sys.sysprocesses (Transact-SQL)
Applies to: √ SQL Server (all supported versions)
Contains information about processes that are running on an instance of SQL Server. These processes can be client processes or system processes. To access sysprocesses, you must be in the master database context, or you must use the master.dbo.sysprocesses three-part name.
important
This SQL Server 2000 system table is included as a view for backward compatibility. We recommend that you use the current SQL Server system views instead. To find the equivalent system view or views, see Mapping System Tables to System Views (Transact-SQL). This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
See sys.sysprocesses.
