Applies to: SQL Server (all supported versions)
Returns the content of one or more trace files in tabular form.
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 Events instead.
fn_trace_gettable ( 'filename' , number_files )
Specifies the initial trace file to be read. filename is nvarchar(256), with no default.
Specifies the number of rollover files to be read. This number includes the initial file specified in filename. number_files is an int.
If number_files is specified as default, fn_trace_gettable reads all rollover files until it reaches the end of the trace. fn_trace_gettable returns a table with all the columns valid for the specified trace. For more information, see sp_trace_setevent (Transact-SQL).
Be aware that the fn_trace_gettable function will not load rollover files (when this option is specified by using the number_files argument) where the original trace file name ends with an underscore and a numeric value. (This does not apply to the underscore and number that are automatically appended when a file rolls over.) As a workaround, you can rename the trace files to remove the underscores in the original file name. For example, if the original file is named Trace_Oct_5.trc and the rollover file is named Trace_Oct_5_1.trc, you can rename the files to TraceOct5.trc and TraceOct5_1.trc.
This function can read a trace that is still active on the instance on which it is executed.
Requires ALTER TRACE permission on the server.
A. Using fn_trace_gettable to import rows from a trace file
The following example calls
fn_trace_gettable inside the
FROM clause of a
USE AdventureWorks2012; GO SELECT * INTO temp_trc FROM fn_trace_gettable('c:\temp\mytrace.trc', default); GO
B. Using fn_trace_gettable to return a table with an IDENTITY column that can be loaded into a SQL Server table
The following example calls the function as part of a
SELECT...INTO statement and returns a table with an
IDENTITY column that can be loaded into the table
USE AdventureWorks2012; GO SELECT IDENTITY(int, 1, 1) AS RowNumber, * INTO temp_trc FROM fn_trace_gettable('c:\temp\mytrace.trc', default); GO
