Quite a straight forward question, by the way: Does merge with append hint causes table fragmentation? ... hah, define fragmentation for me first. when you use append, new rows are added ABOVE the high water mark and no existing free space under the current high water make is used. So the updates would be the only thing using existing free space, all new rows would go above the high water mark.
