Your inner select is returning just 20130607...

which makes the outer statement look like:
SELECT TISEQ FROM tapeinv00 WHERE titapedate = 20130607...

So it's obvious why two rows are being returned...

You need to be more specific in your outer where:
SELECT TISEQ
FROM tapeinv00
WHERE tisystem = 'RG'
and TIlabel = 'FRIDAY'
and tilocate = 'VAULT'
and
titapedate = (select

max(titapedate)

from tapeinv00

where tisystem = 'RG'

and TIlabel =

'FRIDAY'

and tilocate = 'VAULT' )

I have a table with the following
TISYSTEM TILABEL TILOCATE TISEQ TITAPEDATE
RG FRIDAY VAULT 1 20,130,614
RG FRIDAY VAULT 2 20,130,524
RG FRIDAY VAULT 3 20,130,531
RG FRIDAY VAULT 4 20,130,607
RG MONDAY VAULT 1 20,130,614
RG MONDAY VAULT 2 20,130,524
RG MONDAY VAULT 3 20,130,531
RG MONDAY VAULT 4 20,130,607

I am trying to get the value of TISEQ for the record with the highest
date for a specific system, label, location

So I have the following query and it works fairly well, except I seem
to get two records back

SELECT TISEQ FROM tapeinv00 WHERE titapedate = (select
max(titapedate) from tapeinv00 where tisystem = 'RG' and TIlabel =
'FRIDAY' and tilocate = 'VAULT' )

What I would hope to get for this query is 1 I get two records with 1
returned and I'm not sure why.
Ideas?
Better way to do this query?

Thanks

Mike
