Re: an already existing alter table drop column ?!?!?!

I do like the flag idea as a temporary patch until a fully workable solution
is available.  Just run a delete on the column and then flag it so it takes
up no space and is hidden.  By doing this now a more perfect solution can be
found later.

too many dissending opinions on how it should (and shouldn't) be done ...
the one that was put in pre-maturely needed 2x the disk space to do ... so
if you had a multi-gig table, you had to have enough free space to store a
second copy in order to remove a column ...

there was a bunch of us that felt that it could be done better using a
'flag' on the column so that it was hidden ... and some that thought ...
etc, etc ...
