Hi _Helen_,
From: "Helen Borrie" <helebor@...>
:-)
Yes, I observed the confusion I've made ! Sorry ! It was Ann !
I'm new to the list and untill I'll get acustomed with the persons ...
But I presented just an option in this case. Jason is the one who needs to
choose between the options ! Imagine a case when the "very-large-table" is
referenced by a foreign key and one cannot delete those rows at all, or when
one needs them for historycal purposes. And, apropos, if those rows have
such a short life, why to put them in a database, anyway (you can take this
as a joke, but in some cases it may be a question to be asked ;-) ?
Raul.
