SELECT *
FROM tbl_order_head AS o
INNER JOIN tbl_orders_log AS c
ON o.PAYMENT_TRANSACTION_LOG_ID=c.TRANSACTION_ID
WHERE o.VISUAL_ID = '77783';

tbl_order_head 67,000 (30 fields) records, tbl_orders_log 17000 (5 fields) records. I don't know if it would eventually return as I am running it on a live server and fear overloading.

I am doing similar queries and much more complex queries successfully.
