SQL Server 2008 :: Logic To Rebuild Only Clustered Indexes / Skipping To Rebuild Non Clustered Indexes In Same Table

I have a requirement to only rebuild the Clustered Indexes in the table ignoring the non clustered indexes as those are taken care of by the Clustered indexes.

In order to do that, I have taken the records based on the fragmentation %.

But unable to come up with a logic to only consider rebuilding the clustered indexes in the table.

create table #fragmentation
(
FragIndexId BigInt Identity(1,1),
--IDENTITY(int, 1, 1) AS FragIndexId,
DBNAME nvarchar(4000),
TableName nvarchar(4000),

[Code] ....
