SQL and case structure
Listers: I've used SAS's version of SQL and it allows the coding of conditional logic in the SELECT statement: proc sql; select acct_no, case substr(acct_no,16,1) when '1' then 'one' when '2' then 'two' else 'other' end as desc from star.kills; quit; The same syntax does not work in SQL*Plus for Oracle 8.

RE: internal date value
Thomas:
I'm a SAS guy who must pull Oracle data from the back-end DB.
SAS stores dates internally as elapsed days since Jan 1, 1960. If I request
an Oracle date field, SAS creates a datetime variable, number of seconds
since midnight Jan 1, 1960. Rather than use SAS functions to extract the
date ( e.g. datepart function ), I'd like to push that back to Oracle if
possible and create a simple date field on SAS. I can accomplish the
desired effect with:
select date_fld - to_date('01Jan1960','ddmon') as sas_date
but I was hoping there was an Oracle function to surface the internal value
( appears to be days since Jan 1, 1968 ). Presumably such a function would
be more efficient.
Thanks for your help.

RE: internal date value
Thomas:
I'm aware of the to_char function and the various options. However as you
alluded to, that lands in SAS as a character literal, e.g. '22/01/2004'
requiring me to convert it to internal format before I can use it in SAS.
I think I have to use my work around:
select date_fld - to_date('01Jan1960','ddmon') as sas_date
Thanks for your time and help.

Harry,
Look at the to_char function in Oracle. It will convert a date field to
*any* format you want.
for example:
select to_char(date_field,'mm/dd/ hh24miss') will return a date in the
format as noted. You have about as many options as you probably need. You
can combine as many format and functions as you think you need.
to_char translates dates to chars and to_date does the opposite - but both
use the same format statements.
This should work fine for you.
And for you info - Oracle dates are stored internally based on a date going
back many centuries - not just to 1968!
Good Luck

Is there something built into Oracle to give me this internal format?
