Struct DerivedNote 

pub struct DerivedNote {
    pub anonymous: bool,
    pub view: bool,
    pub cte: bool,
    pub materialized: Option<bool>,
    pub uses: u32,
    pub name: Vec<u8>,
    pub pinned: bool,
}

Where a derived table came from.

SQLite plans a derived table by where it came from as much as by what it holds. A CTE written MATERIALIZED is never flattened, and a CTE used more than once is materialized once rather than run as a co-routine for each use. A derived table that has no name is shown as (subquery-N).

Fields

anonymous: bool

Whether the FROM term was a subquery written with no alias.

view: bool

Whether the FROM term named a view.

cte: bool

Whether the FROM term named a common table expression.

materialized: Option<bool>

Some(true) for MATERIALIZED, Some(false) for NOT MATERIALIZED.

uses: u32

How many FROM terms of the statement name the CTE.

name: Vec<u8>

The CTE’s or view’s name as written, which a CO-ROUTINE or MATERIALIZE node shows in place of the alias.

pinned: bool

Whether something outside the query reads this term’s columns by its number, so it has to stay a term rather than be flattened.

The view an INSTEAD OF UPDATE or DELETE writes through is one: the trigger’s OLD and the new values are read from its columns after the query has found the rows.
