CASE has been around since at least 8.1.6. The syntax you posted is incorrect. I believe you wanted something akin to the following:

  1 select case
  2 when 1=1 then 2
  3 else 3
  4 end "1"
  5* from dual
SQL> /         1

I'm doing some research for a book, and I need to know when Oracle began to support CASE expressions. I thought it was in Oracle9i, but the new features list seems to imply that CASE may have come about in 8.1.7. Can anyone with 8.1.7 verify this for me? I have 8.1.6 and 9.whatever, but not 8.1.7 or I'd try it myself.

If you have 8.1.7, and have a second to experiment, try the following query as a test:

SELECT CASE 1 WHEN 1 THEN 2
FROM dual;
