# DynamoDb code examples for the SDK for C++

## Overview

Sample code which demonstrates creation, deletion, modification, and querying of Amazon DynamoDB databases.

*Amazon 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.
* 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](https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#grant-least-privilege).
* This code is not tested in every AWS Region. For more information, see [AWS Regional Services](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services).

## Code examples

### Single actions

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

* [Create a table](./create_table.cpp) (CreateTable)
* [Create a table with composite key](./create_table_composite_key.cpp) (CreateTable)
* [Delete an item](./delete_item.cpp) (DeleteItem)
* [Delete a table](./delete_table.cpp) (DeleteTable)
* [Describe a table](./describe_table.cpp) (DescribeTable)
* [Get an item](./get_item.cpp) (GetItem)
* [Get items in a batch](./batch_get_item.cpp) (BatchGetItem)
* [List tables](./list_tables.cpp) (ListTables)
* [Put an item](./put_item.cpp) (PutItem)
* [Query items](./query_items.cpp) (Query)
* [Scan a table](./scan_table.cpp) (Scan)
* [Update an item](./update_item.cpp) (UpdateItem)
* [Update a table](./update_table.cpp) (UpdateTable)
* [Write a batch of items](./batch_write_item.cpp) (BatchWriteItem)

### Scenarios

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

* [Getting started scenario for DynamoDB](./dynamodb_getting_started_scenario.cpp) (CreateTable, PutItem, UpdateItem, BatchWriteItem, GetItem, Query, Scan, DeleteItem, DescribeTable, DeleteTable)
* [PartiQL single statement scenario for DynamoDB](./dynamodb_partiql_single_scenario.cpp) (CreateTable, ExecuteStatement, DescribeTable, DeleteTable)
* [PartiQL batch statements scenario for DynamoDB](./dynamodb_partiql_batch_scenario.cpp) (CreateTable, BatchExecuteStatement, DescribeTable, DeleteTable)
* 
## Run the examples

### Prerequisites

Before using the code examples, first complete the installation and setup steps
of [Getting started](https://docs.aws.amazon.com/sdk-for-cpp/v1/developer-guide/getting-started.html) 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](https://docs.aws.amazon.com/sdk-for-cpp/v1/developer-guide/getting-started-code-examples.html).

## Tests

⚠️ Running the tests might result in charges to your AWS account.

```sh
   cd <BUILD_DIR>
   cmake <path-to-root-of-this-source-code> -DBUILD_TESTS=ON
   make
   ctest 
 ```
