# sys.hash_indexes (Transact-SQL)
[!INCLUDE[tsql-appliesto-ss2008-xxxx-xxxx-xxx-md](../../includes/tsql-appliesto-ss2008-xxxx-xxxx-xxx-md.md)]

  Shows the current hash indexes and the hash index properties. Hash indexes are supported only on [In-Memory OLTP (In-Memory Optimization)](../../relational-databases/in-memory-oltp/in-memory-oltp-in-memory-optimization.md).  
  
 The sys.hash_indexes view contains the same columns as the sys.indexes view and an additional column named **bucket_count**. For more information about the other columns in the sys.hash_indexes view, see [sys.indexes (Transact-SQL)](../../relational-databases/system-catalog-views/sys-indexes-transact-sql.md).  
  
|Column name|Data type|Description|  
|-----------------|---------------|-----------------|  
|**\<inherited columns>**||Inherits columns from [sys.indexes &#40;Transact-SQL&#41;](../../relational-databases/system-catalog-views/sys-indexes-transact-sql.md).|  
|**bucket_count**|**int**|Count of hash buckets for hash indexes.<br /><br /> For more information about the bucket_count value, including guidelines for setting the value, see [CREATE TABLE &#40;Transact-SQL&#41;](../../t-sql/statements/create-table-transact-sql.md).|

     [name] AS 'index_name', [type_desc], [bucket_count]   
FROM sys.hash_indexes   
WHERE OBJECT_NAME([object_id]) = 'T1';
