title: Oracle APEX_COLLECTIONS equivalent in Oracle PL/SQL alone
body: <p>I am using Oracle 11g R2.</p>
  
  <p>I'm purely working in the backend alone using PL/SQL where I need to re-write all PL/SQL code that was used within Oracle APEX v4.2 that uses/calls  APEX_COLLECTIONS. </p>
  
  <p>Since I am not able to re-use the APEX_COLLECTION API within PL/SQL without Oracle APEX, can people please advise what the equivalent of APEX_COLLECTIONS is within vanilla PL/SQL?</p>
  
  <p>I will potentially need a maximum of 50 character columns.</p>
  
  <p>I was thinking of global temporary tables but unsure how this would work.</p>
