One SELECT block after WITH and set-operation structure has been pulled
into explicit parent/child nodes.

Implementations§
Source§impl QueryBlockPlan
impl QueryBlockPlan
Sourcepub fn expressions(&self) -> Vec<&ScalarExpr>
pub fn expressions(&self) -> Vec<&ScalarExpr>
Expression nodes evaluated while executing this query block. Query
bodies under FROM (SELECT ...) are excluded because their child plan
installs its own expression scope when it executes.
