Fields

outer: Box<SqlPlan>

Plan producing outer rows.

outer_alias: Option<String>

Alias used to qualify outer table columns.

inner: Box<SqlPlan>

Inner subquery plan (correlation predicates are injected at runtime).

correlation_predicates: Vec<(String, String)>

Correlated predicates extracted from the inner WHERE that reference outer columns. Each entry is (inner_field, outer_field).

lateral_alias: String

Alias under which inner rows are presented.

projection: Vec<Projection>

Post-lateral projection.

outer_row_cap: usize

Maximum outer rows allowed. Queries exceeding this return an error.

left_join: bool

LEFT join semantics: preserve outer rows even when inner is empty.
