SQL can handle character dates in the ISO, USA or EUR format very well, but
not very well with numeric dates.
But there was an enhancement in Release 7.2 in the scalar functions such as
DEC, INTEGER, so a Date, Time or Timestamp can be directly converted into a
numeric date, time, timestamp in the format YYYYMMDD, HHMMSS,
YYYYMMDDHHMMSS)
In this way you only need to convert your character date into a real date
and convert the result into a numeric value:
The following SQL code works on my 7.3 machine:
Dec(Date(CharDate), 8, 0)
Using VarChar_Format might be a little more complicated:
Dec(VarChar_Format(CharDate, 'YYYYMMDD'), 8, 0)

Subject: m/d/yyyy string to yyyymmdd decimal in SQL
My input date, from a spreadsheet that comes from the a client, is a string
using the format (m)m/(d)d/yyyy, (m)m represents that there could be one or
two digits and ditto for (d)d, and I need to convert it to a decimal
yyyymmdd.
The following does it, but it seems to me that there should be an easier
way, utilizing less than four functions to do the conversion. Is there?
select BI_DOSA,
Dec( Replace(
Cast( Date(TIMESTAMP_FORMAT( BI_DOSA, 'MM/DD/YYYY'))
as Char(10)),
'-', ''),8)
from CA8560BIP
BI_DOSA DEC
