I have two tables

ITEMS : id, name

CATEGORIES: items_id, category

I need to select all the items whose IDs are NOT in the CATEGORIES table.

I suspect it’s really simple, but can’t figure out the syntax.

    NOT IN (select CATEGORIES.item_id)

    not sure if that’s faster than the join above… but it works.
