union 2 datasets to fill in empty fields

Can I union 2 select statements so that similar records will combine fields, such as
select names.id, names.first, names.last, '' as address
from tblnames
union
select addrs.nameid, '' as first, '' as last, addrs.address
from addrs
and the result would be like
id   first    last     addr
1     Tom  Jones   123 Maple
2     Jon   Smith     342 1st
etc
I'm trying something similar, but, I get (i've attached my code, but, it's much different...just trying to show what's happening)
id     name     email         phone
1      Tom     1@2.com
1      Tom                         123-345
2      Jon       3@2.com
2      Jon                          121-545
Select	DPid1.WebID, Contact1.Name as DP, Contact1.Email as DPEmail, '' as GM, '' as GMEmail
From	tblsfContact as Contact1 Inner Join
		(
		SELECT	WebIDs.WebID, MIN(contact.sfContactID) as ContactID
		FROM	tblsfInstalledBase AS Prod INNER JOIN
				tblHistWebIDDetails AS WebIDs ON Prod.sfWebID = WebIDs.sfWebID LEFT OUTER JOIN
				tblsfContact AS Contact ON WebIDs.sfAccntID = Contact.sfAccntID
		WHERE	(WebIDs.Period = DATEADD(mm, DATEDIFF(mm, 0, GETDATE()), 0)) AND (Prod.ProductCode = '14.285.00') AND (WebIDs.HasProCare = 0) AND 
				(WebIDs.HasSearch = 0) AND (Contact.Status = 'Active') AND (Contact.Role LIKE '%Dealer Principal%') AND (Contact.Email IS NOT NULL) 
		GROUP BY WebIDs.WebID
		) as DPid1 on DPid1.ContactID = Contact1.sfContactID
UNION
Select	DPid.WebID, '' as DP, '' as DPEmail, Contact.Name as GM, Contact.Email as GMEmail
From	tblsfContact as Contact Inner Join
		(
		SELECT	WebIDs.WebID, MIN(contact.sfContactID) as ContactID
		FROM	tblsfInstalledBase AS Prod INNER JOIN
				tblHistWebIDDetails AS WebIDs ON Prod.sfWebID = WebIDs.sfWebID LEFT OUTER JOIN
				tblsfContact AS Contact ON WebIDs.sfAccntID = Contact.sfAccntID
		WHERE	(WebIDs.Period = DATEADD(mm, DATEDIFF(mm, 0, GETDATE()), 0)) AND (Prod.ProductCode = '14.285.00') AND (WebIDs.HasProCare = 0) AND 
				(WebIDs.HasSearch = 0) AND (Contact.Status = 'Active') AND (Contact.Role LIKE '%General Manager%') AND (Contact.Email IS NOT NULL) 
		GROUP BY WebIDs.WebID
		) as DPid on DPid.ContactID = Contact.sfContactID

dont use UNION, use inner join and isnull
example

select ISNULL(A.FirstName, B.FirstName) FirstName, ISNULL(A.LastName, B.LastName) LastName
from People A
inner join People B on B.ID = A.ID

thanks, I'll try....so, union doesn't do that, am I confused with my Access days (or just totally confused)?

Union will just leave null spaces in between

not UNION... you may need a FULL OUTER JOIN  (if data is not guaranteed to be on both tables..


select coalesce(a.id,b.nameid) as id
     , a.first, a.last, b.address
from tblnames as a
full outer join addrs as b
 on a.id=b.nameid
select addrs.nameid, '' as first, '' as last, addrs.address
from addrs

hmmmm....
I think I have something different. I'm trying to add fields to the first dataset. So,
select names.id, names.first, names.last, '' as address
from tblnames
union
select addrs.nameid, '' as first, '' as last, addrs.address
from addrs
tblnames does not have a field addrs, so, I want to "append" it on to the results, so, that the list from tblnames will also include the addresses.
