SQL Server跟踪文件的TextData列为NULL

Question

我使用下面的查询来获取信息，但是，TextData列为空：

select top 10 *
from fn_trace_gettable('d:\data\myTrace.trc', 0)

我还使用SQL Server 2017 Profiler打开跟踪文件，但遇到相同的问题（TextData列为空白。）

这是设置跟踪的查询：

-- Create a Queue
declare @rc int
declare @TraceID int
declare @maxfilesize bigint
declare @traceoptions int
declare @stoptime datetime

set @traceoptions   = 0
set @maxfilesize  =  6
set @stoptime = DATEADD(hh, 1, GETDATE())

-- Create the trace with the name of the output file - .trc extension is     added to filename
exec @rc = sp_trace_create @TraceID output, @traceoptions,     N'D:\data\test924', @maxfilesize, @stoptime
if (@rc != 0) goto error

-- Set the events
declare @on bit
set @on = 1


-- SQL:BatchCompleted events
exec sp_trace_setevent @TraceID, 42, 15, @on
exec sp_trace_setevent @TraceID, 42, 16, @on
exec sp_trace_setevent @TraceID, 42, 1, @on
exec sp_trace_setevent @TraceID, 42, 9, @on
exec sp_trace_setevent @TraceID, 42, 17, @on
exec sp_trace_setevent @TraceID, 42, 6, @on
exec sp_trace_setevent @TraceID, 42, 10, @on
exec sp_trace_setevent @TraceID, 42, 14, @on
exec sp_trace_setevent @TraceID, 42, 18, @on
exec sp_trace_setevent @TraceID, 42, 11, @on
exec sp_trace_setevent @TraceID, 42, 12, @on
exec sp_trace_setevent @TraceID, 42, 13, @on
-- SQL:BatchStarting events
exec sp_trace_setevent @TraceID, 43, 15, @on
exec sp_trace_setevent @TraceID, 43, 16, @on
exec sp_trace_setevent @TraceID, 43, 1, @on
exec sp_trace_setevent @TraceID, 43, 9, @on
exec sp_trace_setevent @TraceID, 43, 17, @on
exec sp_trace_setevent @TraceID, 43, 6, @on
exec sp_trace_setevent @TraceID, 43, 10, @on
exec sp_trace_setevent @TraceID, 43, 14, @on
exec sp_trace_setevent @TraceID, 43, 18, @on
exec sp_trace_setevent @TraceID, 43, 11, @on
exec sp_trace_setevent @TraceID, 43, 12, @on
exec sp_trace_setevent @TraceID, 43, 13, @on

-- Filter out the SQL Profiler events
exec sp_trace_setfilter @TraceID, 1, 0, 6, N'%SaveVerifiedDomains%'
-- exec sp_trace_setfilter @TraceID, 1, 0, 6,     N'%SaveDomainProvisioningRequest%'

-- Set the trace status to start
exec sp_trace_setstatus @TraceID, 1

-- display trace id for future references
select TraceID=@TraceID
goto finish

error: 
select ErrorCode=@rc

finish: 
go
