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](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/clients/client-timestream-write/index.html).

```
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);

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](https://github.com/awslabs/amazon-timestream-tools/tree/mainline/sample_apps/js) 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  ]
