Hey Raj,

Ever paranoid of a ruse I had to see for myself that your query worked on O9i and not O8i. I cranked up my O9i test server and confirmed it does indeed work on 9i and not 8i. (See below.) I'm still looking for a way to get this to work on O8i. In the meantime I'll submit a TAR but I hate it when the "solution" is to upgrade to the next version.

SELECT *
