I guess that is just a visual problem because I no longer recall an
example problem. Maybe it was a problem when selecting fields with the
same name in different tables.

I don't recall what the problem was, but I tried to declare a server
but I could not figure how to execute it and have it return a result set
to PHP. Maybe
it was a PHP limitation when dealing with the OCI API.

No. I even don't know if PHP could do that.

Actually I had a hard time to deal with Oracle (as most people) because
I developed a PHP database abstraction named Metabase that among many
other things has the ability to let the developers to specify a range of
rows that are returned by a select query.
Metabase works with many different databases and it supports query
result row range clipping in all of them. In those that something like
the LIMIT clause is not supported like with Oracle, the feature is
emulated trasparently with client side row skipping. It's not very
efficient but it allows you to write portable applications.
Maybe later I find a more efficient way to do it without compromising
the portability Metabase developers applications. I think there is a way
to do it with Oracle extensions, but I need to try it first to tell if
If you want to know more about Metabase, you may donwload it for free
