Which release of MySQL are you using?

Version 5.5.45-cll

How many rows do you get if you remove the GROUP_CONCAT operator? We don't need to see the results. (sometimes it is a good idea to look at the raw, unprocessed results)

Is it possible that you are attempting to concat more values than allowed by --group-concat-max-len ?

When I did this I realized I was missing a GROUP BY clause

Her is the debugged working version. Thanks guys.

SELECT
ht.*,
CONCAT(o.first_name, " ", o.last_name) AS orphan,
GROUP_CONCAT(DISTINCT hti.rec_code ORDER BY hti.rec_code ASC SEPARATOR ", ") AS alloc
FROM hiv_transactions ht
LEFT JOIN tk_orphans o ON ht.orphan_id = o.orphan_id
LEFT JOIN hiv_trans_items hti ON ht.transaction_id = hti.hiv_transaction_id
WHERE ht.donor_id = 730 AND ht.tr_date BETWEEN "2015-01-01 00:00:00" AND "2015-12-31 23:59:59"
GROUP BY ht.`transaction_id`
ORDER BY ht.tr_date DESC, ht.rec_code ASC;
