If a table is created with a Primary key, a clustered index will be created automatically. We cannot drop a clustered index through T-script but we can drop through Object explorer(Table–>Indexes–>Right click on index and click on delete). It will delete both Primary key and clustered index and that table will be converted to Heap table since that table has no clustered index. We can access a Heap table.

Perfect !!! Loved to learn this and another true facts there is no ENABLE OPTION you can only REBUILD or DROP and CREATE the index.

This is not the case with non clustered indexes.

Thanks for sharing the update, in general, if we have heap table in database so it doesn’t contain any dependency with indexes. It does work faster in bulk operation.
