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

You can use the following code snippets to get information about the attributes of your table.

**Note**  
These code snippets are based on full sample applications on [GitHub](https://github.com/awslabs/amazon-timestream-tools/blob/master/sample_apps). For more information about how to get started with the sample applications, see [Sample application](sample-apps.md).

------
#### [  Java  ]

```
    public void describeTable() {
        System.out.println("Describing table");
        final DescribeTableRequest describeTableRequest = new DescribeTableRequest();
        describeTableRequest.setDatabaseName(DATABASE_NAME);
        describeTableRequest.setTableName(TABLE_NAME);
        try {
            DescribeTableResult result = amazonTimestreamWrite.describeTable(describeTableRequest);
            String tableId = result.getTable().getArn();
            System.out.println("Table " + TABLE_NAME + " has id " + tableId);
        } catch (final Exception e) {
            System.out.println("Table " + TABLE_NAME + " doesn't exist = " + e);
            throw e;
        }
    }
```

------
#### [  Java v2  ]

```
    public void describeTable() {
        System.out.println("Describing table");
        final DescribeTableRequest describeTableRequest = DescribeTableRequest.builder()
                .databaseName(DATABASE_NAME).tableName(TABLE_NAME).build();
        try {
            DescribeTableResponse response = timestreamWriteClient.describeTable(describeTableRequest);
            String tableId = response.table().arn();
            System.out.println("Table " + TABLE_NAME + " has id " + tableId);
        } catch (final Exception e) {
            System.out.println("Table " + TABLE_NAME + " doesn't exist = " + e);
            throw e;
        }
    }
```

------
#### [  Go  ]

```
// Describe table.
    describeTableInput := &timestreamwrite.DescribeTableInput{
        DatabaseName: aws.String(*databaseName),
        TableName:    aws.String(*tableName),
    }
    describeTableOutput, err := writeSvc.DescribeTable(describeTableInput)

    if err != nil {
        fmt.Println("Error:")
        fmt.Println(err)
    } else {
        fmt.Println("Describe table is successful, below is the output:")
        fmt.Println(describeTableOutput)
    }
```

------
#### [  Python  ]

```
    def describe_table(self):
        print("Describing table")
        try:
            result = self.client.describe_table(DatabaseName=Constant.DATABASE_NAME, TableName=Constant.TABLE_NAME)
            print("Table [%s] has id [%s]" % (Constant.TABLE_NAME, result['Table']['Arn']))
        except self.client.exceptions.ResourceNotFoundException:
            print("Table doesn't exist")
        except Exception as err:
            print("Describe table failed:", err)

The following snippet uses AWS SDK for JavaScript v3. For more information about how to install the client and usage, see [Timestream Write Client - AWS SDK for JavaScript v3](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/clients/client-timestream-write/index.html).

Also see [Class DescribeTableCommand](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/clients/client-timestream-write/classes/describedatabasecommand.html) and [DescribeTable](https://docs.aws.amazon.com/timestream/latest/developerguide/API_DescribeTable.html).

```
import { TimestreamWriteClient, DescribeTableCommand } from "@aws-sdk/client-timestream-write";
const writeClient = new TimestreamWriteClient({ region: "us-east-1" });

const params = {
    DatabaseName: "testDbFromNode",
    TableName: "testTableFromNode"
};

const command = new DescribeTableCommand(params);

try {
    const data = await writeClient.send(command);
    console.log(`Table ${data.Table.TableName} has id ${data.Table.Arn}`);
} catch (error) {
    if (error.code === 'ResourceNotFoundException') {
        console.log("Table or Database doesn't exist.");
    } else {
        console.log("Describe table failed.", error);
        throw error;
    }
}
```

The following snippet uses the AWS SDK for JavaScript V2 style. It is based on the sample application at [Node.js sample Amazon Timestream for LiveAnalytics application on GitHub](https://github.com/awslabs/amazon-timestream-tools/tree/mainline/sample_apps/js).

```
async function describeTable() {
    console.log("Describing Table");
    const params = {
        DatabaseName: constants.DATABASE_NAME,
        TableName: constants.TABLE_NAME
    };

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

    await promise.then(
        (data) => {
            console.log(`Table ${data.Table.TableName} has id ${data.Table.Arn}`);
        },
        (err) => {
            if (err.code === 'ResourceNotFoundException') {
                console.log("Table or Database doesn't exists.");
            } else {
                console.log("Describe table failed.", err);
                throw err;
            }
        }
    );
}
```

#### [  .NET  ]

```
        public async Task DescribeTable()
        {
            Console.WriteLine("Describing Table");

            try
            {
                var describeTableRequest = new DescribeTableRequest
                {
                    DatabaseName = Constants.DATABASE_NAME,
                    TableName = Constants.TABLE_NAME
                };
                DescribeTableResponse response = await writeClient.DescribeTableAsync(describeTableRequest);
                Console.WriteLine($"Table {Constants.TABLE_NAME} has id:{response.Table.Arn}");
            }
            catch (ResourceNotFoundException)
            {
                Console.WriteLine("Table does not exist.");
            }
