I have a SQL statement which runs pretty slow, and I'm wondering if it will run faster if I use Except.
Except I can't figure out how to use Except. The SQL looks like this:
Select Name from Person where SSN not in (Select SSN from Paid)
Select Name from Person p
join Position q on q.Pos_Person_ID=p.person_ID
where not exists(select * from PAID as PD where Station=‘523’ and PD.ssn = P.ssn )
