Build Options is a great tool to enable or disable certain objects in APEX. If you've never used them before or don't know what they are I suggest you read Scott Wesley's article.
I typically use Build Options to display data for developers that should not be displayed in production. This can help improve development time since you don't have at include, then remove, code in an application before it is migrated to production.
Build Options are great for APEX but what about PL/SQL code that is directly associated with an APEX application? You could enable and disable certain page processes with build options but that doesn't allow "fine grained Build Option" control in your PL/SQL code.
Thankfully you can view your Build Options, and their status, with an APEX Dictionary view: APEX_APPLICATION_BUILD_OPTIONS.
Here is a function that I wrote that will allow you to easily see if a given Build Option is enabled in your PL/SQL code:
/** * Returns Y or N if a build option is enabled * * @param p_build_option_name Name of build option (case sensitive) * - You can change this to not be case sensitive if applicable * @param p_app_id Application ID, default current Application ID * - Included this as a parameter in case testing from straight PL/SQL * @return Y or N * @author Martin Giffy DSouza talkapex.com * @created 15-Aug-2012 */ create or replace FUNCTION f_is_build_option_enabled( p_build_option_name IN apex_application_build_options.build_option_name%TYPE, p_app_id IN apex_application_build_options.application_id%TYPE DEFAULT nv('APP_ID')) return varchar2 AS l_build_option_status apex_application_build_options.build_option_status%type; BEGIN SELECT upper(build_option_status) into l_build_option_status FROM apex_application_build_options WHERE application_id = p_app_id AND build_option_name = p_build_option_name; IF l_build_option_status = 'INCLUDE' THEN RETURN 'Y'; ELSE RETURN 'N'; END IF; exception WHEN others THEN -- Your call on how to handle errors raise; ENDHere's an example of how you can use it in your PL/SQL code. Note that it doesn't pass in the application id since it is assuming that you're executing the PL/SQL as part of the APEX application:
... IF f_is_build_option_enabled(p_build_option_name => 'DEV_ONLY') = 'Y' THEN htp.p('DEV_ONLY build option enabled'); ELSE htp.p('DEV_ONLY build option disabled'); END IF; ...
