Transact-SQL syntax conventions

Syntax

  
sys.fn_trace_getinfo ( { trace_id | NULL | 0 | DEFAULT } )

Arguments

trace_id
Is the ID of the trace. trace_id is int. Valid inputs are the ID number of a trace, NULL, 0, or DEFAULT. NULL, 0, and DEFAULT are equivalent values in this context. Specify NULL, 0, or DEFAULT to return information for all traces in the instance of SQL Server.

Tables Returned

Column name	Data type	Description
traceid	int	ID of the trace.
property	int	Property of the trace: 1= Trace options. For more information, see @options in sp_trace_create (Transact-SQL). 2 = File name 3 = Max size 4 = Stop time 5 = Current trace status. 0 = stopped. 1 = running.
value	sql_variant	Information about the property of the trace specified.

Remarks

When passed the ID of a specific trace, fn_trace_getinfo returns information about that trace. When passed an invalid ID, this function returns an empty rowset.

fn_trace_getinfo appends a .trc extension to the name of any trace file included in its result set. For information on defining a trace, see sp_trace_create (Transact-SQL). For similar information about trace filters, see sys.fn_trace_getfilterinfo (Transact-SQL).

For a complete example of using trace stored procedures, see Create a Trace (Transact-SQL).

Permissions

Requires ALTER TRACE permission on the server.
