That what I thought! I've been going crazy thinking how it works w/o the rowid! Jeremy

You're tech lead is wrong. Of course it contains the ROWID.

This may seem like a newbie question, but my technical lead told me something yesterday that was contrary my thinking and assumptions on how indexes work.
I was always under the assumption (from studies and readings) that an index contains the values for the indexed columns and a rowid that points back to the table. My technical lead says that indexes do not have a rowid. Is he right? If it doesn't contain the rowid, how does it relate back to the table?
Thanks in advance...
