QUESTION
Newbie here. Thanking you in advance for your help!
I have the following code to count unique records based on 3 data elements:
count(distinct concat(a.emp_nbr, b.acct_nbr, c.event_dt))
The event_dt is stored in the db as [DATE].
the issue is that i don't want to EXCLUDE 'DD' in the concat match statement. I want to match based on the MM/YYYY only. I believe the answer is to convert the [DATE] to MM/YYYY.
Ultimately i want to count distinct records based on emp_nbr, acct_nbr and mm/yyyy of event_dt.
Thanks!

You can use reco like any standard Python library.
