I'm programming a method to delete a parent record and all its children in a child table in one go. This is what I have:
UPDATE item i, category_item ci SET i.date_deleted = ?, ci.date_deleted = ? WHERE ci.item_id = i.item_id AND ci.category_id = ?
and it works. But then I realised that I have never used this syntax to delete from two tables simultaneously before.
I would like to know if it is meant to work, or if it is a dirty hack, and whether it is SQL standard, ie. can I use this if I want to run my app on Oracle? (Not that I do but I might want to sell it to people who do)
thanks Adam
