https://community.oracle.com/thread/3937159?start=0&tstart=0Sure, I can provide a detailed explanation of the answer options for this question.
The question asks about the fastest way to replace tabular forms with interactive grids in an old APEX application. Here are the four answer options:
A. Go to each page with a tabular form, copy the SQL Source from the Tabular Form region, and use it to create a new interactive grid.
This option would involve manually copying the SQL source from each tabular form region and then pasting it into a new interactive grid. While it may be a straightforward process, it could be time-consuming if there are many tabular forms to replace. Additionally, this approach would not automatically handle any other settings or configurations that were applied to the tabular forms, such as validations or dynamic actions.
B. Use the Create Page Wizard to create new pages with interactive grids, and then delete the old pages with tabular forms.
This option would involve using the Create Page Wizard to create new pages with interactive grids. The wizard can generate the SQL and other required components automatically, so it can save time compared to manually copying the SQL source. After creating the new pages, the old pages with tabular forms would need to be deleted. This approach can be faster than option A, but it still requires manual effort for deleting the old pages.
C. Use the Upgrade Application utility and select the candidate objects listed for "Upgrade Tabular Form to Interactive Grid", select all, and then click Upgrade.
This option involves using the Upgrade Application utility in APEX. This utility can automatically upgrade tabular forms to interactive grids, so it can save time compared to the previous two options. However, it may not work in all cases, depending on the specific customizations and configurations applied to the tabular forms. It is important to test the application thoroughly after using this utility to ensure that everything has been upgraded correctly.
D. Go to each report and change the type from Tabular Form to Interactive Grid.
This option would involve manually changing the type of each report from tabular form to interactive grid. Like option A, this approach could be time-consuming if there are many reports to update. Additionally, it would not automatically handle any other settings or configurations that were applied to the tabular forms.
Based on the explanations above, option C - using the Upgrade Application utility - appears to be the fastest and most efficient approach to replacing tabular forms with interactive grids in an old APEX application, especially if there are many tabular forms to upgrade. However, it is important to thoroughly test the application after using this utility to ensure that everything has been upgraded correctly.
