-To determine the total number of physically stored deleted rows for a nonclustered columnstore index, add the value in the `deleted_rows` column in `sys.dm_db_column_store_row_group_physical_stats` to the value in the `rows` column in [sys.internal_partitions](../system-catalog-views/sys-internal-partitions-transact-sql.md) for the internal object type `COLUMN_STORE_DELETE_BUFFER` and the same object, index, and partition.

 Compressed row group fragmentation in a columnstore index can be computed using this formula:
 
 ```sql
-100.0 * (ISNULL(total_deleted_rows, 0)) / NULLIF(total_rows, 0)
+100.0 * (ISNULL(total_stored_deleted_rows, 0)) / NULLIF(total_rows, 0)

 > [!TIP]  
 > For both rowstore and columnstore indexes, review index or heap fragmentation and page density after a large number of rows is deleted or updated. For heaps, if there are frequent updates, review fragmentation periodically to avoid proliferation of forwarding records. For more information about heaps, see [Heaps (Tables without Clustered Indexes)](../../relational-databases/indexes/heaps-tables-without-clustered-indexes.md#heap-structures).

 The following example determines the average fragmentation and page density for all rowstore indexes in the current database. It uses the `SAMPLED` mode to return actionable results quickly. For more accurate results, use the `DETAILED` mode. This requires scanning all index pages, and can take a long time.
