DynamoDB code examples for the SDK for C++

Overview

Shows how to use the AWS SDK for C++ to work with Amazon DynamoDB.

DynamoDB is a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability.

⚠ Important

Running this code might result in charges to your AWS account. For more details, see AWS Pricing and Free Tier.
Running the tests might result in charges to your AWS account.
We recommend that you grant your code least privilege. At most, grant only the minimum permissions required to perform the task. For more information, see Grant least privilege.
This code is not tested in every AWS Region. For more information, see AWS Regional Services.

Code examples

Prerequisites

Before using the code examples, first complete the installation and setup steps for Getting started in the AWS SDK for C++ Developer Guide. This section covers how to get and build the SDK, and how to build your own code by using the SDK with a sample Hello World-style application.

Next, for information on code example structures and how to build and run the examples, see Getting started with the AWS SDK for C++ code examples.

Get started

Hello DynamoDB (ListTables)

Basics

Code examples that show you how to perform the essential operations within a service.

Learn the basics

Single actions

Code excerpts that show you how to call individual service functions.

Scenarios

Code examples that show you how to accomplish a specific task by calling multiple functions within the same service.

Run the examples

Instructions

An executable is built for each source file in this folder. These executables are located in the build folder and have "run_" prepended to the source file name, minus the suffix. See the "main" function in the source file for further instructions.

For example, to run the action in the source file "my_action.cpp", execute the following command from within the build folder. The command will display any required arguments.

./run_my_action

If the source file is in a different folder, instructions can be found in the README in that folder.

Hello DynamoDB

This example shows you how to get started using DynamoDB.

Learn the basics

This example shows you how to do the following:

Create a table that can hold movie data.
Put, get, and update a single movie in the table.
Write movie data to the table from a sample JSON file.
Query for movies that were released in a given year.
Scan for movies that were released in a range of years.
Delete a movie from the table, then delete the table.

Create a serverless application to manage photos

This example shows you how to create a serverless application that lets users manage photos using labels.

Query a table by using batches of PartiQL statements

This example shows you how to do the following:

Get a batch of items by running multiple SELECT statements.
Add a batch of items by running multiple INSERT statements.
Update a batch of items by running multiple UPDATE statements.
Delete a batch of items by running multiple DELETE statements.

Query a table using PartiQL
