テーブルを削除する

次のコードスニペットを使用してテーブルを削除できます。

注記

これらのコードスニペットは、 上の完全なサンプルアプリケーションに基づいていますGitHub。サンプルアプリケーションの開始方法の詳細については、「」を参照してくださいサンプルアプリケーション。

Java 
    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 := &timestreamwrite.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)
Node.js

次のスニペットは JavaScript v3 に を使用します AWS SDK。クライアントのインストール方法と使用状況の詳細については、 JavaScript 「v3 SDKの Timestream Write Client - AWS」を参照してください。

クラス DeleteTableCommand と も参照してください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; 
    } 
}

次のスニペットは JavaScript V2 スタイルに AWS SDKを使用します。これは、Node.js のサンプルアプリケーションに基づいており、 の LiveAnalytics アプリケーション用の Amazon Timestream サンプルです 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());
            }
