PL/SQL Interactive Report issues - Piped function or Collections

Question

Hi,
I have a report where I either want to limit the return by date or return all. PL/SQL didn't work in the Interactive Report (is it available in 3.2?) then my second idea (2 reports; one for each option) didn't work as you can't have more than one IR on a page. Searching here I found people guiding others to here for collections and here for piped functions.
Ok I finally understood the collections thing (didn't realise that "function_returning_query" would be replaced with your code) but I'm not sure it can be used in my situation? I want it to be dependent upon a LOV on the page with my predicted code like:DECLARE
q VARCHAR2(30000);
BEGIN
q := 'select UPD_ID, PROJECT,DATABASE,REF,DESCRIP,STATUS,PERSON,
TO_CHAR(INS_DATE, ''HH24:MI DD-MON-YY'') AS INS_DATE
from TBL_ENV_LOG';
IF :P5_DAYS != 1337 THEN
q := q || ' where TBL_ENV_LOG.INS_DATE >= TO_TIMESTAMP(SYSDATE - :P5_DAYS)';
END IF;
q := q || ' order by TBL_ENV_LOG.INS_DATE desc';
return(q);
END;So the value of :P5_DAYS would need to go there somehow, can it be passed as a parameter?
Is there another way to do this? Making lots of hidden fields is annoying :/
Edit: I used a CASE statement for a column before, could I use that for entire queries?

Answer 1

Hi,
CREATE OR REPLACE FUNCTION BLOG_FUNC RETURN VARCHAR2 IS
q VARCHAR2(30000);
BEGIN
q := 'select UPD_ID, PROJECT,DATABASE,REF,DESCRIP,STATUS,PERSON,
TO_CHAR(INS_DATE, ''HH24:MI DD-MON-YY'') AS INS_DATE
from TBL_ENV_LOG';
IF :P5_DAYS != 1337 THEN
q := q || ' where TBL_ENV_LOG.INS_DATE >= TO_TIMESTAMP(SYSDATE -' || :P5_RAD|| ')';
END IF;
q := q || ' order by TBL_ENV_LOG.INS_DATE desc';
return(q);
END;Error at line 8: PLS-00049: bad bind variable 'P5_RAD'
I assume I need to pass parameter values like P5_RAD but how do I relate it to:Select *
From apex_collections
Where collection_name = ‘IR_TEST’;
is it...
Select *
From apex_collections(:P5_RAD)
Where collection_name = ‘IR_TEST’;
??Edit: The IR query changes to BLOG_FUNC(:P5_RAD) right?
Edit 2: Nope that doesn't work :/
