Thank you but Im still not clear on how the nonclustered index writes the data when Col2 is present vs included.

[@TheSree9120]

If that col2 is in where condition, then can col2 in included would help?

[@raghuoruganti3017]

Dont refer the name as Nonclustered Table when table has only non cluster index. Please term it as HEAP.

[@raghuoruganti3017]

Even Index with included Columns also require some storage space as it is going to append the data of included columns at leaf levels. Please check and confirm

[@aryansena7290]

You are correct.

@@LearnWithMRajput Thanks for the reply.I have been facing some report slowness issue on replication server( On subscriber server end).When I have gone through the execution plan of the query Index scan (non clustered index) costing 83% of the query.I have checked the table index but no clusterd index has been created on the table.Should I suggest to create a cluster index to avoid the slowness issue.Awaiting response.

[@LearnWithMRajput]

Yes definitely..
