    • Article Type: General
    • Product: Aleph
    • Product Version: 20

    What SQL I can use to get:

    A. the patron ID with most loans in xxx50?

    B. all patrons who have more than X loans in xxx50?

    This SQL will give you both of them:

    SQL> select z36_id, count(*) from z36 group by z36_id order by count(*) desc;
