That will not work for me.

Since the user can navigate through the entries in the list before pressing
<C-Right>, I need to get the currently selected item before I redisplay the
popup with different values (based on what was highlighted).

So after a issue a <C-Y> on behalf of the user, I setup the SQL completion
plugin for the next step and trigger omni again using the new feedkeys()
function. According to the docs feedkeys() will executes the keys once the
function completes.
So as I was typing this up I just realized I can code this as follows:
function! sqlcomplete#DrillIntoTable()
if pumvisible()
call sqlcomplete#Map('column')
call feedkeys("\<C-Y>\<C-X>\<C-O>")
else
exec "normal! \<C-Right>"
endif
return ""
Endfunction
Since I technically do not need to hit the <C-Y> prior to calling into
sqlcomplete#Map. So the code works as is, and avoids the crash.
But for future developers, I could see a need to be able to retrieve the
currently selected item in the popup, so the question stands although it is
moved way down my priority list.
Thanks for the response Benji, and leading me in the right direction.
