Struct CteBinding 

pub struct CteBinding {
    pub folded: Vec<u8>,
    pub name: Vec<u8>,
    pub columns: Vec<Vec<u8>>,
    pub select: SelectId,
    pub recursive: bool,
    pub materialized: Option<bool>,
    pub level: usize,
}

One common table expression visible to a block.

The definition is kept as an AST id rather than a bound block because two references to the same CTE are two independent scans: each gets its own FROM-term numbers and its own materialisation. Binding once and cloning would give both references the same source ids, and the second scan would then read the first one’s cursors.

Fields

folded: Vec<u8>

The folded name a FROM term matches against.

name: Vec<u8>

The name as written, which the expansion is aliased to.

columns: Vec<Vec<u8>>

The explicit column list, when the WITH wrote one.

select: SelectId

The query the name stands for.

recursive: bool

Whether the WITH said RECURSIVE.

materialized: Option<bool>

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

level: usize

The position of the WITH that defined it in the stack of WITH levels, which is how far down the body of the definition may look.
