Conditionally Setting Bind Variables

Question

I need help conditionally setting some bind variables so I don't have to hard code some values. However, I get errors when I try to do this. I might just be going about it the wrong way. This is my code so far:
DECLARE
       first_offset varchar2(3);
       second_offset varchar2(3);
       current_term  varchar2(6);
BEGIN
  current_term := (SELECT robinst_current_term_code
  FROM robinst
  WHERE robinst_aidy_code = :aidy)
  CASE
  WHEN current_term LIKE '%60' THEN first_offset := '40'
  AND second_offset := '100'
  WHEN current_term LIKE '%20' THEN first_offset := '100'
  AND second_offset := '160'
  END
END;
/I want to then use the offest variables in a select query afterwords. Is this possible, or what do I appear to be doing wrong?

Answer 1

This works when I run it in toad:
VARIABLE first_offset varchar2(3)
VARIABLE second_offset varchar2(3)
VARIABLE current_term  varchar2(6)
BEGIN
  SELECT robinst_current_term_code
  INTO current_term
  FROM robinst
  WHERE robinst_aidy_code = :AIDY;
first_offset := CASE 
  WHEN current_term LIKE '%60' THEN '40'
  WHEN  current_term LIKE '%20' THEN '100'
  END;
  second_offset := CASE
  WHEN current_term LIKE '%60' THEN '100'
  WHEN current_term LIKE '%20' THEN '160'
  END;
END;
SELECT spriden_id id, spriden_last_name||', '||spriden_first_name name
FROM spriden
WHERE spriden_pidm IN(

FROM RCRESAR A,RCRAPP1,SGBSTDN,SORLCUR, RCRAPP2, ROBINST

ORDER BY nameBut it prompts me for my bind variables: current_term, first_offset, and second_offset. If I don't type in values I get no rows returned. When I type in what should be getting set in my pl/sql block it works fine. What could be the problem now? The purpose of the variables is to not to have to type anything.
