SQL Server DBCC Commands: DBCC TRACESTATUS

DBCC TRACESTATUS is a database console command (DBCC) in Microsoft SQL Server that can be used to display the status of a trace flag, which is a special setting that can be used to enable or disable specific behaviors in the database engine. Trace flags can be useful for troubleshooting issues or for testing the effects of different behaviors on query performance.

To use DBCC TRACESTATUS, you must specify the trace flag number you want to display the status for. You can also specify the trace flag number as a hexadecimal value, preceded by a “0x”.

Here is an example of how to use DBCC TRACESTATUS to display the status of trace flag 1222:

-- Display the status of trace flag 1222
DBCC TRACESTATUS (1222);

The output of DBCC TRACESTATUS will be a message indicating whether the trace flag is enabled or disabled, and whether it is a global trace flag or a session trace flag. If the trace flag is not recognized, the message “DBCC execution completed. If DBCC printed error messages, contact your system administrator.” will be displayed.

It is important to note that DBCC TRACESTATUS only displays the status of a trace flag. It does not allow you to enable or disable trace flags. To enable or disable trace flags, you can use the DBCC TRACEON and DBCC TRACEOFF commands.

DBCC TRACESTATUS is a useful tool for displaying the status of trace flags in SQL Server, but it should be used with caution.
