我在这个查询上并不太成功,它返回了0个项目。
我希望 2018-02-20T02:58:49.710Z 落在 2017-08-30T03:11:22.627Z 和现在之间。您能帮忙查询吗?
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();
我在数据库中有一个项目:
{
"id": "fa47003a-983a-4dc3-a87e-ace73ea7e451",
"createdDateTime": "2018-02-20T02:58:49.710Z",
"status": "SUCCESS"
}
表格:
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}"
