I think he may have been dumping into a new table thus no results message
though I thought inserts stated the number of records created, but can't
recall if a select .. into bulk load does or not.

which is pretty slow.

Simon is that correct that you were dumping into a new table?
I assumed you got something if you said it works correctly now.
