Gavin,

i couldn't find a way to do session.delete for a list of primarykeys.

i wanted to say "delete from mytable where pk in (:mylist)"

i can do in queries with criteria,using Expression.in, however since session.delete requires a select query string, i couldn't fit my criteria into that.

are there any plans to implement session.delete for a collection?

i had to loop for now, but this is not acceptable, because i could be deleting hundreds at a time.

if i missed something , please let me know. maybe there is already a way to do this.

thanks.

No. We have discussed mass deletes a number of times, search the mailing list and forum archives. It turns out that implementing mass deletes in ORM is signifantly more difficult than it sounds. Its difficult (impossible?) to guarantee some of our semantics.
