You can do something like the following, where SEQ is the keyed sequence # you said you had.
With t1 as( select max(SEQ) as MSEQ from file1 group by RCDID)
Select FILE1.*
from FILE1
Join T1 on T1.MSEQ=FILE1.SEQ

Subject: SQL to add records based on latest record id
CAUTION: This email originated from outside of the organization. Do not click links or open attachments unless you recognize the sender and know the content is safe.
I have a journal file extracted with EXPJRNE tool. I exported to a table called JRNHDR.
I need to copy JRNHDR back to the production data for certain record id's.
The file is keyed by a sequential number. So I need to grab the last record for each record id.
Typically there is a PT, UB, and UP for each record id, but there can be multiple UB/UP pairs. I need the last one.
Is there a SQL statement that can grab the only the last record id? I have date & time in the EXPJRNE created file but time isn't specific enough.
Thanks, Art
