Command:: aws dynamodb query --table-name MusicCollection --projection-expression "SongTitle" --key-condition-expression "Artist = :v1" --expression-attribute-values file://expression-attributes.json The arguments for ``--expression-attribute-values`` are stored in a JSON file named ``expression-attributes.json``:: { ":v1": {"S": "No One You Know"} } Output:: { "Count": 2, "Items": [ { "SongTitle": { "S": "Call Me Today" }, "SongTitle": { "S": "Scared of My Shadow" } } ], "ScannedCount": 2, "ConsumedCapacity": null }
