Here is my code
sELECT PhoneID,DegreeYear

from Email_Table inner join School_Table
on phnid = schlid
where schlschool = '15'
and schoolConc not in (select schoolConc
from School_Table
where schoolConc in
('7101a','7101b','7101c','7101d','7101e','7101f',
'7101g','7101i'))

The query is supposed to eliminate concentrations in parenthesis. When I run the query it shows the concentrations it is supposed to eliminate.
Is there another way I can write this or is my parenthesis in the wrong place? Should I be selecting the schoolID instead of the schoolConc in the nested select statement?

I don't see the need for the subquery.

select PhoneID, DegreeYear
from Email_Table
join School_Table
on phnid = schlid
where schlschool = '15'
and schoolConc not in ('7101a','7101b','7101c','7101d','7101e','7101f',
'7101g','7101i')
