SQL får flera kolumner i en kolumn

Detta är ett skott i mörkret eftersom vi inte riktigt känner till dina data, men om du gillar din befintliga fråga kan det vara möjligt att helt enkelt använda den två gånger men med en where-klausul som så:

SELECT
-- Common stuff?
ISNULL(Sales.ActivityId, Other.ActivityId), ISNULL(Sales.ScheduledStart, Other.ScheduledStart), ISNULL(Sales.OwnerIdName, Other.OwnerIdName), ISNULL(Sales.AccountIdName, Other.AccountIdName), ISNULL(Sales.new_ContactPersonName, Other.new_ContactPersonName), ISNULL(Sales.[Subject], Other.[Subject]), ISNULL(Sales.new_ColderNotes, Other.new_ColderNotes)
-- Sales stuff?
, Sales.AccountId, Sales.ContactId, Sales.SystemUserId, Sales.OptionalOwner, Sales.OptionalContact, Sales.OptionalAccount, Sales.PartyId, Sales.ParticipationTypeMask, Sales.RequiredContact, Sales.RequiredAccount, Sales.RequiredOwner, Sales.new_BusinessUnit
-- Other Stuff?
, Other.AccountId, Other.ContactId, Other.SystemUserId, Other.OptionalOwner, Other.OptionalContact, Other.OptionalAccount, Other.PartyId, Other.ParticipationTypeMask, Other.RequiredContact, Other.RequiredAccount, Other.RequiredOwner, Other.new_BusinessUnit
FROM
(
    SELECT DISTINCT

            Contact_1.FullName AS RequiredContact, Account.Name AS RequiredAccount, SystemUser.FullName AS RequiredOwner, Account.new_BusinessUnit
