That's not quite it. - Don't do the 'limit 1'.

I think this will do it. Join to a select statement sorting by timestamp desc - Limit 1 I don't know the name of your timestamp field so I called it theTimeStampfield
create table wrkart.PTIR32501 as (
select drdid#,RCDCUID as userid,date(drstamp) as myDate,sdControl# as control#,drshipper as shipper, sdPieces from drpshp00 inner join whssd00 on drdid#=sddid# inner join (select * from yaudsd order by theTimeStampfield desc limit 1) on audfid = sddid# where drstamp >= '2022-10-26-00.00.00'
and audfnm = 'UPS'
and audds like 'UPS label printed Tracking:%'
)
with data;

Subject: Sql question about join order
I need to get the last record from my inner join table, not the first one.
This query gets the first row from yAudSd. The table has a timestamp. Can I order the join somehow or do I need to create an index?
create table wrkart.PTIR32501 as (
select drdid#,RCDCUID as userid,date(drstamp) as myDate,sdControl# as control#,drshipper as shipper, sdPieces from drpshp00 inner join whssd00 on drdid#=sddid# inner join yaudsd on audfid = sddid# where drstamp >= '2022-10-26-00.00.00'
and audfnm = 'UPS'
and audds like 'UPS label printed Tracking:%'
)
