Just a quick follow-up. The query I provided for use as a test contained a syntax error. I omitted the END keyword. I'm hanging my head in shame. The query should have been:

SELECT CASE 1 WHEN 1 THEN 2 END
FROM DUAL; Note that Oracle9i not only supports the above, but also:

SELECT CASE WHEN 1=1 THEN 2 END
FROM DUAL;

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;
