i am looking for a sql statment that I run in VBA to get the record from my highest number from a column:
example :
WorkOrderNumber --------------StationID---------------------SequenceNumber
wrk123                                       LAB1                                 1
wrk123                                       LAB2                                 2
wrk123                                       LAB6                                 3

I would like the record from line 3 in my example
here is currently my SQL statment :

strsql = " select STATIONID,TECHID from SVC06100 where WORKORDNUM = '" & StrWORTVNum.Value & "' AND LNITMSEQ is the highest number"


thank you

try
"select STATIONID,TECHID from SVC06100 A where WORKORDNUM = '" & StrWORTVNum.Value & "'" &
" AND STATIONID = select(stationid, max(LNITMSEQ) from SVC06100 B 
                       where B.stationid = A.stationid group by stationid)"

I am sorry , I am trying to understand the code and I am not sure why we have STATIONID =......

just to be clear i only want the value of STATIONID, TECHID for the LINITMSEQ that has the highest number.

Its using a subquery to determine the stationid of the record with the highest LINITMSEQ
The first one has an error, change it to
"select STATIONID,TECHID from SVC06100 A where WORKORDNUM = '" & StrWORTVNum.Value & "' AND STATIONID = (select stationid, max(LNITMSEQ) from SVC06100 B where B.stationid = A.stationid group by stationid)"

Why not just try:
"SELECT TOP 1 StationID, TechID FROM FROM Svc06100 WHERE WorkOrdNum = '" & StrWORTTVNum.Value & "' ORDER BY LNITMSEQ DESC"

Sorry, my mistake
"select STATIONID,TECHID from SVC06100 A where WORKORDNUM = '" & StrWORTVNum.Value & "' AND LNITMSEQ = (select  max(LNITMSEQ) from SVC06100 B where B.stationid = A.stationid group by stationid)"

Well, I tried Carl suggestion and it did work perfectly  . Ewangoya, I am still not sure why you want me to group by stationID . But thanks for your help anyway.
