通过阅读 Amazon DynamoDB 指南，我不明白是否有办法在查询/扫描后订购项目。

例如：

--我的数据库表--

        TableName:"Projects",
           Item:{
              "projectOwner": "User1",
              "projectName": "Project1",
              "creationDate": "Wed Nov 20 2016",
              "updateDate": "Wed Nov 29 2016",
         }Item:{
              "projectOwner": "User1",
              "projectName": "Project2",
              "creationDate": "Wed Nov 20 2016",
              "updateDate": "Wed Nov 28 2016",
         }Item:{
              "projectOwner": "User1",
              "projectName": "Project3",
              "creationDate": "Wed Nov 20 2016",
              "updateDate": "Wed Nov 30 2016",
         }

所以我想扫描我的数据库并返回按“updateDate”排序的所有项目。有没有办法使用 dynamoDB 参数来实现这一点？

        params = {
             TableName: "Projects",
             ProjectionExpression: "projectName",
             KeyConditionExpression: "projectOwner = :userId",
             ExpressionAttributeValues: {
                 ":userId":userId
             }
        };
