I have  a table called Passes1 that shows every ticket sale we have ever made.
I want to run a query on customers that bought a ticket in 2015 but have not bought yet in 2016

I have this query -
SELECT * FROM Passes1 as pa WHERE NOT EXISTS (Select * from Passes1 as pa1 WHERE pa.THID=pa1.THID AND pa1.Year = '2016') AND Year ='2015'

Where am I off?
