TableRef

Struct TableRef 

Source
pub struct TableRef {
    pub name: String,
    pub alias: Option<String>,
    pub as_of_segment: Option<u32>,
    pub unnest_expr: Option<Box<Expr>>,
}

Fields§

§name: String§alias: Option<String>§as_of_segment: Option<u32>

v6.10.2 — AS OF SEGMENT '<id>' cold-tier time-travel. When Some(id), the scan restricts to rows that live in segment <id> only — useful for forensic inspection of a specific freezer-emitted segment without exposing the hot tier. AS OF TIMESTAMP <ts> (PG-flavoured time travel) is STABILITY carve-out for v6.10 — needs the freezer to stamp each segment with a wall-clock at creation time.

§unnest_expr: Option<Box<Expr>>

v7.11.7 — FROM unnest(<expr>) [AS] <alias> set-returning source. When Some, name is the alias (defaulting to "unnest" when no AS is given) and the engine builds a synthetic single-column table by evaluating the expression once at SELECT entry. Each TEXT[] element becomes one row; NULL elements become NULL cells. v7.11 supports uncorrelated UNNEST only (the expr cannot reference outer columns) and only as the FROM primary (no JOINs).
