Use LEFT JOIN from orderdetail to the despatch tables.

select 	od.*, isnull(dd.despqty, 0) as despqty, (od.ordqty - isnull(dd.despqty, 0))  as pendingqty
from	orderdetail od 
	left join 
	(	despatch dp inner join despatchdetail dd
		on	dp.despatchid	= dd.despatchid
	)
	on	od.orderid	= dp.orderid
	and	od.prodid	= dd.prodid
where	od.ordqty	<> isnull(dd.despqty, 0)
