I have a database that shows a few tables as HEAP, even since I am sure all of them have Clustered indexes and some even have a few Non-Clustered indexes, since a long time ago.
my understanding for HEAP table is : "A heap is a table without a clustered index"
as seen in the image, this tables have a clustered index
Currently using SQL Server 2014 with Compatibility mode 120
then , why are this tables being shown as heap when they have a clustered index ?
Thanks!
