Hi,
I am observing a strange behaviour with SQL server.
When i fire a query on SQL 2005
SELECT TOP 5000 * FROM ::fn_trace_gettable
'C:\traces\TraceFile50MB\tracefile_1.trc', 1) WHERE starttime >
'2008-04-22 11:21:22.05'
it takes a few milliseconds to execute, but when i change the '>' sign to
'<' in the where clause sign it takes more than 7 seconds. To be more precise
the new query would become
SELECT TOP 5000 * FROM ::fn_trace_gettable
'C:\traces\TraceFile50MB\tracefile_1.trc', 1) WHERE starttime <
'2008-04-22 11:21:22.05'
I have seen this behaviour in almost all my trace files.
Please let me know as to how this query can be optimized and why is this
taking so much time.
.
