The APEX_EXEC package encapsulates data processing and querying capabilities and provides an abstraction from the data source to APEX components and plug-ins. APEX_EXEC contains procedures and functions to execute queries or procedural calls on local and remote data sources as well as REST Data Sources. It can be used for plug-in development and procedural PL/SQL processing in applications or within packages and procedures.

All APEX_EXEC procedures require an existing APEX session to function. In a pure SQL or PL/SQL context, use the APEX_SESSION package to initialize a new session.
