Question

I have a table a which have multiple entry of artikelNr for it to contain multiple Enhet values just like in the picture below, I would like to query all the unique artikelNr which are not associated with Enhet=5.

There is another table which contains unique artikelNr only, if it can help. I am using MS SQL in my local database.

artikelNr enhet                      output should look like
  1         0                        artikelnr          enhet 
  1         5                          2                 0 or 3  no problem
  1         8                          6                 0 or 8 or 3 no problem 
  1         3
  2         0
  2         3 
  4         5  
  4         0  
  4         1  
  4         2
  6         8

Answer 1

Try this

    Select distinct (artikelNr) from ArtAlias where artikelNr NOT IN 
    (select artikelNr from ArtAlias where enhet = 5) order by ArtikelNr
