SQL将最新进度更新链接到交互式报告中的项目记录Oracle APEX

我正在为我的团队创建一个项目数据库。每个项目都位于一个名为project的表中，我有一个名为PROGRESSUPDATES的单独表来跟踪用户添加到其项目中的任何进度

我想在交互式报告中显示每个项目的最新更新

数据样本如下：

项目：

id | NAME             | Description | Status
______________________
1  | Project 1        | abc         | On Track
2  | Project 2        | def         | On Hold
3  | Project 3        | ghi         | Completed
4  | Project 4        | jkl         | Cancelled
5  | Project 5        | mno         | On Track

进度更新：

id | NAME             | Update             | Date
______________________
1  | Project 1        | Update 1 of 3      | 04-APR-16 11.29.00.000000 AM
1  | Project 1        | Update 2 of 3      | 05-APR-16 11.29.00.000000 AM
1  | Project 1        | Update 3 of 3      | 10-APR-16 11.29.00.000000 AM
4  | Project 4        | Update for P4      | 29-MAR-16 01.30.00.000000 PM
4  | Project 4        | New Update for P4  | 05-APR-16 01.30.00.000000 PM
5  | Project 5        | Update for P5      | 05-APR-16 11.47.00.000000 AM

预期结果：

一些同事在工作中设法解决了这个问题，并希望共享代码，以防它对其他人有帮助
