[Koha] Correct SQL for getting count of active borrowers

[Lola McKee]

Can someone tell me the correct SQL to get a count of active borrowers? 
 
Do I need to pull from issues or old_issues and what is the differences
and or reasoning. 
 
We used the SQL from Koha SQL Reports Library "List Active Patrons by
Category for a Specific Month" Code = SELECT YEAR(issuedate),
MONTH(issuedate), categorycode, COUNT(DISTINCT borrowernumber) FROM
old_issues LEFT JOIN borrowers USING (borrowernumber) GROUP BY
YEAR(issuedate), MONTH(issuedate), categorycode

 

Also do we want to use DISTINCT borrowernumber or just borrowernumber?

 

Thanks,
