I just can't figure this one out! I have the following tables:

Contacts
id int,
lastname varchar(255),
...

qualifier
id int,
description varchar(255),
...

ContactQualities
contactid int,
qualifierid int,
...

I need to formulate a SQL stored procedure which will produce a cursor of contacts which must have a list of qualities and must not have a list of differennt qualities.

parameter 1 looks like this
'01,05...'
parameter 2 looks like this
'02,06...'

Any suggestions?
