The following query is giving an error, can you help ?
Can you order by 2 fields in the ROW_NUMBER() expresssion?

=================================================================

SELECT (case when client_address.client_address_id = client.client_address_id
then 0
else 1
end) as main_id ,

'"'+CLIENT.Client_Code+'"',
ROW_NUMBER() OVER (PARTITION BY CLIENT_CODE ORDER BY CLIENT_CODE, main_id) AS Address_Number,
'"'+CLIENT.Client_Name+'"',
'"'+ADDRESS.Line_1+'"',
'"'+ADDRESS.Line_2+'"',
'"'+ADDRESS.Line_3+'"',
'"'+Town.Description+'"',
'"'+County.Description+'"',
'"'+Address.Postcode+'"',
'"'+Country.Description+'"',
'"'+CLIENT_ADDRESS.Invoice_YN+'"',
'"'+CLIENT_ADDRESS.Site_YN+'"'

FROM CLIENT
Join CLIENT_ADDRESS on CLIENT.Client_Id = CLIENT_ADDRESS.Client_Id
Inner join ADDRESS on CLIENT_ADDRESS.Address_Id = ADDRESS.Address_ID
Inner Join TOWN On ADDRESS.Town_Id = TOWN.Town_Id
Inner Join COUNTY On ADDRESS.County_Id = COUNTY.County_Id
Inner Join COUNTRY On ADDRESS.Country_Id = COUNTRY.Country_Id

ORDER BY CLIENT_NAME, CLIENT_CODE, main_id

i didnt understand the purpose of concatenating all these quotes, but anyways if you want to do this you need to CAST all the non varchar fields to varchar like '"'+ CAST(CLIENT.Client_Code AS varchar(10))+'"'...
Your ROW_NUMBER looks fine . as per current logic it groups by CLIENT_CODE and within group numbers them as per order of main_Id. Not sure what else you're expecting. can you elaborate?
