Question

Hii
I have written query for fetting customer_name but i am getting wrong customer name .

This Query is for particular Org_id.
SELECT distinct HP.PARTY_NAME CUSTOMER_NAME
FROM HZ_PARTIES HP
,HZ_PARTY_SITES HPS
,HZ_CUST_SITE_USES_ALL HCS
,ORG_ORGANIZATION_DEFINITIONS OOD
WHERE HP.PARTY_ID=HPS.PARTY_ID
AND HPS.PARTY_SITE_ID=HCS.SITE_USE_ID
AND OOD.OPERATING_UNIT=HCS.ORG_ID
AND HCS.ORG_ID IN (87,88,89,90,91,92,93,94)

Answer 1

Basics of debugging.
Try to simplify the code and then add one variable at a time.
First select only from hz_parties.
Then add part_sites, then ood, then site_uses.
If you do that, you will find that you are joining hps.party_site_id with hsc.site_use_id.
Instead you need to join hps.party_site_id =hcs.cust_acct_site_id
You will also find that org_organization_definitions is making you use distinct. Anytime you have to use distinct to get rid of multiple rows when you were expecting one row, you can be sure that something is wrong in your query. The distinct is simply masking a problem.
Instead of ood, you need to use hr_operting_units.
The query becomes
select hp.party_name From hz_parties hp
,HZ_PARTY_SITES HPS
,HZ_CUST_SITE_USES_ALL HCS
,hr_operating_units hou
where hp.party_type='ORGANIZATION'
and HP.PARTY_ID=HPS.PARTY_ID
AND HPS.PARTY_SITE_ID=HCS.cust_acct_Site_id
AND HCS.ORG_ID IN (87,88,89,90,91,92,93,94)
AND hou.organization_id=HCS.ORG_ID
Hope this answers your question,
