Hi,

I have a query that result in this

 APPLICATIONID    APPLICATIONNAME      TO_APPID            TO_APPNAME 
35                               test0                              554                           Name1  
436                             test 1                                538                        Name2  
436                            test2                                542                        Name3    
436                            test3                                185                       Name4   
436                            test4                                123                       Name5

Try this:
SELECT DISTINCT APPID
FROM (SELECT APPLICATIONID AS APPID FROM MyTable UNION ALL
      SELECT TO_APPID AS APPID FROM MyTable) t1

Open in new window

Obviously, replace "MyTable" with whatever really is your table name. Good luck.

<very wild guess based only on the above set>
SELECT a.value 
FROM (
   SELECT APPLICATIONID as value, TO_APPNAME, 1 as sort_order
   FROM YOUR_TABLE
   UNION ALL
   SELECT TO_APPID as value, TO_APPNAME, 2 as sort_order
   FROM YOUR_TABLE) a
ORDER BY a.TO_APPNAME, a.sort_order

Looks like we cross-posted, sorry.  Please try both out, as we're not connected to your source of data so we can't test, giving dsacker's T-SQL priority as he posted first.

this query get me 

SELECT AFW.ApplicationID, AFW.ApplicationName, AFW.AppID_To AS To_AppID, AR.ApplicationName AS To_AppName

i guess if it the order is not important, here it is

select ApplicationID from [dbo].Application_From_View
union
select AppID_To from [dbo].Application_From_View

I am confused????

HainKurtSr. System AnalystCommented:
:) to be confused is normal... and you are confusing us by adding more info on every post, which changes the solutions...

try this, as is:

select AFW.ApplicationID  from (
	select ApplicationID from [dbo].Application_From_View
	union
	select AppID_To from [dbo].Application_From_View
) AFW inner join [dbo].AppRepository AR ON AFW.ApplicationID=AR.ApplicationID AND AR.retired=0

dsackerContract ERP Admin/ConsultantCommented:
Considering the progressive revelations of the table(s) involved, if you take HainKurt's suggestion, simply change it to:

select DISTINCT AFW.ApplicationID ...

And since the desired results are sorted, add:

ORDER BY ApplicationID

... at the bottom.

HainKurtSr. System AnalystCommented:
UNION eliminates duplicates, so no need for "DISTINCT"

agreed on second part, an order is always useful on application side... should always add some sort to queries, unless it is absolutely not necessary or creating performance issues...

PortletPaulfreelancerCommented:
Depending on what that view is doing, there may be no need for multiple queries and hence no need for either UNION or DISTINCT.

Please try this:
SELECT
      AR.ApplicationID
FROM [dbo].AppRepository AR
WHERE AR.retired = 0
ORDER BY
      AR.ApplicationID
;

Vitor MontalvãoMSSQL Senior EngineerCommented:
If you don't mind to have a row order column in the result then you can try this solution:
WITH App_CTE( AppID, RowID) AS 
(
	SELECT AFW.ApplicationID, ROW_NUMBER() OVER(ORDER BY AFW.ApplicationName, AR.ApplicationName ) AS Row
	FROM [dbo].Application_From_View AFW 
	LEFT OUTER JOIN [dbo].AppRepository AR ON (AFW.AppID_To=AR.ApplicationID) 
	WHERE AR.ApplicationName is not null and AR.retired=0 
	UNION ALL
	SELECT AFW.AppID_To, ROW_NUMBER() OVER(ORDER BY AFW.ApplicationName, AR.ApplicationName ) AS Row
	FROM [dbo].Application_From_View AFW 
	LEFT OUTER JOIN [dbo].AppRepository AR ON (AFW.AppID_To=AR.ApplicationID) 
	WHERE AR.ApplicationName is not null and AR.retired=0 
)
SELECT AppId, MIN(RowID)
FROM App_CTE
GROUP BY AppID
ORDER BY 2, 1
