DynamoDb: Query items between two dates

ChrisRich picture ChrisRich · Aug 30, 2018 · Viewed 8.6k times · Source

I'm not having much luck with this query, it returns 0 items

const { Items } = await this.dynamoDb.query({
  TableName: 'exampleTableName',
  IndexName: 'createdDateTime-index',
  KeyConditionExpression: '#createdDateTime BETWEEN :fromDateTime AND :toDateTime AND #status = :status',
  ExpressionAttributeNames: {
    '#status': 'status',
    '#createdDateTime': 'createdDateTime',
  },
  ExpressionAttributeValues: {
    ':fromDateTime': '2017-02-20T01:58:49.710Z',
    ':toDateTime': new Date().toISOString(),
    ':status': 'SUCCESS',
  },
}).promise();

I have one item in the DB:

{
  "id": "fa47003a-983a-4dc3-a87e-ace73ea7e451",
  "createdDateTime": "2018-02-20T02:58:49.710Z",
  "status": "SUCCESS"
}

Table:

aws dynamodb create-table \
  --endpoint-url http://localhost:8000 \
  --table-name exampleTableName \
  --attribute-definitions \
    AttributeName=id,AttributeType=S \
    AttributeName=status,AttributeType=S \
    AttributeName=createdDateTime,AttributeType=S \
  --key-schema \
    AttributeName=id,KeyType=HASH \
  --provisioned-throughput ReadCapacityUnits=10,WriteCapacityUnits=10 \
  --global-secondary-indexes \
    IndexName=createdDateTime-index,KeySchema=["{AttributeName=status,KeyType=HASH},{AttributeName=createdDateTime,KeyType=RANGE}"],Projection="{ProjectionType=ALL}",ProvisionedThroughput="{ReadCapacityUnits=10,WriteCapacityUnits=10}"

I would expect 2018-02-20T02:58:49.710Z to fall between 2017-08-30T03:11:22.627Z and now.

Can you help out with the query?

As @cementblocks mentioned, the query works as expected.
