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

  This dynamic management view is used internally by [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] to do the following:  
  
-   Keep track of debug data such as outstanding allocations.  
  
-   Assume or validate logic that is used by [!INCLUDE[ssNoVersion](../../includes/ssnoversion-md.md)] components in places where the component assumes that a certain call has been made.  
  
|Column name|Data type|Description|  
|-----------------|---------------|-----------------|  
|**stack_address**|**varbinary(8)**|Unique address for this stack allocation. Is not nullable.|  
|**frame_index**|**int**|Each line represents a function call that, when sorted in ascending order by frame index for a particular **stack_address**, returns the full call stack. Is not nullable.|  
|**frame_address**|**varbinary(8)**|Address of the function call. Is not nullable.|  
  
## Remarks  
 **sys.dm_os_stacks** requires that the symbols of the server and other components be present on the server to display the information correctly.  
  
## Permissions  
On [!INCLUDE[ssNoVersion_md](../../includes/ssnoversion-md.md)], requires `VIEW SERVER STATE` permission.   
On [!INCLUDE[ssSDS_md](../../includes/sssds-md.md)] Premium Tiers, requires the `VIEW DATABASE STATE` permission in the database. On [!INCLUDE[ssSDS_md](../../includes/sssds-md.md)] Standard and Basic Tiers, requires the  **Server admin** or an **Azure Active Directory admin** account.
