No. I was submitting a request that we could add LIMIT to DELETE FROM. There are work arounds for this. But it would be nice to skip the work arounds.

Nick,
Are you confirming that DELETE FROM - LIMIT is working?
Thanks,

// It would be nice if the DELETE FROM supported LIMIT. I can already feel the dislike for this post coming back in my direction.
// I have had numerous times over the years where I need to delete a lot of rows from a table but because each row is linked to so many other tables it will cause // a problem in performance if I don’t limit the size of the deletion.
I use a query like this to accomplish a limited deletion –
Delete from table1 where table1.id in (select table1.id from table1 limit yourlimitnumber)
