Among other questions, this one asked how to delete from a join.
My question: How much of this is standard SQL? On which databases would this actually work (most notably for me would be Oracle, MySQL and SQLServer)?

DELETE … FROM .. Is not part of the ANSI standards, nor UPDATE … FROM … for that matter. This includes any join syntax, since the join can only be specified with a FROM.
All vendors implement this though in one form or another.
