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.

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

This example shows you how to do the following:

• Get an item by running a SELECT statement.
• Add an item by running an INSERT statement.
• Update an item by running an UPDATE statement.
• Delete an item by running a DELETE statement.
