How many distinct orders were there in 2003 when the quantity ordered was less than 30?
year(orderDate) = '2003'; quantityOrdered < 30;
SELECT COUNT(DISTINCT T1.orderNumber) FROM orderdetails AS T1 INNER JOIN orders AS T2 ON T1.orderNumber = T2.orderNumber WHERE T1.quantityOrdered < 30 AND STRFTIME('%Y', T2.orderDate) = '2003'
