Jonathan,

On 81714 on NT4 we get the following

SQL> select * from v$version;

BANNER

Oracle8i Enterprise Edition Release 8.1.7.1.1 - Production PL/SQL Release 8.1.7.1.0 - Production
CORE 8.1.7.0.0 Production
TNS for 32-bit Windows: Version 8.1.7.1.0 - Production NLSRTL Version 3.4.1.0.0 - Production

SQL>
SQL> SELECT CASE 1 WHEN 1 THEN 2 END
2 FROM DUAL;
SELECT CASE 1 WHEN 1 THEN 2 END
*
ERROR at line 1:
ORA-00923: FROM keyword not found where expected

SQL> SELECT CASE WHEN 1=1 THEN 2 END
2 FROM DUAL; CASEWHEN1=1THEN2END

Under 816 I get the same results as 817. Under 815 neither query works.

For those interested, under Oracle Rdb v7.0-14 both versions of the select case work okay.

Regards,
Bruce Reardon.

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;

Best regards,
