I don't think anyone will want to type in a full SQL query.
However, I can show you the way:
SELECT ost_thread_entry.title AS Subject FROM ost_ticket JOIN ost_thread ON ost_ticket.ticket_id = ost_thread.object_id JOIN ost_thread_entry ON ost_thread.id = ost_thread_entry.thread_id WHERE ost_ticket.ticket_id = 1;
This query joins the three tables based on their respective IDs and filters the results where the ticket_id is 1 in the ost_ticket table. The title column from the ost_thread_entry table is then selected.
