Permissions
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, 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.
Permissions for SQL Server 2022 and later
Requires VIEW SERVER PERFORMANCE STATE permission on the server.

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.
| Request type | object_id1 | object_id2 | object_id3 | object_id4 |
|---|---|---|---|---|
| Asynchronous update statistics | Table or view ID | Statistics ID | Not used | Not used |
Examples
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;
