Cte

Struct Cte 

Source
pub struct Cte {
    pub name: StrRef,
    pub query: QueryRef,
    pub columns: Slice,
}
Expand description

A WITH name AS MATERIALIZED (query), which is run once and read wherever it is named.

Only the materialised ones are here. A plain WITH and a NOT MATERIALIZED one are put into every place they are named while the tree is being built, the way the reference binary does it, so by the time anything reads an Ast there is no name left to resolve.

Fields§

§name: StrRef

The name it was written with.

§query: QueryRef

What produces its rows.

§columns: Slice

The column names from AS name(a, b), as a run of StrRef, empty when there were none.
