**To scan a table**
The following ``scan`` 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. ::
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
Contents of ``expression-attribute-names.json``::
{
"#ST": "SongTitle",
"#AT":"AlbumTitle"
}
Contents of ``expression-attribute-values.json``::
{
":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
}
