Does anyone know if I can add a hint SQL_BUFFER_RESULT to INSERT .. SELECT ON
DUPLICATE
ex..
INSERT INTO foo
SELECT SQL_BUFFER_RESULT* FROM bar

bar as soon as possible by moving

That's what it does.
Why can't it do this?

I thought if MySQL found a duplicate key on the insert, it would

Is there a way to get Insert ... select ... On Duplicate Update to
update the row with the duplicate key? Otherwise I'll have to use Replace
which is inefficient because it deletes the old duplicated row and then
inserts the new row with the same key. I'd much rather have it update
Thanks Shawn, Sergei.
I'll get onto the new version as soon as I can.
Tom.

(and there're some problems with name resolution there, so better wait
for 4.1.11 - search bugdb for details)

I would find it very useful if you *could* do this. I know it would be
complicate how you would handle the syntax for what to do when you hit
a duplicate key, could do this: update all the columns that are *not*
