Yes, I did, it won't do the job for us. I didn't explain the whole
usecase: we are dealing with a 50-billion row table which we want
to split into 1-million-row tables, and then dynamically break each
of these into smaller pieces in order to speed up n^2 near-neighbor
joins. If we
Hi,
Is there a way to dynamically split a big table
into n smaller tables by doing a single scan of
the table that is being split? Here is more

alter table large_table add ID int unsigned
