Returns a row for each query processor job that is scheduled for asynchronous (background) execution.
NOTE!! To call this from Azure Synapse Analytics (SQL Data Warehouse) or Parallel Data Warehouse, use the name sys.dm_pdw_nodes_exec_background_job_queue.

|pdw_node_id||int||Applies to: Azure Synapse Analytics (SQL Data Warehouse), Parallel Data Warehouse
The identifier for the node that this distribution is on.
On SQL Server, requires
VIEW SERVER STATE permission.
On SQL Database Premium Tiers, requires the
VIEW DATABASE STATE permission in the database. On SQL Database Standard and Basic Tiers, requires the Server admin or an Azure Active Directory admin account.
This view returns information only for asynchronous update statistics jobs. For more information about asynchronous update statistics, see Statistics.
The values of object_id1 through object_id4 depend on the type of the job request. The following table summarizes the meaning of these columns for the different job types.

The following example returns the number of active asynchronous jobs in the background queue for each database in the instance of SQL Server.
SELECT DB_NAME(database_id) AS [Database], COUNT(*) AS [Active Async Jobs] FROM sys.dm_exec_background_job_queue WHERE in_progress = 1 GROUP BY database_id; GO
