How to read the runcontrol parameters in AE

We can read the Runcontrol Parameters in Application Engine by the following below 2 ways:


SQL
%select(EMPLID)selct EMPLID from PS_AERUNCONTROL where PROCESS_INSTANCE=%PROCESS_INSTANCE AND OPRID=%oprid


PeopleCode
&SQL="Select EMPLID from PS_AERUNCONTROL where PROCESS_INSTANCE="|PS_TEST_AET.PROCESS_INSTANCE|"and OPRID="|%oprid




%PROCESS_INSTANCE or %Bind(PROCESS_INSTANCE) can be used.
%PROCESS_INSTANCE is more efficent and faster
