Hi Experts i would be rebuilding the index inoder to get rid of framentation .
Im bit worried about the fill factor , non-clustered indexes, primary key and foreign key, any dependency with other table. Iam enclosing the query for your reference, i need to understand how to take care for fill factor or non clustered indexes and any other dependency , is it taken care by sql engine or by default it will take the fill factor which already exist.

what do you mean by
is it taken care by sql engine or by default it will take the fill factor which already exist ?

if you don't specify a new fill factor, sql server will use the one that is already defined

depends on how you are going to rebuild but you can specify it in the rebuild command (if you use  DBCC DBREINDEX  for example)

If you have the luxury of time, you could drop and recreate your indexes. Also, one other thing to consider is total fragmentation on the database. A solution is to download contig.exe from sysinternal.com. Its a free download from M$ and  allows you to make contiguous a file.
