Error when create new apex_collection

Question

Hi everyone,
I try to create a process as below
apex_collection.create_collection_from_query(
p_collection_name => base_collection,
p_query => "SELECT ASAT_DATE, ADMINISTRATION_UNIT_ID, PROJECT_ID, SUM(TOTAL_BOOKED_HOURS) as TOTAL_BOOKED_HOURS FROM CAREARR_TOTALS_SUBS2 WHERE ASAT_DATE IN ('30/01/12', '06/02/12', '13/02/12', '20/02/12', '27/02/12', '05/03/12', '12/03/12', '19/03/12') AND ADMINISTRATION_UNIT_ID = :P82_ADMIN_UNIT GROUP BY ASAT_DATE, ADMINISTRATION_UNIT_ID, PROJECT_ID");
and get error
ORA-06550: line 5, column 14: PLS-00114: identifier 'SELECT ASAT_DATE, ADMINISTRATI' too long
The reason is the limitation of the version of Oracle that my organization run . They run Oracle 10g, the version of APEX is 3.0.1
Managers want the report is displayed so that the dates would be columns not row.
I find that I can use the PIVOT in Oracle 11g but not in 10g.
I did try to write function, and make the select
SELECT distinct get_total_booked_hours(asat_date, project_id) as "WEEK 1"
, get_total_booked_hours(asat_date + 7, project_id) as "WEEK 2"
, get_total_booked_hours(asat_date + 14, project_id) as "WEEK 3"
, get_total_booked_hours(asat_date + 21, project_id) as "WEEK 4"
, get_total_booked_hours(asat_date + 28, project_id) as "WEEK 5"
FROM CAREARR_TOTALS_SUBS2
WHERE ADMINISTRATION_UNIT_ID = :P82_ADMIN_UNIT AND ASAT_DATE ='20/02/12'
But the query took way too long. (kind of 5 times as the first one).
Now I try to use apex_collection to store the results of the query that can run faster, then display the report base on hat apex_collection.
But I get stuck as above.
If anyone has any ideas, please give me some hints.
Thanks a lot in advance.

I am not quite sure I get what you mean, so I adjust the above code to
DECLARE
base_collection VARCHAR2(32767) := '';
v_query VARCHAR2(2000);
BEGIN
apex_collection.create_collection_from_query(
p_collection_name => base_collection,
p_query => q'!
SELECT ASAT_DATE,
ADMINISTRATION_UNIT_ID,
PROJECT_ID,
SUM(TOTAL_BOOKED_HOURS) AS TOTAL_BOOKED_HOURS
FROM CAREARR_TOTALS_SUBS2
WHERE ASAT_DATE IN (:P82_STARTDATE
,TO_DATE(:P82_STARTDATE, 'DD/MM/YY') + 7
,TO_DATE(:P82_STARTDATE, 'DD/MM/YY') + 14
,TO_DATE(:P82_STARTDATE, 'DD/MM/YY') + 21)
AND ADMINISTRATION_UNIT_ID = !'
|| :P82_ADMIN_UNIT || '
GROUP BY ASAT_DATE,
ADMINISTRATION_UNIT_ID,
PROJECT_ID'
END;
I still have the same error: I turn on debug, and here is the result.

Should I create a hidde item to store the APEX COLLECTION ?
Is it possible ?
Many thanks
