Excluir banco de dados

É possível usar o seguinte trecho de código para excluir um banco de dados.

nota

Esses trechos de código são baseados em aplicativos de amostra completos no GitHub. Para obter mais informações sobre como criar aplicativos de amostra, consulte Aplicação de exemplo.

Java

    public void deleteDatabase() {
        System.out.println("Deleting database");
        final DeleteDatabaseRequest deleteDatabaseRequest = new DeleteDatabaseRequest();
        deleteDatabaseRequest.setDatabaseName(DATABASE_NAME);
        try {
            DeleteDatabaseResult result =
                    amazonTimestreamWrite.deleteDatabase(deleteDatabaseRequest);
            System.out.println("Delete database status: " + result.getSdkHttpMetadata().getHttpStatusCode());
        } catch (final ResourceNotFoundException e) {
            System.out.println("Database " + DATABASE_NAME + " doesn't exist = " + e);
            throw e;
        } catch (final Exception e) {
            System.out.println("Could not delete Database " + DATABASE_NAME + " = " + e);
            throw e;
        }
    }

Java v2

    public void deleteDatabase() {
        System.out.println("Deleting database");
        final DeleteDatabaseRequest deleteDatabaseRequest = new DeleteDatabaseRequest();
        deleteDatabaseRequest.setDatabaseName(DATABASE_NAME);
        try {
            DeleteDatabaseResult result =
                    amazonTimestreamWrite.deleteDatabase(deleteDatabaseRequest);
            System.out.println("Delete database status: " + result.getSdkHttpMetadata().getHttpStatusCode());
        } catch (final ResourceNotFoundException e) {
            System.out.println("Database " + DATABASE_NAME + " doesn't exist = " + e);
            throw e;
        } catch (final Exception e) {
            System.out.println("Could not delete Database " + DATABASE_NAME + " = " + e);
            throw e;
        }
    }

Go

deleteDatabaseInput := &timestreamwrite.DeleteDatabaseInput{
        DatabaseName:   aws.String(*databaseName),
    }

    _, err = writeSvc.DeleteDatabase(deleteDatabaseInput)

    if err != nil {
        fmt.Println("Error:")
        fmt.Println(err)
    } else {
        fmt.Println("Database deleted:", *databaseName)
    }

Python

    def delete_database(self):
        print("Deleting Database")
        try:
            result = self.client.delete_database(DatabaseName=Constant.DATABASE_NAME)
            print("Delete database status [%s]" % result['ResponseMetadata']['HTTPStatusCode'])
        except self.client.exceptions.ResourceNotFoundException:
            print("database [%s] doesn't exist" % Constant.DATABASE_NAME)
        except Exception as err:
            print("Delete database failed:", err)

Node.js

O trecho de código a seguir usa o SDK AWS para o JavaScript v3. Para obter mais informações sobre como instalar o cliente e o uso, consulte Timestream Write Client - AWS SDK para JavaScript v3.

Consulte também Class DeleteDatabaseCommand e 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; 
    } 
}

O trecho de código a seguir usa o SDK AWS para o estilo for JavaScript V2. Ele se baseia no aplicativo de amostra em Node.js, exemplo do aplicativo Amazon Timestream para LiveAnalytics no 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());
            }
        }
