Dana,
if you have page level locking, you can easily
get a deadlock from an atomic insert done as
a single transaction, and another user doing
an atomic select in another single transaction.
It happens this way:

insert recordselect record from second
, of course, whether this is workable. And,
yes, from a design point of view it IS ugly.

a deadlock can easily occur on a single table with row-level (or page-level)
locking. What happens is something like the following:
connectionhas lock on
ffense intended,
as I say, I may be totally off the beam here.
