-1

Result Sets

The following table describes the information in the result set.

Column name	Description
TraceFlag	Name of trace flag
Status	Indicates whether the trace flag is set ON of OFF, either globally or for the session. 1 = ON 0 = OFF
Global	Indicates whether the trace flag is set globally 1 = True 0 = False
Session	Indicates whether the trace flag is set for the session 1 = True 0 = False

DBCC TRACESTATUS returns a column for the trace flag number and a column for the status. This indicates whether the trace flag is ON (1) or OFF (0). The column heading for the trace flag number is either Global Trace Flag or Session Trace Flag, depending on whether you are checking the status for a global or a session trace flag.

Remarks

In SQL Server, there are two types of trace flags: session and global. Session trace flags are active for a connection and are visible only for that connection. Global trace flags are set at the server level and are visible to every connection on the server.
