You must reference certain data from a dragged event under the Drag and Drop PL/SQL Code attribute of the Calendar component.

Examine this list:
1. ID
2. NEW_START_DATE
3. NEW_END_DATE

How can these be referenced?

A. #APEX$PK_VALUE#, #APEX$NEW_START_DATE#, and #APEX$NEW_END_DATE#
B. :APEX$PK_VALUE, APEX$NEW_START_DATE, and :APEX$NEW_END_DATE
C. :APEX.PK_VALUE, :APEX.NEW_START_DATE, and :APEX.NEW_END_DATE
D. #APEX.PK_VALUE#, #APEX.NEW_START_DATE#, and #APEX.NEW_END_DATE#

Answer :

In Oracle Application Express (APEX), when dealing with events in a calendar component, there is a specific way to reference certain attributes, especially during a drag and drop action. When a dragged event needs to reference attributes such as ID, NEW_START_DATE, or NEW_END_DATE under the PL/SQL Code attribute of the Calendar component, the following notations are used:

  1. ID is referenced using :APEX$PK_VALUE. This references the primary key of the calendar event.

  2. NEW_START_DATE is referenced using :APEX$NEW_START_DATE. This represents the new start date after the event has been dragged to a new position on the calendar.

  3. NEW_END_DATE is referenced using :APEX$NEW_END_DATE. This signifies the new end date after moving the event.

These special bind variables, prefixed with :APEX$, are used to reference specific values within event handling in APEX applications. This notation ensures that the application can dynamically handle the values as they shift during user interactions.

The correct choice from the options provided corresponds to:

":APEX[tex]PK_VALUE, :APEX[/tex]NEW_START_DATE, and :APEX$NEW_END_DATE".
