Help With Dynamic PL/SQL LOV Syntax

Question

Hello
I am trying to create a dynamic pl/sql lov in Oracle Apex 3.2 on 11g. I am having some issues with the syntax of the statements below and I'd appreciate any suggestions.
DECLARE
BEGIN
IF :p3_current_a_workshop != 0 THEN
RETURN
'select distinct workshop_title ||':  '  || presenter_name ||'    $'|| workshop_fee display_value, workshop_id return_value
from WORKSHOP
where session_time = 'A'
and workshop_status = 'Open'
or workshop_id = :p3_current_a_workshop
order by 1';
ELSE
RETURN
'select distinct workshop_title ||':  '  || presenter_name ||'    $'|| workshop_fee display_value, workshop_id return_value
from WORKSHOP
where session_time = 'A'
and workshop_status = 'Open'
order by 1';
END IF;
EXCEPTION
        WHEN OTHERS THEN
            HTP.PRN('ERROR'||SQLERRM);         
END;I am trying to model the above code off of the example given by apex:
A function that returns a SQL query with two columns:
IF :MY_ITEM='10' THEN
  RETURN
  'SELECT ename, empno
FROM  emp
WHERE depno = 10
ORDER BY 1';
ELSE
  RETURN
  'SELECT ename, empno
FROM emp
WHERE depno = :my_item
ORDER BY 1';
END IF;~Andrew Schultz

Hi Andrew,
Try something like:
DECLARE
BEGIN
IF :p3_current_a_workshop != 0 THEN
RETURN
' select distinct workshop_title ||'':  ''  || presenter_name ||''    $''|| workshop_fee display_value, workshop_id return_value '||
' from WORKSHOP '||
' where session_time = ''A'' '||
' and workshop_status = ''Open'' '||
' or workshop_id = :p3_current_a_workshop '||
' order by 1 ';
ELSE
RETURN
' select distinct workshop_title ||'':  ''  || presenter_name ||''    $''|| workshop_fee display_value, workshop_id return_value '||
' from WORKSHOP '||
' where session_time = ''A'' '||
' and workshop_status = ''Open'' '||
' order by 1 ';
END IF;
EXCEPTION
        WHEN OTHERS THEN
            HTP.PRN('ERROR'||SQLERRM);         
END;Regards,
