Hi again
Apologies for not making my problem clear. I shall try again.
The database table looks something like this 
id someotherdata groupcode
1     blah                  wek134
2      foo                  htw456
3     baa                   twe546
4     soc                   wek134

[download]
In a nutshell I want to create a list that for id 1 lists all other entries without the groupcode wek134, and then for id 2 lists all other entries without the groupcode htw456 and so on
The actual analysis comes later. This is just to get the data in the correct format.
Thanks a lot
