Fractions of seconds in NLS_DATE_FORMAT

Question

Hi all,
Does anyone know what the date mask is to have hundredths of seconds? I've been trolling around the
net but I can't seem to find a list of valid masks.
I need to compare date/time values in Oracle with those in another database where the fractions are stored as .nnn
At present I've got NLS_DATE_FORMAT set as 'ALTER SESSION SET NLS_DATE_FORMAT=''YYYY-MM-DD HH24:MI:SS''';
What I really need is something the lines of
'ALTER SESSION SET NLS_DATE_FORMAT=''YYYY-MM-DD HH24:MI:SS.FFF''' ;
where FFF is the fractions.
I would even be happy to have the fractions all come out as .000
Is this possible?
Thanks
Dave

hi,
that all works fine using your example but... I'm extracting from v$logmnr_contents which is created by the logminer application.
This view contains a field called SQL_REDO which may or may not contain any date/time columns. e.g.
"delete from ARCH_RCPT_MAST where RCPT_NO = '45510' and CREATE_DT = TO_DATE('2008-01-10 09:25:13', 'YYYY-MM-DD HH24:MI:SS') and USER_NAME = 'MARKL' and STATUS = 'POST' and STATUS_DT = TO_DATE('2008-01-10 11:17:41', 'YYYY-MM-DD HH24:MI:SS') and INV_STATUS IS NULL and RECV_LOC = 'IN' and RECV_DOCK = '1' and PTWY_RULE = 'DEFAULT' and INSP IS NULL and LOCATION IS NULL and TRAILER_NO IS NULL and BOL_NO IS NULL and AUX_1 = ' 45510' and AUX_2 = '193455' and AUX_3 IS NULL and AUX_4 IS NULL and AUX_5 IS NULL and AUX_6 IS NULL and AUX_7 IS NULL and AUX_8 IS NULL and AUX_9 IS NULL and AUX_10 IS NULL and UPLD = 'Y' and UPLD_DT IS NULL and UPLD_CNT IS NULL and CARRIER IS NULL and CHKIN_RULE IS NULL and CLOSE_DT = TO_DATE('2008-01-10 11:17:41', 'YYYY-MM-DD HH24:MI:SS') and WHO_CLOSE = 'GG' and POST_DT = TO_DATE('2008-01-10 11:17:41', 'YYYY-MM-DD HH24:MI:SS') and WHO_POST = 'GG' and FIRST_TRANS = '8659969' and LAST_TRANS = '8659969' and WHO_CREATE = 'MARKL' ";
This string needs converting to ANSI SQL so it can put pushed into a SQL server database so all I can really do is parse out the Oracle functions such as TO_DATE etc
I have a trigger on the login which forces the date data in the coulmn SQL_REDO to come out as YYYY-MM-DD HH24:MI:SS
Unless I'm missing something I don't see how I can use to_timestsamp functions on a large char column such as this.
