Fetch last record from duplicate values

Hi, i have a sql table where there is no primary key defined on the key field (123 below) as it contains duplicates. From the below sample data if i need to know which is the last updated record what should i do ? In Foxpro the below is achieved using the scan() function.. pls help me with the query in VB as i have been struggling since long to get this up working.


Num Delvd Date Time Delay reason Entry_date Time

123 2002-09-03 0600 CUSTOM HELD NULL 2002-09-03 1209

How about something like...

SELECT * FROM <TABLE> ORDER BY <FIELDS>

SET RS = DB.OPENRECORDSET...

IF RS.RECORDCOUTN > 0 THEN
RS.MOVELAST
ENDIF
