Unable to build SQL query for one parameter at multiple locations

Question

Hi,
Below one is the sample SQL in which I used :p_organization_id at 3 positions
First one at in the main where clause
Second one after START WITH
Third one is after CONNECT BY PRIOR
SELECT bs.assembly_item_id
,msia.segment1 a_item
,SYS_CONNECT_BY_PATH(msi.segment1, '---->') "Path",
bc.component_item_id,
bc.disable_date,
bc.item_num,
mp.organization_code organization_code,
LEVEL,
bc.attribute1 reference_no,
msi.segment1 item_number,
msi.description description
FROM inv.mtl_system_items_b msi,
inv.mtl_system_items_b msia,
bom.bom_structures_b bs,
bom.bom_components_b bc,
inv.mtl_parameters mp
WHERE
bc.component_item_id = msi.inventory_item_id
AND bc.bill_sequence_id = bs.bill_sequence_id
AND bs.assembly_item_id = msia.inventory_item_id
and msi.segment1 = 'P5200802-DB100'
AND bs.organization_id = msia.organization_id
AND msia.organization_id = msi.organization_id
AND msi.organization_id = mp.organization_id
AND mp.organization_code = :p_organization_id
AND NVL(TRUNC(bc.disable_date),TRUNC(SYSDATE + 1)) > TRUNC(SYSDATE)
START WITH msia.segment1 = '24310003-13.1' AND mp.organization_code = :p_organization_id
CONNECT BY PRIOR bc.component_item_id = bs.assembly_item_id
AND mp.organization_code = :p_organization_id
ORDER SIBLINGS BY bc.item_num
My question is how to use single parameter value that should go in the multiple positions in the SQL.
Please suggest if this can archived either in the Discoverer Admin / Desktop in detail.

Hi,
The only way you can use SQL with a connect by in Discoverer is to either put the SQL in a view or put the SQL in a custom folder. Either way you will not be able to pass parameter directly from Desktop/Plus to the view or custom folder.
The solution probably is to use session parameters and replace the :p_organization_id in the 3 positions with SYS_CONTEXT('DISCO_CONTEXT', 'ORGANIZATION_ID') once you have defined your DISCO_CONTEXT namespace and ORGANIZATION_ID session parameter.
See these threads for more information. (Re: Passing multiple parameters into Custom Folder... http://learndiscoverer.blogspot.com/2008/11/metalink-note-304192.html)
