Applies to: SQL Server (all supported versions) Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Parallel Data Warehouse
Returns a row for each query processor job that is scheduled for asynchronous (background) execution.
To call this from Azure Synapse Analytics or Parallel Data Warehouse, use the name
sys.dm_pdw_nodes_exec_background_job_queue. This syntax is not supported by serverless SQL pool in Azure Synapse Analytics.

|pdw_node_id||int||Applies to: Azure Synapse Analytics, Parallel Data Warehouse
The identifier for the node that this distribution is on.
On SQL Server 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 or the Azure Active Directory admin account is required. On all other SQL Database service objectives, the
VIEW DATABASE STATE permission is required in the database.
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.
|Asynchronous update statistics||Table or view ID||Statistics ID||Not used||Not used|
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
