Subqueries with more results

[reentry]

Hi,

I Have some troubles with a SQL Statment. The result should be a list of the same Articles with current price and calculated price per kg.

Each article has more prices.

The querie works fine with 1 article:

SELECT Preis.ArtikelID, Preis.BruttoPreis, Artikel.Bezeichnung, Artikel.Einheit, Artikel.Liefereinheit, Artikel.Gewicht, Artikel.ArtikelNr, round((Preis.BruttoPreis / Artikel.Gewicht *1 ),2) as KiloPreis
FROM Preis INNER JOIN Artikel ON Preis.ArtikelID = Artikel.ArtikelID
WHERE (((Preis.Preisid)=
                                 (SELECT Max(Preis.PreisID)
                                  FROM Preis WHERE Artikelid = 10113)));

My problem is if i try to search for all Artikel which contains for example orange...

I thought this would work:

SELECT Preis.ArtikelID, Preis.BruttoPreis, Artikel.Bezeichnung, Artikel.Einheit, Artikel.Liefereinheit, Artikel.Gewicht, Artikel.ArtikelNr, Round((Preis.BruttoPreis/Artikel.Gewicht*1),2) AS KiloPreis, Artikel.Bezeichnung
FROM Preis INNER JOIN Artikel ON Preis.ArtikelID = Artikel.ArtikelID
WHERE (((Preis.Preisid) = 
                                   (SELECT Max(Preis.PreisID) 
                                    FROM Preis WHERE Artikelid IN 
                                                                             (SELECT ArtikelID 
                                                                               FROM Artikel WHERE Bezeichnung like '*Orange*'))));

I get 1 Article instead of all articles which contain Orange... I think the problem is the MAX function but i have no idea how i can solve it.



Does anyone have an idea ? or solution ?

If you want the most recent price record for each article, consider TOP N query: http://allenbrowne.com/subquery-01.html#TopN

I considered your hint ( i created the below statement) and i get a better result, but now i get lots of duplicates Seen in Table below. There are exactly 31 Articles which have orange in their name, thats the reason why i chose TOP 31. Dont be irretated by the empty cells, i am working with some test data therefore there are lots of data missing.

How can i reduce these Duplicates because he chose not only the current price id? Group by doesnt work and if i use DISTINCT the sql staments seems to be in an endless Loob ..

SELECT Preis.ArtikelID, Preis.BruttoPreis, Artikel.Bezeichnung, Artikel.Einheit, Artikel.Liefereinheit, Artikel.Gewicht, Artikel.ArtikelNr, Round((Preis.BruttoPreis/Artikel.Gewicht*1),2) AS KiloPreis, Artikel.Bezeichnung
FROM Preis INNER JOIN Artikel ON Preis.ArtikelID = Artikel.ArtikelID
WHERE (((Preis.Preisid) in (Select TOP 31 Preis.PreisID From Preis Where Artikelid IN (Select ArtikelID from Artikel Where Bezeichnung like '*Orange*'))));

The PreisID values are unique, therefore the records are not duplicates.

Apparently these tables have a 1-to-many relationship. One of the tables has multiple records with the same ArtikelID. Therefore, joining these tables appears to 'duplicate' data from the other table.

U are right they arent dublicates wrong term, but i need only the data for the highest Price ID for each article ( article to price is a 1 to n relationship).

Please show us more of your table designs.
As June says, these are not duplicates.

And after seeing your latest post ( I was writing) which of these do you want since the Price is same in all 3 records???

28452	10316	kof0541	Orangen 15 kg Übersee		0	0	19,5
28302	10316	kof0541	Orangen 15 kg Übersee		0	0	19,5
30969	10316	kof0541	Orangen 15 kg Übersee		0	0	19,5

The link I posted shows how to get the TOP n for each group - in your case the groups are ArtikelID.

If you eliminate the PreisID field, could do a GROUP BY or DISTINCT query.

@
Always the one with the highest PreisID in this case this one

30969

10316

kof0541

Orangen 15 kg Übersee

19,5

Because all other arnt calculated with the current price.
