or Database ${params.DatabaseName} doesn't exists.`); } else { console.log("Delete table failed.", err); throw err; } } ); }
- .NET
-
public async Task DeleteTable() { Console.WriteLine("Deleting table"); try { var deleteTableRequest = new DeleteTableRequest { DatabaseName = Constants.DATABASE_NAME, TableName = Constants.TABLE_NAME }; DeleteTableResponse response = await writeClient.DeleteTableAsync(deleteTableRequest); Console.WriteLine($"Table {Constants.TABLE_NAME} delete request status: {response.HttpStatusCode}"); } catch (ResourceNotFoundException) { Console.WriteLine($"Table {Constants.TABLE_NAME} does not exists"); } catch (Exception e) { Console.WriteLine("Exception while deleting table:" + e.ToString()); } }
