Ok I got another fun one I got a table Site, which contains sites (Duh)
([Sell-to Customer No_] varchar(20),
[Name] varchar(50),
[Name 2] varchar(50),
[Address] varchar(50),
[Address 2] varchar(50),
[City] varchar(30),
[Contact] varchar(30),
[Country Code] varchar(10),
[Phone No_] varchar(30),
[GSM] varchar(30),
[Fax No_] varchar(30),
[PrintOnInvoice] tinyint,
[Post Code] varchar(20),
[Global Dimension 1 Code] varchar(20),
[Global Dimension 2 Code] varchar(20),
[NoSeries] varchar(10),
[Territory Code] varchar(10),
[Contact No_] varchar(20),
[Creation Date] datetime,
[Tender Date] datetime,
[Contact No_ 1] varchar(20),
[Business Relation 1] varchar(10),
[Contact No_ 2] varchar(20),
[Business Relation 2] varchar(10),
[Contact No_ 3] varchar(20),
[Business Relation 3] varchar(10),
[30bis Identification] varchar(30),
[Comments] tinyint)
This table is filled up with the help of the following query
select distinct
oh.Customer,ISNULL(UPPER(LEFT(od.Name1,50)),''),ISNULL(LEFT(od.Name2,50),''),ISNULL(UPPER(LEFT(od.Street1,50)),''),
ISNULL(LEFT(od.Street2,50),''),ISNULL(UPPER(LEFT(od.Place,30)),''),ISNULL(UPPER(LEFT(od.Name1,30)),'')
,ISNULL(UPPER(LEFT(od.Country,10)),''),ISNULL(LEFT(od.Telephone,30),''),'','',1,
ISNULL(LEFT(od.Postcode,20),''),'','','','','','1753-01-01 00:00:00.000','1753-01-01 00:00:00.000','','','','','','','',0
from dbo.Orderdelivery od
inner join dbo.Orderheader oh on od.OrderId = oh.OrderID
where 1 = 1
and od.Street1 IS NOT NULL
Now comes the fun part I get records that the same information except for a few fields
So I get for instance a site with Adress, City,Country filled in but with an empty postcode,
but i can also get the site again but then without a postcode.
In this case I want to keep the one with a postcode, but not all sites will have a postcode
Anyone got any ideas how to do this

Why you have used here where 1=1

It's a habit of mine to use where 1 =1 cause then when i need to add/remove filters I don't have to remove the where only 'and'

I would create 2 select statements as subqueries in your main query and join them using the columns that you know must be equal to uniquely define a record and then in the SELECT part of your statement, use CASE to return the fields with value.

It's not entirely clear what you want, but I think you are after selecting the "best" version of each delivery address, where "best" means it has a postcode.
So, use a
row_number() over(partition by oh.Customer order by od.Postcode DESC) as [Best]
then wrap your whole query inside a subquery (or CTE) and select WHERE [Best]=1
This will give you the first address for each customer that has a Postcode - while still returning an address for those that don't have a Postcode.
If you need to prioritise between the addresses (more than one with a postcode, more than one without), just add more columns / expressions to the ORDER BY part of the ROW_NUMBER function.
Of course, this is simplistic and some validation of the Postcode may be required to make sure that a simple value of "Z" doesn't get priority over "W12 8QT"

Can you post the DDL for Site, OrderHeader and OrderDetail as we might then understand the problem a little better.
What is the process for entering data into the OrderHeader and OrderDetail tables, is it a Manually typed in through a UI and then used to update the Site?

It's not entirely .... may be required to make sure that a simple value of "Z" doesn't get priority over "W12 8QT"
That's indeed what's required, the sites are also 'unique' per customer', but a site can have a different name.
Basically this is for an order delivery application for delivery of building materials to construction sites, on an order multiple sites can be present but each site belongs to 1 order and 1 customer.
The new application is in place so this is to pull the data over from the old system, the old system did not have a table to store sites since they were stored in the order delivery detail table which also contains what was being delivered. The old system didn't check whether the site is present or not. SO the Name of the site could differ as could the postcode and contact, although the latter really isn't that important in the new system.
This problem started affecting the link table between orders and sites where wrong sites got linked.
so I came up with the following
I use a row number to get the best postcode RNPC, and a row number for the best name RNC
WITH CTE
(
[Sell-to Customer No_],[Name],[Name 2],[Address],[Address 2],[City],[Contact],[Country Code],
[Phone No_],[GSM],[Fax No_],[PrintOnInvoice],[Post Code],[Global Dimension 1 Code],[Global Dimension 2 Code],
[NoSeries],[Territory Code],[Contact No_],[Creation Date],[Tender Date],[Contact No_ 1],[Business Relation 1],
[Contact No_ 2],[Business Relation 2],[Contact No_ 3],[Business Relation 3],[30bis Identification],[Comments],
RNPC,RNC) AS
(
select distinct
oh.Customer,ISNULL(LEFT(od.Name1,50),''),ISNULL(LEFT(od.Name2,50),''),ISNULL(UPPER(LEFT(od.Street1,50)),''),
ISNULL(LEFT(od.Street2,50),''),ISNULL(UPPER(LEFT(od.Place,30)),''),ISNULL(LEFT(od.Name1,30),'')
,ISNULL(UPPER(LEFT(od.Country,10)),''),ISNULL(LEFT(od.Telephone,30),''),'','',1,
ISNULL(LEFT(od.Postcode,20),''),'','','','','','1753-01-01 00:00:00.000','1753-01-01 00:00:00.000','','','','','','','',0,
ROW_NUMBER() OVER(PARTITION BY oh.Customer,od.Street1,od.Place,od.Country ORDER BY od.Postcode) As RNPC,
ROW_NUMBER() OVER(PARTITION BY oh.Customer,od.Street1,od.Place,od.Country ORDER BY od.Name1) As RNC
from VMSER_TP7VM.dbo.Orderdelivery od
inner join VMSER_TP7VM.dbo.Orderheader oh on od.OrderId = oh.OrderID
where 1 = 1
and od.Street1 IS NOT NULL
)
select [Sell-to Customer No_],Name,[Address],City,[Country Code],
ISNULL(CASE WHEN CTE.[Post Code] = ''
THEN (select top 1 [Post Code] from CTE t
where 1 = 1
and t.City = CTE.City
and CTE.City <> ''
and t.[Post Code] <> '')
ELSE CTE.[Post Code]
END,'')
[Post Code],
RNPC,RNC
from CTE
where 1 =1
--and RNPC = 1
and RNC > 1
--and Name = 'WERF BOSTOEN'
--and CTE.Address = 'DEPOT'
order by city,address
This also showcases why I use where 1 = 1, if anyone thinks this can be better please tell.
