Answer 1

SELECT c.customerId, c.fullName, c.sex, t.Id AS transId, t.bookingDate
    FROM customer c
        INNER JOIN (SELECT customer, MAX(bookingDate) AS MaxDate
                        FROM transaction
                        GROUP BY customer) q
            ON c.customerId = q.customer
        INNER JOIN transaction t
            ON q.customer = t.customer
                 AND q.MaxDate = t.bookingDate;
