I didn't say it'd be easy. :)

It didn't terminate it, though I agree that it would have been nice if I
could control if it would terminate on first warning or not.

Yes, rather frustrating even with only 20k rows.

It'd be nice to be able to do what (I believe..) Oracle and Access can
do- dump the warnings/error messages/rows into a seperate table and go
over them afterwards.. Probably wouldn't have helped me in this case
but I've been in other situations where it would have been nice. :)
