Need join to get the SR contact

Question

I need to know how to get the contact name for a service request. This is what I have so far given that I know the service request number and the contact name (from looking at the forms)
select * from cs_incidents_all_b where incident_id = 10333
--customer_id = 1284
--account_id = 1097
select * from hz_parties where party_name = 'My_Party'
--party_id = 1284
--party_number = 1264
select * from hz_cust_accounts
where party_id = 1284
--cust_account_id = 1097
--account_number = 1053
select * from hz_parties
where party_name like 'My_Contact';
party_id = 5903, party_number = 5927

Answer 1

I wouldn't like to draw the schema diagram - but the SQL below returns both employee and customer information in a single query.
SELECT con.incident_id
, peo.full_name
, peo.first_name
, peo.last_name
, loc.location_code
, con.primary_flag
,'Employee' contact_type
, con.contact_point_type contact_point_type
, DECODE(con.contact_point_type, 'PHONE', phn.phone_number, 'EMAIL', peo.email_address, NULL) contact_point_value
FROM cs_hz_sr_contact_points con
, per_all_people_f peo
, hr_locations_all loc
, per_phones phn
WHERE con.party_id = peo.person_id
AND con.contact_type = 'EMPLOYEE'
AND peo.effective_start_date = ( SELECT MAX(peo2.effective_start_date)
FROM per_all_people_f peo2
WHERE peo2.person_id = peo.person_id )
AND con.contact_point_id = phn.phone_id(+)
UNION ALL
SELECT DISTINCT C.incident_id
, D.PERSON_FIRST_NAME||D.PERSON_LAST_NAME
, D.PERSON_FIRST_NAME
, D.PERSON_LAST_NAME
, c.primary_flag
,'Customer'
, a.contact_point_type
, DECODE(a.contact_point_type, 'PHONE', a.raw_phone_number, 'EMAIL', a.email_address, NULL) contact_point_value
FROM HZ_CONTACT_POINTS A
, AR_LOOKUPS B
, CS_HZ_SR_CONTACT_POINTS C
, HZ_PARTIES D
, HZ_RELATIONSHIPS R
, AR_LOOKUPS E
WHERE C.PARTY_ID = R.PARTY_ID(+)
AND ((D.PARTY_ID = C.PARTY_ID AND C.CONTACT_TYPE = 'PERSON') OR (D.PARTY_ID = R.SUBJECT_ID
AND C.CONTACT_TYPE = 'PARTY_RELATIONSHIP' AND D.PARTY_TYPE = 'PERSON' ))
AND C.CONTACT_POINT_TYPE = B.LOOKUP_CODE(+)
AND B.LOOKUP_TYPE(+) = 'COMMUNICATION_TYPE'
AND A.CONTACT_POINT_ID (+) = C.CONTACT_POINT_ID
AND D.PERSON_PRE_NAME_ADJUNCT = E.LOOKUP_CODE(+) AND E.LOOKUP_TYPE(+)= 'CONTACT_TITLE'
