Finding Changed PeopleCode

When promoting a project to our Test or QA environment from development, often we are missing changes that we intended to put into our PeopleSoft Project definition.  Whenever I have a project that takes me multiple weeks to complete I like to run this SQL to evaluate what PeopleCode events have been changed that don't exist in my project.

Bind :1 = OPRID that made the code changes.
Bind :2 = Project Name that is being promoted.

SELECT * FROMPSPCMPROG A 
WHERE LASTUPDOPRID = ':1' AND LASTUPDDTTM > (sysdate - 19)
AND NOT EXISTS ( SELECT 'X' FROM PSPROJECTITEM X WHERE X.PROJECTNAME = ':2'
                  AND X.OBJECTID1 = A.OBJECTID1
                  AND X.OBJECTVALUE1 = A.OBJECTVALUE1
                  AND X.OBJECTID2 = A.OBJECTID2
                  AND X.OBJECTVALUE2 = A.OBJECTVALUE2
                  AND X.OBJECTID3 = A.OBJECTID3
                  AND X.OBJECTVALUE3 = A.OBJECTVALUE3
                  AND X.OBJECTID4 = A.OBJECTID4
                  AND X.OBJECTVALUE4 = A.OBJECTVALUE4);
