sys.trace_subclass_values (Transact-SQL)
The sys.trace_subclass_values catalog view contains a list of named column values. These subclass values do not change for a given version of the SQL Server Database Engine.
For a complete list of supported trace events, see SQL Server Event Class Reference.
Important
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. Use Extended Event catalog views instead.
