Answer / sitaram karancheti
In Oracle:
SELECT COUNT(table1.emp_id), region
FROM table1, table2
WHERE tshirt_size = 3 AND table1.emp_id = Table2.emp_id
AND rownum < 2
GROUP BY region
ORDER BY COUNT(table1.emp_id) DESC
In MySql:
SELECT COUNT(table1.emp_id), region
FROM table1, table2
WHERE tshirt_size = 3 AND table1.emp_id = Table2.emp_id
GROUP BY region
ORDER BY COUNT(table1.emp_id) DESC LIMIT 1
