hope this fix your issue I could be completely misinterpreting your table schema, but it looks to me like you really are trying to do something like this:
code :
select 
    ...
from User_Profile up
inner join User_Friend uf
on up.ProfileId = uf.ProfileId1 and uf.ProfileId = up.ProfileId
where up.UserId = @UserId and up.FirstName like '%' + @FirstName + '%'
union all
select 
    ...
from User_Profile up
inner join User_Friend uf
on up.ProfileId = uf.ProfileId and uf.ProfileId1 = up.ProfileId
where up.UserId = @UserId and up.FirstName like '%' + @FirstName + '%'

This might help you If your data from the two queries is joinable based on the numeric portion of the Code and Position then you might be able to use something like this:
code :
select q1.position,
  q1.name,
  q2.value,
  q2.code
from
(
  SELECT EWND.Position,
    NKey = CASE WHEN ISNULL(Translation.Name, '') = '' THEN EWND.Name
                ELSE  Translation.Name END, Unit = EW_N_DEF.Units                               
  FROM EWND
  INNER JOIN EW_N_DEF 
    ON EW_N_DEF.Nutr_No = EWND.Nutr_No
  LEFT JOIN Translation 
    ON Translation.CodeMain = EWND.Nutr_no
  WHERE Translation.CodeTrans  = 1
) q1
full outer join
(
  SELECT value, code
  FROM 
  (
     SELECT N1,N2,N3,N4,N5,N6,N7,N8,N9,N10,N11,N12,N13,N14,N15,N16,N17,N18,N19,N20,N21,N22,N23,N24,N25,N26,N27,N28,N29,N30,N31,N32,N33,N34
     FROM EWNVal 
     WHERE Code=6035
  ) Test
  UNPIVOT
  (
    Value FOR NUTCODE IN 
        (N1,N2,N3,N4,N5,N6,N7,N8,N9,N10,N11,N12,N13,N14,N15,N16,N17,N18,N19,N20,N21,N22,N23,N24,N25,N26,N27,N28,N29,N30,N31,N32,N33,N34)
  )AS test
) q2
  on q1.Position = right(q1.code, len(q1.code)-1)

it should still fix some issue I am trying to write a select statement with a right join (to clients), that will find a specific value in the join table - but ONLY if that is the most recent value for each client (ignoring blanks and nulls). , Please try this
code :
SELECT activity.id AS activityid
    , activity.type
    , activity.date
    , clients.id AS clientid
    , clients.name
FROM activity
LEFT JOIN activity AS other_activities
  ON activity.ClientID  = other_activities.ClientID
    AND activity.date < other_activities.date
LEFT JOIN clients
  ON activity.ClientID = clients.id
WHERE activity.type = 500
  AND other_activities.ClientID IS NULL;

I wish this helpful for you One possible way to do this would be to use a pair of LEFT joins, and then determine whether to return B.adid depending on whether a match has been found on C:-
code :
SELECT A.*, 
    IF(C.bfid IS NULL, NULL, B.bid), 
    IF(C.bfid IS NULL, NULL, C.cid), 
    IF(C.bfid IS NULL, NULL, C.bfid)
FROM A
LEFT OUTER JOIN B ON A.bfid = B.bid
LEFT OUTER JOIN C ON B.bid = C.bfid

Hope that helps Selecting specific categories works fine: , I think you want:
code :
SELECT wp.ID, wp.post_content, wp.post_title
FROM wp_posts wp
WHERE NOT EXISTS (SELECT 1
                  FROM  wp_term_relationships tr 
                  WHERE tr.object_id = wp.id AND
                        tr.term_taxonomy_id IN (17, 19)
                 );
SELECT wp.ID, wp.post_content, wp.post_title
FROM wp_posts wp JOIN
     wp_term_relationships tr 
     ON tr.object_id = wp.id
GROUP BY wp.ID, wp.post_content, wp.post_title
HAVING SUM( CASE WHEN tr.term_taxonomy_id IN (17, 19) THEN 1 ELSE 0 END) = 0;
