Hi Jennifer,

First, check with your system administrator to make sure you have access to
your Evergreen database, either through psql (command line) or a GUI
(PGAdmin).

Then, I would recommend watching Rogan Hamby's excellent presentation from
the 2014 Evergreen conference - SQL for Librarians:
https://youtu.be/3Iz-HFiDq6E

Below is the query I used. It took me a long time and a lot of practice to
learn how to write something like this, so don't worry if you struggle at
first. I probably have some bad habits and certainly don't know all there
is to know. For instance, if I wanted to be really proper, I would define
the type of join I'm using. Default is an inner join, which means only
values that have matching values in both tables will appear in the output
(think the part where the two circles intersect in a ven diagram).

SELECT DISTINCT ON (ahr.id) ahr.request_time, acard.barcode,
au.family_name, au.first_given_name, rmsr.title, rmsr.tcn_value
FROM action.hold_request ahr
JOIN actor.usr au ON ahr.usr = au.id
JOIN actor.card acard ON au.card = acard.id
JOIN action.hold_copy_map ahcm ON ahr.id = ahcm.hold
JOIN asset.copy ac ON ahcm.target_copy = ac.id
JOIN asset.call_number acn ON ac.call_number = acn.id
JOIN reporter.materialized_simple_record rmsr ON rmsr.id = acn.record
WHERE ahr.pickup_lib = *org_unit id*
AND ahr.capture_time IS NULL
AND ahr.cancel_time IS NULL
AND ahr.fulfillment_time IS NULL
AND ahr.frozen = FALSE
AND date(ahr.request_time) < '2018-09-01'
AND ahr.id NOT IN (SELECT hold FROM action.hold_copy_map WHERE target_copy
IN (SELECT id FROM asset.copy WHERE status = 9 AND circ_lib = *org_unit
id*));

I hope that helps!
Jessica
