[!INCLUDE SQL Server Azure SQL Database Azure SQL Managed Instance]
This dynamic management view is used internally by [!INCLUDEssNoVersion] to do the following:
-
Keep track of debug data such as outstanding allocations.
-
Assume or validate logic that is used by [!INCLUDEssNoVersion] 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. |
sys.dm_os_stacks requires that the symbols of the server and other components be present on the server to display the information correctly.
On [!INCLUDEssNoVersion_md] and SQL Managed Instance, requires VIEW SERVER STATE permission.
On SQL Database Basic, S0, and S1 service objectives, and for databases in elastic pools, the server admin account, the Microsoft Entra admin account, or membership in the ##MS_ServerStateReader## server role is required. On all other SQL Database service objectives, either the VIEW DATABASE STATE permission on the database, or membership in the ##MS_ServerStateReader## server role is required.
