Hi, i'm learning the sql programming and i love it, I have a sql view (#1) that shows me something like this :

ARTCODE |QUANTITY | LASTMOVE |
articulo1 | 5 | 2013-01-01|
articulo1 | 2 | 2013-05-07|
articulo2 | 1 | 2013-07-19|
articulo3 | 6 | 2013-06-16|

and I need just grouping by artcode and showing only the max(lastmove) the most recent date by item (artcode)like this :

ARTCODE |QUANTITY | LASTMOVE |
articulo1 | 2 | 2013-05-07|
articulo2 | 1 | 2013-07-19|
articulo3 | 6 | 2013-06-16|

This is my code :

SELECT TOP (100) PERCENT dbo.gbkmut.artcode, MAX(dbo.gbkmut.datum) AS LastMove, GETDATE() AS DateNow, DATEDIFF(DAY, MAX(dbo.gbkmut.datum), GETDATE())
AS DayLastMoveUntilNow, dbo.gbkmut.aantal, dbo.gbkmut.docnumber
FROM dbo.gbkmut WITH (NOLOCK) INNER JOIN
dbo.grtbk WITH (NOLOCK) ON dbo.grtbk.reknr = dbo.gbkmut.reknr LEFT OUTER JOIN
dbo.humres AS SM WITH (NOLOCK) ON SM.res_id = dbo.gbkmut.sysmodifier LEFT OUTER JOIN
dbo.humres AS SC WITH (NOLOCK) ON SC.res_id = dbo.gbkmut.syscreator LEFT OUTER JOIN
dbo.cicmpy WITH (NOLOCK) ON dbo.cicmpy.debnr = dbo.gbkmut.debnr AND dbo.cicmpy.debnr IS NOT NULL AND dbo.gbkmut.debnr IS NOT NULL LEFT OUTER JOIN
dbo.cicmpy AS c1 WITH (NOLOCK) ON c1.crdnr = dbo.gbkmut.crdnr AND c1.crdnr IS NOT NULL AND dbo.gbkmut.crdnr IS NOT NULL LEFT OUTER JOIN
dbo.humres WITH (NOLOCK) ON dbo.gbkmut.res_id = dbo.humres.res_id LEFT OUTER JOIN
dbo.cicmpy AS c3 WITH (NOLOCK) ON dbo.gbkmut.orderdebtor = c3.cmp_wwn AND dbo.gbkmut.orderdebtor IS NOT NULL AND c3.cmp_wwn IS NOT NULL
LEFT OUTER JOIN
dbo.magaz WITH (NOLOCK) ON dbo.magaz.magcode = dbo.gbkmut.warehouse AND dbo.magaz.magcode IS NOT NULL AND dbo.gbkmut.warehouse IS NOT NULL
LEFT OUTER JOIN
dbo.Items WITH (NOLOCK) ON dbo.Items.ItemCode = dbo.gbkmut.artcode AND dbo.Items.ItemCode IS NOT NULL AND dbo.gbkmut.artcode IS NOT NULL
LEFT OUTER JOIN
dbo.kstpl WITH (NOLOCK) ON dbo.gbkmut.kstplcode = dbo.kstpl.kstplcode AND dbo.gbkmut.kstplcode IS NOT NULL AND dbo.kstpl.kstplcode IS NOT NULL
LEFT OUTER JOIN
dbo.kstdr WITH (NOLOCK) ON dbo.gbkmut.kstdrcode = dbo.kstdr.kstdrcode AND dbo.gbkmut.kstdrcode IS NOT NULL AND dbo.kstdr.kstdrcode IS NOT NULL
WHERE (dbo.gbkmut.transtype IN ('N', 'C', 'P', 'F')) AND (dbo.gbkmut.transsubtype = 'B') AND (dbo.grtbk.bal_vw IN ('W')) AND (dbo.gbkmut.ReminderCount <= 15)
GROUP BY dbo.gbkmut.artcode, dbo.gbkmut.aantal, dbo.gbkmut.docnumber
ORDER BY dbo.gbkmut.artcode, lastmove

I did a second view (#2) because I didn't know if in this view (#1) I could grouping by the code with the lastmove but in this second view I can groupyn I don't know my error, this is the code and this code shows me the same of the view #1:

SELECT TOP (100) PERCENT artcode, aantal AS Quantity, docnumber, MAX(LastMove) AS LastMove, DayLastMoveUntilNow, DateNow
FROM dbo.Vw_LastMove
GROUP BY artcode, aantal, docnumber, LastMove, DayLastMoveUntilNow, DateNow
ORDER BY artcode

Please I need your help

What are you trying to achieve with your first view, I think there is room to improve your query.
Would you be able to post your DDLs and some example data following these guidelines: http://weblogs.sqlteam.com/brettk/archive/2005/05/25/5276.aspx

If I read the question right, this suggestion might work for you:

              ,DATEDIFF(DAY, MAX(dbo.gbkmut.datum), GETDATE()) AS DayLastMoveUntilNow

                 ,lastmove
       ) AS tmp
 ORDER BY artcode
         ,lastmove

green=outside of the subselect
pink=code moved outside of subselect
black="order by" also on the outside of subselect, as we can't expect the engine to keep the sort order (it probably will, but MS don't guarantee it)
red=let the optimizer decide whether or not lock is necessary, so normally this is not needed
orange=brackets are not necessary here

ps.: There might be syntax error(s) as I don't have access to my database at the moment (notepad to the rescue

)

I don't know about sql so I did the second view because someone said me that in the original view this was impossible, I don't know how I can make the ddls that you mencioned, the only I need from the first view is that this view shows me all the records of every item and i'm trying to show only the last movement of every item and the quantity sold.

Thanks for your help.

I did it that you said but still without chooosing the artcode and his last movement, its showing me all the transactions and dates of every artcode, this Is the code with all I understood about your suggestions :

SELECT artcode
      ,LastMove
      ,aantal
      ,docnumber
  FROM (SELECT TOP (100) PERCENT dbo.gbkmut.artcode
              ,MAX(dbo.gbkmut.datum) AS LastMove

I think I understand your question now.
Try this:
