**To scan a table** This example scans the entire *MusicCollection* table, and then narrows the results to songs by the artist "No One You Know". For each item, only the album title and song title are returned. Command:: aws dynamodb scan --table-name MusicCollection --filter-expression "Artist = :a" --projection-expression "#ST, #AT" --expression-attribute-names file://expression-attribute-names.json --expression-attribute-values file://expression-attribute-values.json The arguments for ``--expression-attribute-names`` are stored in a JSON file, ``expression-attribute-names.json``. Here are the contents of that file:: { "#ST": "SongTitle", "#AT":"AlbumTitle" } The arguments for ``--expression-attribute-values`` are stored in a JSON file, ``expression-attribute-values.json``. Here are the contents of that file:: { ":a": {"S": "No One You Know"} } Output:: { "Count": 2, "Items": [ { "SongTitle": { "S": "Call Me Today" }, "AlbumTitle": { "S": "Somewhat Famous" } }, { "SongTitle": { "S": "Scared of My Shadow" }, "AlbumTitle": { "S": "Blue Sky Blues" } } ], "ScannedCount": 3, "ConsumedCapacity": null }
