# Descrever tabela
<a name="code-samples.describe-table"></a>

Use os seguintes trechos de código para obter informações sobre os atributos da tabela.

**nota**  
Esses trechos de código são baseados em aplicativos de amostra completos no [GitHub](https://github.com/awslabs/amazon-timestream-tools/blob/master/sample_apps). Para obter mais informações sobre como criar aplicativos de amostra, consulte [Aplicação de exemplo](sample-apps.md).

O trecho de código a seguir usa o SDK AWS para o estilo for JavaScript V2. Ele se baseia no aplicativo de amostra no [aplicativo de amostra Node.js do Amazon Timestream para LiveAnalytics no GitHub](https://github.com/awslabs/amazon-timestream-tools/tree/mainline/sample_apps/js).

        TableName: constants.TABLE_NAME

    const promise = writeClient.describeTable(params).promise();

    await promise.then(
        (data) => {
