This may be more of a DB view question, so Admin, please move to the right spot if necessary.
I am creating a query of active donors who have given in the last two years (Gift date 01/01/022 to today) and who DOES NOT have a certain constituent code with an active date before a certain day.
Basically what I am trying to do is build a mailing list for active donors who have not previously attended one of our quarterly donor socials in the last year. If there is a cleaner way to do that, please feel free to share.
Thank you in advance.
