234 MB with only 400 rows? Sure it's not 234 kb? How many pages does the index (not the table) have?

Ok. But can you explain me why the avg_percent_in_fragmentation is not getting reduced for this scenario. For the same column if I create a clustered index in stead of non clustered index, I dont find any fragmentation.

Hi Gail,
Sorry. It is 234KB. I typed wrongly.

Your index is less than 1 extent (8 pages) in size. There's no point in rebuilding that and, considering the way SQL allocates pages for very very small indexes, rebuilding it won't change the fragmentation anyway.
