Dear All,
Need help with query.
I am using three tables
1.Users
2.Subscriptions
3.Transactions

Requirement:
Generate a list of unique email addresses with the latest name, gender
and age for a user with that email

The selection criteria limits the list to users which never subscribed to
anything; or;
users with inactive subscriptions; or;
users with active subscriptions that renewed between Sep 1st and Sep
30th of any year

answer should be:
Email Gender Age Name
a@a.com m 31 robert
b@b.com f 22 lulu
c@c.com f 08 kim
d@d.com m 22 Jay
e@e.com f 60 Will

Below is the DDL along with insert data script
