On MySQL, this does not run:
delete from robottinosino where date = (select max(date) from robottinosino);
Error message:
ERROR 1093 (HY000): You can’t specify target table ‘robottinosino’ for
update in FROM clause
Question:
MySQL doesn’t allow you to delete from a table that you’re also selecting from. It’s a race condition in many cases – you could be deleting records from the table before the select part of the query has had a chance to retrieve them.
In your case, the query should be allowed, because there isn’t any danger of this race, but MySQL isn’t smart enough to figure that out.
There’re a workarounds here: MySQL Error 1093 – Can't specify target table for update in FROM clause
