Script to find out Heap Table/Table without clustered Index

1 Reply

Heap Table: Table without a clustered index is called Heap Table. You can find out the Heap Table by querying the sys.indexes or sys.partitions against the index_id column.

select OBJECT_NAME(object_id),* 
from sys.indexes where index_id = 0

Select OBJECT_NAME(object_id),*  
from sys.partitions where index_id = 0
