Possibly this Ibm i VIEW is creating duplicated records? - db2

I am seeing what seems to be duplicate records from this view. Do you think this View is causing duplicate records?
create view astccdta.acaudia AS
( select d.IARCC9,b.ItQty#,a.IhDocd,b.ItPRT#
from astdta.OEINHDIH a
join astdta.ICDETLIT b on
b.Itcom# = a.IhCom#
and
b.ItTrn# = a.IhIdc#
left join astdta.ICECTLCT c on
c.CtCom#= b.ItCom# and
c.CtCtr# = ' ' and
c.CtPrt# =b.ItPrt#
left join astdta.Audia d
on d.IAprt# = b.ItPrt#
where b.ItTscc = 'I' and a.IHDOCD > 20120105
and d.IARCC9 > ''
)

Postgres Error: missing FROM-clause entry for table

I have a query and am using left joins. I have the left join clause as follows:
left outer join ( select pup.brokerage_code, pcz.zip, count (pup.aggregate_id) as VerifiedAgentCount
from partner_user_profiles pup
join partner_user_roles pure on pure.user_profile_id = pup.id
join profile_coverage_zips pcz on pcz.profile_id = pup.id
where lower(pure.role) = 'agent'
and pup.verification_status like 'Verified%'
group by pup.brokerage_code, pcz.zip) vac on vac.brokerage_code = b.brokerage_code and pcz.zip = bcz.zip
However I am getting the error message saying that I am missing the FROM entry clause for "pcz" however I aliased the table in the join clause so I am not sure what is wrong.
You have defined the table alias pcz within the sub-select however the alias no longer exists when the outside the sub-select. At the point you have used it the appropriate alias is the one for the entire sub-select, in this case vac. So: vac.zip = = bcz.zip
left outer join ( select pup.brokerage_code, pcz.zip, count (pup.aggregate_id) as VerifiedAgentCount
from partner_user_profiles pup
join partner_user_roles pure on pure.user_profile_id = pup.id
join profile_coverage_zips pcz on pcz.profile_id = pup.id
where lower(pure.role) = 'agent'
and pup.verification_status like 'Verified%'
group by pup.brokerage_code, pcz.zip
) vac on vac.brokerage_code = b.brokerage_code
and vac.zip = bcz.zip

how can one table name used more than once in query of postgresql

I create view in the postgresql that for write query but error message display table name used more than once. How to solve this problem?
Query
SELECT
tbcitizen.firstname || '-' || tbcitizen.middlename || '-' || tbcitizen.familyname as firstname,
tbcitizen.dateofbirth,
tbcity.cityname,
tbcontact.contactdetails,
tbcitizen.citizenidp
FROM
public.tbcitizen,
public.tbaddress,
public.tbcity,
public.tbcontact
INNER JOIN
tbcontact ON tbcitizen.citizenidp = tbcontact.referenceidf AND tbcontact.referencetypeidf = 1 AND
tbcontact.isprimery = 1 INNER JOIN
tbaddress ON tbcitizen.citizenidf = tbaddress.referenceidf AND tbaddress.referencetypeidf = 1 AND
tbaddress.isprimery = 1 INNER JOIN
tbcity ON tbaddress.cityidf = tbcity.cityidp
WHERE
tbaddress.referencetypeidf = tbcitizen.citizenidp AND
tbaddress.referenceidf = tbcitizen.citizenidp AND
tbaddress.cityidf = tbcity.cityidp
Error = table name "tbcontact" specified more than once
Thanks
As the error states that - your table tbcontact used 2 times as the source table. So it creates ambiguity for the postgres database engine. So to resolve this issue you have to use table alias with different name.
Hope it'll help you.

Cannot get view to work on SQL Server

I am trying to create a view that includes columns froms several tables.
This is what it looks like:
And this is my query:
SELECT
Billing.WebPortalBilling.WebPortalBillingId,
Billing.WebPortalBilling.CorporationId,
Billing.WebPortalBilling.TokenId,
Billing.WebPortalBilling.GatewaySupportFee,
Billing.WebPortalBilling.GatewayPerTransactionFee,
Billing.WebPortalBilling.PortalPerCustomerFee,
Billing.WebPortalBilling.PortalSupportFee,
Customer.Account.AccountNumber,
Billing.WebPortalBilling.IsActive,
Customer.Customer.Name,
Customer.Customer.TaxCode,
Company.CorporationStructure.Branch
FROM
Company.CorporationStructure
RIGHT OUTER JOIN
Customer.Account ON Company.CorporationStructure.CorporationStructureId = Customer.Account.CorporationStructureId
RIGHT OUTER JOIN
Customer.Customer ON Company.CorporationStructure.Branch = Customer.Customer.Branch
RIGHT OUTER JOIN
Billing.WebPortalBilling ON Customer.Account.CorporationId = Billing.WebPortalBilling.CorporationId
WHERE
(Billing.WebPortalBilling.IsActive = 1)
It's only returning 1 record, which is not correct. I'm trying to tie the Customer's name back to the WebPortalBilling table along with the account number and branth in the other two tables.
I'm new to sql, so be kind.
Thanks!
As commented the where is killing the outer
Try
SELECT
Billing.WebPortalBilling.WebPortalBillingId,
Billing.WebPortalBilling.CorporationId,
Billing.WebPortalBilling.TokenId,
Billing.WebPortalBilling.GatewaySupportFee,
Billing.WebPortalBilling.GatewayPerTransactionFee,
Billing.WebPortalBilling.PortalPerCustomerFee,
Billing.WebPortalBilling.PortalSupportFee,
Customer.Account.AccountNumber,
Billing.WebPortalBilling.IsActive,
Customer.Customer.Name,
Customer.Customer.TaxCode,
Company.CorporationStructure.Branch
FROM
Company.CorporationStructure
RIGHT OUTER JOIN
Customer.Account ON Company.CorporationStructure.CorporationStructureId = Customer.Account.CorporationStructureId
RIGHT OUTER JOIN
Customer.Customer ON Company.CorporationStructure.Branch = Customer.Customer.Branch
RIGHT OUTER JOIN Billing.WebPortalBilling
ON Customer.Account.CorporationId = Billing.WebPortalBilling.CorporationId
AND Billing.WebPortalBilling.IsActive = 1
Try this, I think left joins are clearer.
SELECT
B.WebPortalBillingId,
B.CorporationId,
B.TokenId,
B.GatewaySupportFee,
B.GatewayPerTransactionFee,
B.PortalPerCustomerFee,
B.PortalSupportFee,
C.AccountNumber,
B.IsActive,
C.Name,
C.TaxCode,
CS.Branch
FROM Customer.Customer C
LEFT JOIN Company.CorporationStructure CS ON CS.Branch = C.Branch
LEFT JOIN Customer.Account A ON CS.CorporationStructureId = A.CorporationStructureId
LEFT JOIN Billing.WebPortalBilling B ON A.CorporationId = B.CorporationId
WHERE B.IsActive = 1

Returning distinct columns from left outer join in db2

SELECT
nzy.NZPYYD
,nzy.NZZSYG
,nzy.NZJRYG
,acn.ANITCD
FROM
ACNTRA acn
LEFT OUTER JOIN NZYTFL nzy
ON (
nzy.NZCNO1 = acn.ANCNO1
AND nzy.NZCNO2 = acn.ANCNO2
AND nzy.NZCNO3 = acn.ANCNO3
AND nzy.NZCNO4 = acn.ANCNO4
AND nzy.NZCNO5 = acn.ANCNO5
AND nzy.NZSLKI = acn.ANSLKI
AND nzy.NZDLTM = ''
)
WHERE
acn.ANDLTM = ''
AND acn.ANTKCD = '1029'
AND nzy.NZTXKB = 1
The problem here is it gives 2 rows result.I want to get one unique row from the result of left outer join .Any help?
If both rows are identical, try
SELECT DISTINCT
nzy.NZPYYD
,nzy.NZZSYG
,nzy.NZJRYG
,acn.ANITCD
If not, you can try to SUM(), CONCAT(), MAX() or whatever the column with different values.
Difficult to be more precise without a sample output.
