A dynamic List of Values (LOV) in APEX populates options based on a query source. The supported
types include:
Function Returning SQL Query: A PL/SQL function that returns a SQL query string (e.g., RETURN
'SELECT ename, empno FROM emp';). This offers flexibility for dynamic conditions or complex logic.
SQL Query: A direct SQL statement (e.g., SELECT ename, empno FROM emp) executed at runtime to
fetch LOV values. It’s the simplest and most common approach.
Procedure: Procedures execute logic but don’t return query results in the format required for an LOV
(they don’t produce a result set directly).
Select List: This is a UI component, not a query source type for defining an LOV.
Dynamic LOVs enhance user interaction by providing real-time, data-driven options, critical for forms
and filters.
