Question

EDIT:This did it:

  SELECT DISTINCT profileid 
FROM profilesrelevation 
WHERE profileid NOT IN (
  SELECT profileid FROM profiles
)

I need to get the profileid values that exist in profilesrelevation table but not in profiles table

profiles table have 8107 diffrent “profileid” values while profilesrelevation table has 8380 diffrent “profilesid” values…

profiles.profileid
profilesrelevation.profileid

select * from profiles, profilesrelevation 
where profilesrelevation.profileid != profiles.profileid  

does not work , how?

Answer 1

You’ll be wanting to use a set:

SELECT DISTINCT profileid 
FROM profilesrelevation 
WHERE profileid NOT IN (
  SELECT profileid FROM profiles
)

This selects all rows/columns from table:profilesrelevation where the profileid of the row isn’t also in table:profiles 🙂

Updated: include distinct since it would appear profileid isn’t unique in the profilesrelevation table.
