An application includes a form on the EMPLOYEES table. You must limit the P1_MANAGER page item so users can select a single employee name and ID from the corresponding manager ID in the same table. Which item type can be used to display P1_MANAGER?
Correct Answer: A
The requirement is to allow users to pick a single employee (name and ID) from a list tied to the MANAGER_ID column in the EMPLOYEES table, implying a dynamic, searchable selection: A . Popup LOV: This item type displays a popup window with a searchable list of values, sourced from a SQL query (e.g., SELECT ename, empno FROM employees WHERE empno IN (SELECT DISTINCT manager_id FROM employees)). It returns a single value (e.g., EMPNO) while displaying the name, perfectly meeting the need for a single selection from a related dataset. B . Switch: A toggle (Yes/No), unsuitable for selecting from a list of employees. C . Checkbox: Allows multiple selections, conflicting with the "single employee" requirement. Practical note: Popup LOVs enhance usability with filtering and pagination, ideal for large employee lists, and support returning the ID while showing the name.
