Querying tables in DynamoDB

You can use the Query API operation in Amazon DynamoDB to find items based on primary key values.

You must provide the name of the partition key attribute and a single value for that attribute. Query returns all items with that partition key value. Optionally, you can provide a sort key attribute and use a comparison operator to refine the search results.

For more information on how to use Query, such as the request syntax, response parameters, and additional examples, see Query in the Amazon DynamoDB API Reference.
