Oracle Application Express API Reference describes the Application Programming Interfaces, referred to as APIs, available when programming in the Oracle Application Express environment.
Note:In Oracle Application Express 4.2, the APEX_DEBUG_MESSAGE package was renamed to APEX_DEBUG. The APEX_DEBUG_MESSAGE package name is still supported to provide backward compatibility. As a best practice, however, use the new APEX_DEBUG package for new applications unless you plan to run them in an earlier version of Oracle Application Express.
Note:In release 2.2, Oracle Application Express APIs were renamed using the prefix
APEX_. Note that API's using the previous prefix
HTMLDB_are still supported to provide backward compatibility. As a best practice, however, use the new API names for new applications unless you plan to run them in an earlier version of Oracle Application Express.
Oracle Application Express API Reference is intended for application developers who are building database-centric web applications using Oracle Application Express. The guide describes the APIs available when programming in the Oracle Application Express environment.
To use this guide, you need to have a general understanding of relational database concepts and an understanding of the operating system environment under which you are running Oracle Application Express.
