Returns a row for each query processor job that is scheduled for asynchronous (background) execution.
NOTE!! To call this from Azure SQL Data Warehouse or Parallel Data Warehouse, use the name sys.dm_pdw_nodes_exec_background_job_queue.
|Column name||Data type||Description|
|time_queued||datetime||Time when the job was added to the queue.|
|database_id||int||Database on which the job is to execute.|
|object_id1||int||Value depends on the job type. For more information, see the Remarks section.|
|object_id2||int||Value depends on the job type. For more information, see the Remarks section.|
|object_id3||int||Value depends on the job type. For more information, see the Remarks section.|
|object_id4||int||Value depends on the job type. For more information, see the Remarks section.|
|error_code||int||Error code if the job reinserted due to failure. NULL if suspended, not picked up, or completed.|
|request_type||smallint||Type of the job request.|
|retry_count||smallint||Number of times the job was picked from the queue and reinserted because of lack of resources or other reasons.|
|in_progress||smallint||Indicates whether the job has started execution.|
1 = Started
0 = Still waiting
|pdw_node_id||int||Applies to: Azure 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 the server.
On SQL Database Premium Tiers requires the VIEW DATABASE STATE permission in the database. On SQL Database Standard and Basic Tiers requires the SQL Database 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
