I read Mark
What I was asking why if the view has the same name from one release to other
the number of fields change
"but your query in 9i don't work, can't find ds.end_buf#" means "why things like things happens."
Sorry If I didn't express correctly

Why you say this
I'll refrain from comment on the article referenced by that URL, except to say that I don't have much faith in the author's knowledge of Oracle."

Personally in new topics, my two main source of knowledge are Kyte and Burleson.

Juan,

Did you read my previous posting?

In particular, the part where I said "I've figured out how to do this in 8i, but in 9i, I have not succeeded in writing such a query. I spent some time running in circles a few weeks ago, and never did get anywhere."

And then I detailed how my query works for 8i ONLY, and asked if anyone had worked it out for 9i........
