📄️ Basic Projections
A projection picks the fields you want from a table. Wrap them in { }.
📄️ Nested Projections
A projection key can be more than just a column. It can be a relation walk, an aggregate, or another projection.
📄️ Relation Projections
When you put a relation name inside a projection, ONQL embeds the related rows. The shape of the embedded value depends on the relation type.
