Based off of a discussion that was posted late last week I've been looking at index fragmentation a bit and I've found that we have some fragmentation on indexes (this database is called by a program and it loads pretty slow...vendor has no idea why so I'm investigating on my own). I've setup a test database and have been rebuilding or reorganizing indexes as needed. However I have one index that is 98% fragmented (gulp)..but I can't find the index anywhere (looking under indexes for the table). I'm guessing that what I'm looking for is the primary key, as when I start to drill down the name of the index comes back as null. Perhaps it's a foreign key? Is it possible to defrag a primary key index and if so how? I don't know if this is really the problem, but I'm having 'fun' looking into this stuff (fairly new to MS SQL and pondering certification).
I've attached a photo of what this looks like...
Thanks in advance.
