Retrieve SQL with filters applied from an Interactive Report

Question

I want to use an Interactive report as interface for providing parameters to a base report query.
I would like to capture the full SQL code from the filtered interactive report and then run the sql to create a collection.
I have found this tread
Re: Using Data from filtered Interactive Report
which says that you can use APEX_APPLICATION_PAGE_IR to access the reports SQL. This holds the information about the interactive report when the user saves it. The sql code from the interactive report (after the user has added filters) is stored in the field sql_query.I can only retrieve the base query and not the filtered version even after saving.
Any ideas how this can be done would be appreciated.

OK Darren I think I've got it working. My solution is an adaption that follows the steps of a blog I found here: http://stewstools.wordpress.com/2009/02/19/get-ir-where-clause/
My solution allows you to click on a button and the records that are currently displayed in the IR report are saved to an APEX collection. You can then use the collection to save records to a table or run a report on another page. (I haven't included code for this last step but it's easy to find on the forum)
First a bit of background knowledge. The following APEX views hold all the information on IRs that you access via PLSQL code in the package you need to download. Run an IR report, save a version of the report, then in SQL Workshop have a look at:
select * from APEX_APPLICATION_PAGE_IR
select * from APEX_APPLICATION_PAGE_IR_COND
select * from APEX_APPLICATION_PAGE_IR_COL
select * from APEX_APPLICATION_PAGE_IR_RPT
When you run an IR report it has an internal ID that you can access and also a Base Id for each Saved report that is currently in context.
Here are the steps:
1) Download the following package and install it in the workspace schema
http://www.mediafire.com/?nj118x9vmc9
click on the link "click here to download"
2)In the HTML header Attribute of the page where your IR runs, put the following Javascript:
<!--===================================================================-->
<!--FUNCTION TO RETRIEVE IR REPORTS SQL WITH WHERE CLAUSE
<!--===================================================================-->
<script language="JavaScript" type="text/javascript">
function SaveAndRunReport() {
document.location='f?p=&APP_ID.:3:&SESSION.:CONSTRUCT_IR_QUERY:NO::'+
'P3_BASE_REPORT_ID:'+$v('apexir_REPORT_ID');
</script>
<!--===================================================================-->
Notes: You will need to obviously change the URL above to reflect your Page No. (3) and the name of a HIDDEN Item (P3_BASE_REPORT_ID) that you will populate with the base ID of the report.
Setting :P3_BASE_REPORT_ID to +$v('apexir_REPORT_ID') is an internal thing and works out of the box. It returns the Id of the Base report.
3) Create a button called SELECT_SPECIMENS (in region position - top of region) in the IR region that will initiate the execution of the IR background SQL to create a collection with the current selected records.
TARGET= URL
URL Target = javascript:SaveAndRunReport();
You might also want to create a condition that only shows the button when there are records selected
CONDITION TYPE=Exists(SQL returns at least one row)
EXPRESSION 1 - put the SQL of the IR report here.
4)Create a branch back to the same page (3) and with the REQUEST attribute set to the value in the Javascript URL above e.g. CONSTRUCT_IR_QUERY. Create a condition on the branch that uses this branch WHEN BUTTON PRESSED= SELECT_SPECIMENS
5) Create an AFTER HEADER PROCESS with the following code:
declare
v_base_query clob;
v_where clob;
v_query clob;
v_base_where varchar2(12):=' where 1=1 '; -- incase there is no where clause in the base query
begin
if apex_collection.collection_exists('IR_COLLECTION') THEN
htmldb_collection.delete_collection( p_collection_name => 'IR_COLLECTION');
end if;
--GET THE BASE QUERY OF THE IR REPORT
select sql_query
into v_base_query
from APEX_APPLICATION_PAGE_IR
where application_id=:APP_ID
and page_id=:APP_PAGE_ID; -- you can only have one IR report per page
--UNCOMMENT TO VIEW THE PARAMETERS TO THE PACKAGED FUNCTION
--raise_application_error(-20001, :APP_ID||'-'||:APP_PAGE_ID||'-'||:SESSION||'-'||:P3_BASE_REPORT_ID);
--GET THE SQL FILTER CODE
select apex_ir_query.ir_query_where(:APP_ID,:APP_PAGE_ID,:SESSION,:P3_BASE_REPORT_ID)
into v_where
from dual;
--CHECK TO SEE THAT THERE IS A "WHERE" CLAUSE IN THE BASE QUERY
if instr(upper(v_base_query),'WHERE ') > 0 then
v_query:=v_base_query||' '||v_where;
else
v_query:=v_base_query||' '||v_base_where||' '||v_where;
end if;
--UNCOMMENT TO SEE THE FULL QUERY SYNTAX
--raise_application_error(-20001,v_query);
--CREATE COLLECTION FROM IR RECORDS
apex_collection.create_collection_from_query(P_collection_name=>'IR_COLLECTION',p_query=>v_query);
exception
when others then
raise_application_error(-20001, 'Interactive report not found. Contact Administrator. Could not create collection of records.');
end;
remember to update P3_BASE_REPORT_ID above to your HIDDEN ITEM name.
Set the following attributes for the process above
CONDITIONAL PROCESSING
CONDITION TYPE = Request=Expression 1
EXPRESSION 1 --> CONSTRUCT_IR_QUERY (Note: this was set on the branch in step 4 above)
6) Run the IR report, click on the "SELECT SPECIMENS" button then click on the Session link on the Developer's Toolbar and select VIEW COLLECTIONS from the popup list then click GO. You should now see the IR records.
By the way I've been testing in IE not Firefox.
...and that's it!
enjoy
